I have gone through many mattresses. I will say right off the bat that my best bed ever is a medium firm futon. It was a floor demonstration model, so it had been "outgassing" its toxic fumes for 8 months, otherwise I could not have bought it. It had a cherrywood frame, an added bonus, for less than $500.
I have bought very expensive beds which were only so-so. One of them is an all cotton mattress which is supposed to by hypoallergenic, and cost $2000 plus a hefty shipping cost. It was definitely not worth it, as it sags in places and is too soft. My husband loved it though--sure miss him over there on the right side of the mattress.

I sent a tempurpedic back to the store after one night, paying the 10% restocking fee. I do not have any idea why you guys like his mattress and I found it the most painful mattress I ever slept on. I just sank into it and hurt. That is all, pure pain for 2 hours, in whatever position, moved back to the old bed.

I had an adjustable bed which was not comfortable and also sent that back, and now use pillows (goose down) to prop up my head.

I have to be careful with the "new mattress" smell, so that's an additional problem to me, and why I finally bought the expensive all-natural bed.

If I have to go into an assisted living, it will be hard to take my queen size futon, but I do not think I can replace it easily...it was "special" and just right for me. I do not hurt on it. I do have to change positions a lot, however. Sometimes I just sleep through the night, a wonder.

I am usually comfy on motel beds, and I just wonder how they manage to get comfy beds which I have found it so hard.
