I never liked the space a bed takes up so I decided to look into alternatives some years ago when it started to offer less support.
I always had a futon so I immediately switched to that. I also bought a cheap hammock and built some hammock stands to use it indoors.
I didn't have any problems adjusting to the futon; that's what I sleep on most of the time today. I'm also pretty sure I'd have no problems with a japanese style roll up beds either (it's basically like a futon anyway).
Hammocking, though, took a bit longer. I really wanted to make it work too. To make a long story short, my initial hammock was too short and now I do have a hammock I can sleep soundly in (which I do every now and then).
I was also initially interested on trying to train myself to sleep on a flat floor... but, ummm, that did not go well and I've never returned to trying. Maybe...
I slept on a hammock for years indoors slung between two huge hooks I screwed into my walls.
It took a couple weeks before I fully adjusted. One nice thing is that when I went camping or on a three month bike trip, I had my every-night bed with me! It felt so luxurious!
I loved it, and if I was single, I'd still be sleeping in a hammock every night.
I've watched videos about how to get in one and how to orient yourself in one it's not as simple as I thought. I'm not sure if I could sleep in a position that's anything but flat.
I have acid reflux so I stack up pillows but sometime I roll over flat on my stomach and barf (yeah nice right!). But in the morning my hands are asleep probably due to my neck at a bad angle.
I'd like to try a hammock but the attachments for the ends is the biggest problem.

I've been sleeping on the floor for over two years now. At this point, I prefer it to sleeping in a bed. I started out by creating a "mattress" made of several layers of blankets. Now, though, I just put a sheet on my low-pile carpet and that's all I sleep on. I also use a relatively flat/thin pillow.
