This mattress/foundation set was purchased to replace a ten year old queen size mattress and box spring set from Simmons Beautyrest. We are about two weeks in to sleeping on the new mattress and we have been blown away with how much more rested we feel after waking up from a good night's sleep.
The old mattress had individually wrapped coils and was a high coil count, it had a pillow-top layer of memory foam which was about as thick as a memory foam topper. Sleeping on the old bed, my wife used to go to sleep and wake up with back pain. I believe it was from the pressure points created by the springs. Now with the new bed she may go to bed with a sore back, but when she wakes up the soreness is gone.
The only problem we have had in the mornings is getting out of the bed, it is so comfortable, we have had a hard time wanting to get out of it and go to work :) Some additional things to point out are that we had heard rumors that memory foam can retain heat and sleep very warm, this has not been the case with this bed. Another factor is the 'quicksand' effect we had heard about and experienced in a mattress showroom a few times. With this bed we do not have the issue of movement and the foam does not suck you in like others.
I would recommend this mattress set to anyone looking to replace a coil bed who is experiencing pressure points.
