The Major from Hellsing has a cool chair that is on an elevated platform in the zeppelin. It hides a surprise weapon too.
Axis Powers Hetalia: England tries to trick America into sitting on the "Infamous 'Sit and You Die' Busby Stoop Chair. Its evil doesn't stand a chance against Russia's, though, so it's not as cool as it could be.
Masaru's hovering chair in AKIRA, complete with bubble dome.
While we're at it, the concrete throne at the Olympic Stadium made a better Cool Chair for Tetsuo than anything else he could have sat on.
The wheelchair in the last episode of Samurai Champloo is revealed to be a cool chair because it contains a hidden gun in one arm, a stick of dynamite in the other, and more dynamite stashed under the seat, all in place to lay a last resort final blow on a weakened Mugen. It still isn't enough to kill him.
Soul Eater: While Franken Stein's rolling desk chair may look mundane, a frightful power is contained within.
Bleach has the Espadas' chairs, all of which are inexplicably about 15 feet tall and shaped like a piece of modern art. Aizen's couch shares the same absurd size and shape. Both have achieved their own fandoms.
Metron from DC has another hovering Cool Chair.
Thanos of Titan has had three "Space Thrones" made, each capable of generating a powerful, nearly impenetrable forcefield, energy-beam weapons capable of automatic targeting and firing, a teleportational device, a tractor beam emitter, and engines capable of transporting the craft through separate dimensions and realities, powerful sensor arrays, and an advanced computer system.
X-Men: Professor X once had a high-tech hovering chair given to him by the Shi'ar.
And Whiz Kid can turn any object of sufficient mass into any device he can imagine. His wheelchair being the closest thing at hand, it's been turned into a rocket-powered one-man tank on several occasions. Sadly, he's among the C-List Fodder to be depowered at the end of House of M.
The Mekon, arch-villain of the Dan Dare comics, crouched on a flying throne shaped like half a lemon.
The comics adaptation of The Thrawn Trilogy shows us the command chair on the Chimera, the Star Destroyer that Grand Admiral Thrawn picked as his flagship. It's this massive thronelike thing made out of slabs.
Every member of the Justice League of America has a chair in the roundtable, however credit for Cool Chair would have to go to the Atom, who has a hovering cool chair that's just his size.
In the Marvel verse, Satan's throne in Hell is an aversion. It looks like it was cobbled together (badly) with a bunch of wooden planks and nails. It does have an impressively tall back though. The various demon lords and arch devils such as Mephisto, some of whom even claim to be Satan themselves, hold councils around the throne. None dare claim it, for fear of being torn apart by the others.
The Jedi Council hold their meetings in a tower, where each member gets a nice looking chair that you could almost swear was built specifically for them. Sometimes, when some of the members are away, they even fill their chairs via hologram communication.
And sometimes Yoda even uses a hover-chair.
And let us not forget the Emperor's cool chair while we're at it.
In Episode I, we get a scene of Viceroy Gunray on a "mechno-throne", a cool chair that walks around on four legs - very, very slowly....
Also in Episode I, Darth Sidious uses the "mechno-throne" as a hologram projector. Let me recap: he is sitting on a throne that walks around on its own power. And he is a hologram at the time. Is Evil cool or what?
Don't forget Vader's cool chair in his meditation chamber. It's unique in that, rather than being the typical throne, it's low enough that Vader has to cross his legs when sitting in it.
However! Realize that in fact Sauron has the coolest chair of them all, as his chair routinely spawns gargantuan legions of horrifying abominations of purest, twisted evil and is the tallest tower in the whole of middle-earth! He RULES this trope!!
Also, Saruman's spiky black chair in a throne room made of spiky obsidian (film only). Christopher Lee described it as "a great place to throw a really classy party, but not too comfortable to sit in."
Let's not forget the Steward of Gondor's seat (book and film), a plain black chair below and to one side of the (permanentlyunoccupied) throne.
Those egg chairs from Men In Black may be a subversion of this. They LOOK cool, but are horribly uncomfortable and it's almost impossible to write while sitting in one. Of course, that was the point — the written exam was a Secret Test of Character; the real test was to see which, if any, of their candidates realized that they were in a situation which was singularly unsuited to writing properly; noticed that there was a useful flat surface in the middle of the room; and go ahead and used that flat surface, even if it made that horrible screeching noise.
Wild Wild West (1999) movie. Dr. Loveless' wheelchair had a built-in gun and could turn into a 4-legged mini-mecha.
In the first Chronicles of Narnia film, the White Witch's throne of ice was a Cool Chair — literally. The four thrones at Cair Paravel toward the end of the film were quite spiff.
Parodied in the Austin Powers series, where Dr. Evil's Cool Chair keeps malfunctioning, or he just doesn't know how to work it.
Doctor Doom is seen briefly in Fantastic Four: Rise of the Silver Surfer sitting in a rotating chair with LCD screens on its armrests in a room where the walls are covered with larger monitors. Shame so little of it was shown, as it looked rather cool.
The Riddler's throne from Batman Forever might be a subversion of this.
Patrick Stewart's role as Charles Xavier in X-Men turned a wheelchair of all things into a freakin' cool chair. Those brain probes he uses for mass mind-readin' can't hurt the look, either.
In The Stuntman movie, the director character has a hovering cool chair (suspended by a crane) he uses to pop in and out of scenes.
The new Star Trek film features an awesome captain's chair.
Xerxes's gigantic throne in 300, which is the size of a small house, is carried around by no fewer than 100 slaves, and is lavishly decorated with statues, ivory, and gold.
In Night at the Museum: Battle of the Smithsonian, the villain steals a pretty sweet looking couch to use as a throne.
In the second Artemis Fowl book, Opal Koboi had a hovering chair.
In Isaac Asimov's Foundation story "Bridle and Saddle" (AKA "The Mayors"), a ruler had a glowing chair that could float due to its shielded nuclear motor.
In Dune, the Emperor's throne was a "massive chair carved from a single piece of Hagal quartz". In Dune Messiah this is changed to "Hagar emerald" (probably a typo). The aborted 1975 film version of Dune would have had the Harkonnen Capo Chair,◊ designed by H. R. Giger of Alien fame.
The Silver Chair from The Silver Chair, which apart from looking cool has the magical ability to completely brainwash its occupant for 23 hours a day, and keep him imprisoned for the remaining one.
Nero Wolfe has a desk chair in his office that is custom-built (under his own supervision, of course) to accommodate his great bulk. The springs are designed to support up to 500 pounds, and are so stiff that Wolfe's assistant Archie Goodwin can barely get the chair to tilt backward when he sits in it. There's also the red leather chair in his office that's reserved for his client (or Inspector Cramer). If it's a story where Wolfe has multiple clients, the one he considers most important gets the red leather chair; if it's one with no paying client, it goes to the person Wolfe is more or less working for. In any case, the person who gets the red leather chair is virtually never the guilty party.
The Iron Throne in A Song of Ice and Fire is intentionally Cool, but Inefficient. Aegon the Conqueror took the swords of all the defeated lords of Westeros and forged them with dragonfire into a scary but still very sharp throne, saying that a king should never sit easy. Kings often cut themselves on the throne, and legend states that it has killed at least one of them.
The populace seems to think that it might be magical and harm only bad kings. Joffrey gets stuck with it when he's at his most arrogant and bratty after the Battle of Blackwater (and goes crying to Mommy). Also, Jaime mentions that Mad King Aerys always has scabs from sitting on the Iron Throne. Both, of course, are awful rulers, so the assumption is that the throne is rejecting them. Of course, it could also just have been a really bad idea to create a chair out of swords.
The Eastern Empire from Mercedes Lackey's later Valdemar books also features a throne of blades, except it's all the personal weapons of every leader the entire line of Emperors has conquered in hundreds of years of history.
Somewhat subverted in Garfield's PET FORCE, a series of short young-adult novellas written by Jim Davis, in which Garfield, Odie, Nermal, Arlene and Pooky are sucked into the universe of a comic book starring characters conveniently similar to them. The planet they end up on is a monarchy, and the king is...Jon Arbuckle. Since being royalty can do little to change the fact that he's still fundamentally Jon, he's had the traditional throne replaced with a recliner upholstered in naugahyde, chosen on the basis that stains wipe right off.
The throne of Kinakuta in Neal Stephenson's Cryptonomicon. It looks like a chair designed by a Scandinavian with twin degrees in engineering and semiotics and given a blank cheque. When the Sultan sits in it, you know who's in charge here.
The titular Ravenor of the Warhammer 40,000 novels has his Cool Chair Life support Prison, complete with Psi boosters, Communication jamming and intercept equipment and hidden machine guns.
A tagalong in one of the books even privately refers to him as 'The Chair'.
William Albacastle / Willy Pete, authorial character of the White WolfMage: The Ascension supplement Iteration X and a major character in the novel Judgement Day by Bruce Baugh has a damn cool chair. The fact he's a technophillic quadrapalegic who uses waldoes to build telepresence drones and whose motorized wheelchair houses treads, robotic arms, and Hades knows what else gives him a good excuse to have one.
Patrician Vetinari's seat at the foot of the steps leading up to the long-unoccupied solid gold throne of Ankh-Morpork which the book Men at Arms reveals is actually fake, made of wood and so rotten that it would crumble should anyone attempt to sit in it.
Discworld addresses this idea again in The Fifth Elephant, with the Scone of Stone: revered seat cushion of the Low King of the dwarfs.
If "cushion" is really the right word for a baked good the consistency of stale granite.
When Lord Snapcase (not-yet Homicidal Lord Snapcase) replaces his successor Mad Lord Winder, the first thing he does is ask if the chair swivels. The secretary responds he can get a skilled swiveler first thing in the morning.
In David Eddings' The Belgariad, Brand, the hereditary Rivan Warder, has a seat below the empty throne of the Rivan King.
This is actually a reference, unintentional or not, to Denethor, Steward of Gondor in LOTR who sits on a plain wooden chair beneath the Gondorian throne (on the third step I believe)
The chair in the courtroom of the Wizengamot in Harry Potter has chains that, depending on the occupant, may coil up and tie him or her to it. It seems to only do it if the occupant is perceived to be potentially dangerous; in the Death Eater trials Harry sees in the Pensieve, it chains up several Death Eaters, but when Harry himself comes to sit in it in Harry Potter and the Order of the Phoenix, it lets him alone.
The Chairmaker in Use of Weaponsmakes a chair out of his step-sister's bones, whom he murdered. Nobody sits on it though.
Live Action TV
Number 2's Ball Chair in The Prisoner. The desk it faced had several phones and a set of controls.
It's Color-Coded for Your Convenience, as well: a Federation chair is done in soothing shades of beige, whereas Klingon furniture is all made from black leather and bolted-together slabs of iron. But the Klingons like it that way.
In the Star Trek: Enterprise episode "Singularity", the crew become obsessed with trivial nonsense due to Space Madness, and engineer Trip Tucker went all nuts trying to design the Ultimate Captain's Chair with interactive status displays, secondary helm control, inertial micro-dampers and cup holder (but apparently No Seat Belts).
"I know you don't think this chair is important, but you're wrong. What's the most critical component on this ship? The main computer? The warp reactor? Uh-uh, it's the crew. And the most important member of the crew is the Captain. He makes life and death decisions every day and the last thing he needs to be thinking in a critical situation is, 'Gee, I wish this chair wasn't such a pain in the ass.'"
Referenced a few times in Star Trek: The Next Generation. One episode that stands out is where Worf has to play the role of captain to fool some 80-year-old Klingons fresh out of stasis that the Klingon Empire controls the Federation. After succeeding, Riker asks him how if felt being captain. Worf's response is thus: "Comfortable chair."
Made all the more hilarious by the fact that he spent most of his run on TNG standing, save for when he served at the front consoles periodically during the first season. At least he got to sit down on the Defiant, though, either at tactical or in the captain's chair.
Worf actually had his own Cool Chair in his quarters. It's a real chair, too: a Stokke Garden chair designed by Peter Opsvik in 1985.
On Friends, Rachel buys a new armchair. It's really, really nice. So nice, in fact, that Joey deliberately breaks his leather Barcalounger in a desperate attempt to be allowed to sit in it. Twice (long story...).
SG-1 gets a Cool Chair too in the form of General Hammond's chair. In "Proving Ground," Daniel (who is currently the leader of a fake alien incursion for a training exercise) gets to sit at the desk and revels in how comfortable it is. In "Prometheus Unbound", Hammond returns to the SGC to recruit Daniel for the latest flight to Atlantis. When Jack asks him if he misses the chair and wants it back, Hammond says yes... and has the chair shipped to his office in Washington. That must be a damn comfy chair. Possibly a reference to something his actor Don S. Davis said in an interview. When asked if he could play any other role in the show, who would it be, he replied, "I'd be my own damn role. I have the best chair on the set."
In Stargate Universe, after discovering the bridge of Destiny, you can bet practically everyone is having an internal moment of squee when they first sit in the Captain's chair.
Let's not forget Baltar's infamous swivelling chair in the original Battlestar Galactica. Though how he got up there in the first place is beyond me.
Averted on the new Battlestar Galactica. As part of the design of the 2003 mini-series, the writers and producers attempted to avoid as many of the standard stylings of typical TV Space Opera. Commander Adama and Colonel Tigh always stand in Ci C. Some folks think they didn't really think it all the way through...
Having been crippled, Davros, the creator of the Daleks and recurring villain in Doctor Who, has his lower body encased in a cool chair by the time of his initial appearance in Genesis of the Daleks and retains it in later appearances.
There's also the high-backed green throne used by the eponymous individual in "The Keeper of Traken."
The Frank Lloyd Wright chairs in the council chambers on Babylon 5, and the command chair on the White Star-class ships. One of the buttons on the latter was programmed, at the battle of Corianna VII, to detonate 500 Megaton thermonuclear mines. Can you get any cooler?
A Genre Savvy moment in Rome has Cassius trying to convince Brutus that the cool chair Caesar has ordered for the forum is actually a throne and indicative of a thirst for power. Brutus claims that "thrones are usually more decorative. That is decidedly plain and chair-like."
In the first episode of NCIS, Ducky and DiNozzo quickly snap photos of each other sitting in the President's chair on Air Force One.
The Diary Room chair on Big Brother. Not particularly cool as a chair, but very definitely shorthand for "Draaaaaaaa-mah! is about to occur!"
Dad Anyfamily's mobile (as in gasoline-powered) chair from Roundhouse. It comes equipped with a TV, a propane grill, a cooler, and even brake lights.
The black leather chair contestants sat in on the game-show Mastermind. It was considered so cool that it was once kidnapped and held for ransom; the original is now in the house of Magnus Magnusson's daughter.
The Iron Throne from Game of Thrones, although by all accounts it's not very comfortable to sit on.
After the death of a colleague, Booth on Bones goes on and on about how much he wants the man's chair. Others wonder if perhaps this is his way of coping with grief, but Booth insists it really is just about a cool chair.
On Revenge, Victoria's lounge chair "throne" is so iconic to the series that when events forced her to get rid of it (it got badly stained), it received a memorial title card at the end of the episode.
Warhammer 40,000: SKULLS FOR THE SKULL THRONE! Khorne (he of BLOOD FOR THE BLOOD GOD! fame) sits on a massive throne of brass in the center of his fortress, which sits on a mountain of skulls in a lake of blood. Skulls taken and blood spilled by his warriors end up in the pile/lake, representing how his power waxes and wanes with the other three Chaos gods'.
The Emperor's Golden Throne might count too, despite the fact that it's not so much a chair, than an elaborate life support device the size of a large building. Apparently the part where the Emperor's body lies does look somewhat like a throne, though.
There is also Inquisitor Lord Karamazov's Throne of Judgement, which is essentially a Space Marine Dreadnought with a chair top.
The Scarlet Throne◊ of Exalted is an elaborate thing made from magical jade of each colour carved into the shapes of the Five Elemental Dragons in a protective and deferential pose to the sitter, and has been the main symbol of the authority of the most powerful person in the world for 700 years.
It's also a powerful magical artifact, and possesses at least some degree of consciousness: When the current regent seated himself upon it, the heads opened their mouths, hissed at him, and pulled back in a pre-striking pose. He hasn't dared enter the throne room since. You know you suck as a ruler when your own seat of office hates you.
Yu-Gi-Oh!: Elshadoll Shekhinaga is Nephilim using Apoqliphoth Killer as a throne, after forcing it into her servitude.
A golden throne, studded with platinum and decorated with dragon bones, and carved with the glorious feats of the town's ruler, doesn't even get near how awesome chairs and thrones (as all furniture) can become in Dwarf Fortress.
Sonic the Hedgehog: Dr. Robotnik has various incarnations of his signature Eggmobiles, which manage a trifecta of Cool Chair, cockpit of sundry Boss Battling machines, and omnivehicle escape pod. So enamored is he with his flying chair that it's rare to see him actually standing.
We never see her sit in it, but Azala in Chrono Trigger has a throne made of bones in Tyranno Palace. Choosing to sit in it causes the character doing so to give an Evil Laugh.
Some Castlevania games have a sidequest centered around finding and sitting in Cool Chairs.
Castlevania: Dawn of Sorrow has a soul you can collect which, when equipped, will regenerate health at a fairly generous rate whenever you're sitting down-be it in a Cool Chair, a few boards and dowels barely held together with glue, or a crate.
The Frozen Throne of the Lich King in Warcraft games - a chair magically carved out of glacial ice, which doubles as Ner'zhul's phylactery. There's also a place called the Throne of Kil'Jaeden, but it's not an actual throne. Whether the Legionlord has an actual Cool Chair remains to be seen, as surely no self-respecting demon lord would go without an obsidian throne covered in skulls and spikes.
Several CoolChairs can be found in World of Warcraft, usually in various throne rooms. Kel'thuzad has a particularly cool looking one, which is sadly somewhat wasted, as he's a semi-incorporeal lich and doesn't have the necessary bodyparts (like everything below his torso) to actually sit on it.
In Halo the prophets glide on gravity thrones, which have Deflector Shields and can shoot lasers. Normally Master Chief vs. an old man wouldn't be much of a fight, so it's a good thing the Cool Chair fixes that.
Every Shipmaster has his own on the bridge of his ship. It's a fairly simple gravity throne, minus any of the Prophet's offensive attachements (presumably), but the simple fact that Elites like Rtas Vadum and Thel Vadam direct planetwide destruction from them is enough to make them cool.
Sebastian Krist's chair is so cool that it comes with built-in rocket launchers.
There's one of these that Bowser usually sits on in the Super Mario Bros. series, with a clear example of such a sinister spike-covered throne found in the Mario Party Bowser mini games.
Resident Evil 4's Leon Kennedy finds a Cool Chair while venturing into the final areas of the game. You even get an action command to sit it in, Dracula style (Doing so will reveal a collectible).
Organization XIII of Kingdom Hearts has an entire circular meeting room with no less than thirteen cool chairs for each member of the Organization. Each one is raised to ridiculous heights on top of a plain white tower, and they seem built for people who are about ten feet tall (less of a problem when you can teleport). Since all the elevations vary depending on rank, it's amazing that they manage to have meetings without having to shout at each other to be heard. Naturally Xemnas, being the leader, has the highest chair.
Ape Escape's evil genius simian antagonist Specter is seldom seen without his levitating chair. In the first game, he even fights the first half of the final battle in it. It doesn't appear to have any weapons of its own, but it does teleport and apparently give him mind-control beam and energy blast attacks, so it's pretty cool.
Nethack - Occasionally you can come across a throne. Sitting in it can net you something nice...or something horrible.
Mass Effect: The Normandy SR-2's pilot chair is so spiffy that Joker has a Nerdgasm over it. Given that he's got a bone disease that requires him to spend most of his time sitting, his reaction is justified.
The Illusive Man's chair is impressive if only for its elegant simplicity. There's a reason why, in Mass Effect 3, he gets annoyed when Shepard sits in it.
In Wii version A Boy and His Blob, the emperor sits on a rather slimy throne which is has several heads very much alive.
Kristoph Gavin in Apollo Justice: Ace Attorney gets a very expensive looking cool chair in prison. Chairs, nail polish and reading are his only hobbies, and given the circumstances, this means he's doing quite well for himself.
Algol of Soul Calibur 4 and 5 sits in his throne during his pre-battle cutscene, and can both sit in it and WIELD it (admittedly telekinetically) during actual gameplay.
MapleStory: You can earn increasingly cool-looking chairs to sit down in and restore HP and MP.
Nine of them in The Elder Scrolls V: Skyrim. The thrones of the Jarls come with a Reclining Reigner animation, and the royal throne in Solitude has the prim and proper upright animation. There are also several of them in ancient ruins, usually filled with fearsome Draugr bosses.
Drhorribles Sing Along Blog: Dr. Horrible has a big, giant overstuffed chair◊ in his laboratory. It's a bit too gaudy to be a proper Evil Overlord chair, which makes it probably an Affectionate Parody. Plus, meta-wise, the chair belonged to the person in whose home they filmed the Billy shots. "The chair really is that big," Whedon was quoted as saying. "We did not bring a chair increaser."
The online program Habbo Hotel has the throne. Unfortunately, to obtain such an item means you have to scam it, trade for it or... gulp... buy it. :(
Considering how much The Nostalgia Critic talks about it in Kickassia, his rocket chair must have been really awesome, even if it's never seen on-screen. He claims it could levitate using science.
Villains with a preference for high technology (and occasionally heroes, too) often use a hoveringCool Chair, which can move them around their screen-covered command-center without the inconvenience of getting up and walking. I recall an episode of the old Spider-Man animated series, when J. Jonah Jameson is 'invited' up to SHIELD's Helicarrier, and we get the Chair Reveal on Nick 'The Pirate' Fury. He's sitting in some sort of awesome, electric, hovering chair. Just to underline the "These guys have loads of cool stuff" point
In another episode of Spider-Man: The Animated Series, Norman Osborn hired Spencer Smythe to create the Spider Slayer, the terms of their deal included Norman financing the development of a hover chair for Smythe's son. In the end of the episode, Spencer was believed dead and his son, blaming Spidey, Osborn, Jameson and Eddie Brock for that, agreed to work for the Kingpin, who provided him with a hover chair.
Professor X in the 90's X-Men cartoon had a hoverchair (because he had it in the comics at the time, though the cartoon doesn't explain where he got it, and presumably it was easier to animate).
Parodied on The Simpsons, where Mr. Burns offers to use his influence to get Homer into college to actually get his nuclear physics degree, saying "I have a chair on the admissions board of Springfield University". His "chair" turns out to be a giant throne with devils carved into it, skulls for the handrests, and two attack dogs chained to it.
How can we not mention Stephen Hawking's wheelchair from the same show? It could fly and was loaded with more tools than Inspector Gadget.
Professor Farnsworth from Futurama pilots a flying, armed Laz-E-Boy when they are pushed back to 1940's Roswell.
My Little Pony: Friendship Is Magic: Discord fashions himself quite an evil-looking throne - a dark gray and deep red color scheme, a stylized skull shape with pointed teeth at the top, and a huge pair of antlers sprouting from the skull for added demonic imagery - and plops it right in the middle of Ponyville so that he can observe the chaos he's wrought firsthand.
In Equestria Games, the four princesses each have their own elaborate thrones at the Games, emblazoned with stylized renditions of their cutie marks. This is similar to the VIP seating for the heads-of-state at the Olympics, including the leader of the host nation.
Big Bad Megabyte in ReBoot had a hovering Cool Chair. Of course, sitting in it required him to take his legs off to attach himself to it. He often had one of his Mooks polishing his legs while using his chair.
When Megatron was still in pieces, Professor Sumdac used Megatron's hand as a chair.
And after Megatron rebuilt himself and captured Professor Sumdac:
Megatron: I trust you're comfortable in your chair?
In Batman: The Brave and the Bold, episode "Trials of the Demon", a demon lord who is banished to his own personal pocket dimensional prison turns out to have a giant stone throne covered in spikes in there. Keep in mind that he's the only being in the entire prison, so you have to imagine: at some point he had to have formed a throne himself from the rocks just because a demon lord's gotta have a throne.
Jafar in Aladdin has a throne that's basically a couch with a giant carving of a cobra's head above it and more cobras for the legs. He also chains Princess Jasmine to it. Of course, the original throne of the sultan of Agrabah was pretty cool too, having an elephant carving.
In Avatar: The Last Airbender , the Earth King has an ornate throne worked into an absolutely enormous wall fashioned in the likeness of a badgermole, and covered in what appears to be gold and jade. Firelord Sozin had a golden throne before a similar wall worked with a golden dragon and surrounded by fiery cressets. After he crosses the Moral Event Horizon this is replaced with what seems to be a simpler seat... that's hidden behind a wall of flames in an otherwise unlit hall.
Real-life example: the term "chairman" comes from a time when all the members of a committee, save for the most important one, had to sit on benches. The most important one got a chair, which, when everyone else is sitting on benches, seems pretty cool all by itself.
In the British House of Commons, only the Speaker has a chair. Everyone else sits on benches.
Subverted in the House of Lords, where while the Lords do sit on benches (admittedly really, really, posh benches), the "chairman" of the House (formerly the Lord Chancellor, now the Lord Speaker) does not get an actual chair but rather sits on the Woolsack, which is Exactly What It Says on the Tin: a sack full of wool. Originally, this signified the importance of wool to England's economy; however, the sack was destroyed in The Blitz, and after World War II, it was replaced with a new sack stuffed with wool from all over The Commonwealth (representing Commonwealth unity and, one supposes, the ongoing love affair between English-speakers and wool). Despite the absence of a back or arms (it does have a small backrest), it's apparently quite comfortable.
There's also a Judges' Woolsack, another (much longer) wool-filled cushion right in front of and below it, where the Law Lords—Britain's highest judicial authority until they were moved to the new Supreme Court of the United Kingdom in late 2009—sat during the State Opening of Parliament (although any Lord may sit on it during normal session); the Justices of the Supreme Court continue to sit on the Judges' Woolsack during the State Opening (Supreme Court Justices are still formally Lords, but are barred from sitting or voting while they serve). Double Subverted in that there is a rather cool chair in the Lords Chamber—it's the monarch's throne, from which he/she gives the Speech from the Throne every State Opening of Parliament—and unlike the Judges' Woolsack, if you're not supposed to be sitting in it but sit in it anyway, you will get in trouble.
The long-running TV show Jim'll Fix It featured a large chair for Jimmy Savile with concealed compartments that would open when he pressed the right button. When Tom Baker and K9 were on the show K9 said it was pleased to meet "Mr Savile and Chair". (Known in retrospect to beBlatant Lies, but the Doctor ain't risking Reapers.)
The Atlantis resort and watermark in the Bahamas gives us The Golden Throne◊, a seat that guests are free to sit in (one at a time... normally)◊ and take pictures in for free.
The "thrones" occupied by mall Santas tend to be fairly impressive to look at, at least to the small children who come to sit on his lap.
