I've had this mattress for 3 years. I haven't seen many long term reviews of this mattress, so take heed. About 6 months ago I noticed that the memory foam has almost entirely lost its memory. Now its just a squishy foam pad that springs right back and has lost much of its original support. Compared to the high end foam mattresses, this is still a tolerable value, however, i'm very disappointed with its longevity, or lack thereof, and couldn't recommend it.
