This trope describes a character that just loves sleeping. They frequently take naps and may outright consider sleeping to be an art or hobby.
Often they will take their going to sleep routine very seriously because for them, it's a ritual. What they eat and drink before going to bed is important — a glass of warm milk is common. They are likely to wear nice pyjamas and perhaps even a nightcap. They will pay attention to the place where they sleep: a nice couch at the office will do just fine, but at home, they will have a good bed with fluffy pillows, a nice comforter, and clean, freshly washed sheets. A sweet pet bed is a variant for animals. They will often beg for Five More Minutes when woken up or violently attack the awaker.
The reasons for this vary: They might really dislike active lifestyle and action-oriented hobbies. They can be fond of vivid dreams and extra adventures and memories they provide. They might be aware that lack of sleep will make them cranky and annoying. Perhaps they just love how fresh and alert they feel when they wake up after a really good night's sleep. It might help them to focus. Or they can be simply too lazy for other hobbies and interests. They might be The Sleepless who really longs to sleep.
Compare Big Eater who has a similar attitude towards eating and often has this trait. Often overlaps with Heavy Sleeper (hard to wake up), Sleepyhead (dozes off often, whether they want to or not), An Odd Place to Sleep (falling asleep in at almost any place), and Not a Morning Person (people who dislike waking up and morning routines).

Sir Simon: Far away beyond the pine-woods, there is a little garden. There the grass grows long and deep, there are the great white stars of the hemlock flower, there the nightingale sings all night long. All night long he sings, and the cold crystal moon looks down, and the yew-tree spreads out its giant arms over the sleepers.
Virginia: [whispering] You mean the Garden of Death.
Sir Simon: Yes, death. Death must be so beautiful. To lie in the soft brown earth, with the grasses waving above one's head, and listen to silence. To have no yesterday, and no to-morrow. To forget time, to forget life, to be at peace.
