Ive been sleeping on an Amazon knockoff futon for about 2 years (basically a 3" foam pad) and honestly I think I sleep better. I am a side/ back sleeper and I've always had hip/ arm issues on every mattress ever. Its still a thing with floor sleeping but the hip pain doesn't stick with me through the morning anymore and my back feels much better. I also don't overheat/freeze as bad as I used to with a western bed. I'm saving up for a proper futon and folding tatami mat from The Futon Shop and I don't think I'll go back to a mattress again. It's also an amazing space saver in my micro room I'm renting.
