I had a fancy ass futon for about 2 years, first on the floor and then with all kinds of extensions (like a mattress topper and slatted base) it was killing my back. After that I've tried 3 different mattresses (two spring ones and a memory foam) and now finally a proper box spring bed from an actual furniture store that the salesperson helped us choose -- and my dog does it make a difference! Also buying a good pillow helped a ton. I've decided I'm getting too old to sleep in an unsuitable bed. Most of the hotel beds I've slept in after getting the new bed feel like crap.
