you really have to try it to believe it! i was worried about buying a mattress online without ever trying it out first, but this was by far the best thing i've ever bought, hands down. i was looking for a memory foam mattress but couldn't afford a tempurpedic, so i read the reviews on this one. it had great reviews, and they were all correct. i used to wake up achy and stiff, sometimes in real pain, but i fall asleep so fast on this mattress, and i sleep through the night, hardly even moving, and wake up feeling as if i had slept on a cloud. i was looking for a somewhat firm mattress, but the reviews on this one said that the soft one was firmer than expected, so i tried it and it's perfect. i've already recommended it to all my friends and family!
