After retina surgery and the placement of a gas bubble in the eye to press on the retina you're given no choice! The bubble needs to stay in place.
There are some custom chairs available for one to sit / rest in that might help. See

I didn't get one and frankly it's been h*** trying to sleep. I tried an inflatable pillow with a hole for the face to rest in but it was not restful at all.
