People Sit In Chairs
--except when those chairs are really uncomfortable.
This is when one species has trouble with furniture made for another species due to differences in anatomy or culture. A common example would be a Winged Humanoid
or Lizard Folk
(with their thick inflexible tails) having trouble sitting properly in chairs built for human use--or, for that matter, vice versa!
A sister trope to Operator Incompatibility
Anime and Manga

- In both Attack of the Clones and Revenge of the Sith, Yoda is depicted as having a visibly smaller lightsaber handle than Jedi who are of more human proportions.
- In Rogue Squadron, the first book of the X-Wing Series, Wedge becomes apprehensive when he learns that his Verpine crew chief has "tinkered" with his brand new starfighter, as he remembers horror stories from other human pilots of ships optimized for Verpine ergonomics. His X-Wing turns out to be fine, however.
- The novel series as a whole tends to Hand Wave how Twi'lek and other nonhuman pilots can fit their appendages inside flight helmets. It's averted in the comics, however, where nonhumans are depicted as having helmets with the proper ergonomics for their species.

It fits Ax better than normal chairs since his species, the Andalites, are basically centaurs.
- Andalite ships in the Animorphs series are very uncomfortable for human passengers due to their lack of seating at all.

- In the Heechee Saga; the chairs on the Heechee ships abandoned at Gateway asteroid all have V-shaped seats which are incredibly uncomfortable.
