We've been sleeping on a set of three queen-size Small Wonder futons (organic cotton and wool) for about three years. Each futon is about two inches thick, making it possible for one person to turn the individual layers periodically and keep body impressions from forming. Also, with three layers, I can take one off for unexpected company and put it almst anywhere. I did have to get a prescription for a chemical free bed, but that was not a problem. I would have preferred to make the whole shebang from scratch, but I do not have a heavy duty sewing machine and I do have a connective tissue disease which gives me hell a lot of the time. HOWEVER! For those of you who might want to experiment with making your own organic wool beds, I would like to offer the organic wool free of charge if you want to pay shipping or come by and pick it up (I live about 40 miles SW of Dillon, Montana in the middle of nowhere). This wool is not cleaned or combed, that's your job. It comes from my beloved Navajo-Churro sheep. Feel free to email me at sheepislife at gmail dot com if you're interested, and happy sleeping!
