The air mattress I've been using as a bed sprang a leak a few days ago. While I can use scotch tape and a business card in such as way as to patch it so that it no longer goes sssssss as soon as I reinflate the mattress, I still inevitably wake up flat against the hardwood a few hours later. Somewhere I have the official patch kit for it, but I can't bring myself to look for it.
Upon waking up this morning I told myself that it's time to buy a bed. I have no reason not to do so now; I can claim neither poverty nor lack of space as reasons to continue to practice of floor-crashing. Beds are hard to move, is really the only thing. But maybe if I don't think about moving, I'll actually live here for more than eight months or whatever.
Futons Across America
I bought a futon about 6 years ago. The futon pad itself is getting a bit on the 'mushy' side and may soon need to get replaced or re-fluffed or whatever they do to them. The futon pads can be more expensive than the frames.
I got one of those metal tube based full-sized futon frames which can digivolve into a couch. They're inexpensive but I've seen several toss out on the side of the road because they were all bent up. Mine's still in good shape but that's because I don't have 500 pounds doing the humpa-humpa on it nor do I have people sitting on it as if they're trying to perform a KinnikuBuster.
I paid roughly $230 for both frame and pad (this was 6 years ago) and overall I've been happy with my futon.
