That's pretty much what we have. It's called a futon, but it's really a somewhat-deconstructed spring/foam mattress, not just a mass of padding. It goes on an IKEA-type platform bed I've had for about 30 years (don't wanna break up the set). I find it very comfortable to sleep on. DW prefers her old Sleep Number bed, but I never cared for that at all. At least we can both agree on this mattress. And the strips beneath the mattress can be adjusted for firmness (of course, we're at polar opposites of the firm/soft scale). The bed incorporates a headboard and footboard and nightstands, which has made putting it into rooms a little limiting. But it's a beautiful piece (all teak) and it does come with drawers underneath. So it has stayed.
