There are all sorts of beds for all sorts of people. A decent bed shop lets you lie down on them and see how you like them. I wouldn't buy a bed I hadn't tried.
(We were given a bed as a gift when some friends emigrated. We used it recently when we were decorating the main bedroom, and we slept noticeably less well. It does make a difference.) @yourautisticlife@caocancio@eo@actuallyautistic
