I ordered my 'real' futon here (just the cotton bed that goes on the ground), and they were able to special-order it in any color/material/thickness/etcetc. It was fun to look at the options. And oh, my back loves it. I think I'm one of the few people in the world who has switched from a memory-foam mattress to a super firm solid cotton mattress and hasn't looked back.
Anyway, they have a lot of cool futon frames if you want the western folding kind. I ended up buying an unfinished platform frame from them because I needed under-the-bed storage. It hasn't diassembled/reassembled well due to some overzealous powerdrill action stripping the screws (oops), and when I went to the store to try and order some new screws the owner told me it wasn't possible. Oh well... he pulled out a box of spare hardware and picked through it to find some suitable replacements for me, I appreciated that.
They also carry tatami mats, nice lamps, and some very lovely minimalistic bed frames.
