We have the S & F latex mattress (no coils). It was really comfortable when we first had it, but I am now not really sure it is any more comfortable than our old bed (Simmons Beauty Rest). It is supposed to last 15 years, though, and we don't need to turn it. The lady at the store said something about the bedding, that it shouldn't be stretched too tightly or something, so that might be my problem.
