  • 5 years of good sleep!
    Verified Purchase

    We bought this bed about five years ago from Overstock. It has held up pretty well -- my husband and I are both large people, so over time some of the memory foam hasn't quite kept its shape where we sleep most, but I really can't fault the mattress for that. It still provides a lovely night's rest. My back problems have just about disappeared since getting this mattress, and when I travel for work, I can't wait to get back to a good night's rest on my memory foam bed!

  • Much firmer than expected
    Verified Purchase

    If you like your mattress pretty firm, then this is for you... We ended up having to get a mattress topper to soften it up a bit... Mattress firmness is pretty subjective so I guess it all depends on what you like... I wouldnt buy another mattress online again... It ended up working for us but only after we bought the topper...

    The mattress is better than I really thought it would be. We have tried quite a few mattresses in stores and that made this a real deal, since we couldn't try it first. I have had many back surgerys and this mattress is wonderful. IThe mattress is very comfortable. Now we both can slee[ all night and wake up feeling good. No more back aches when we awake.

  • Firm but not hard
    Verified Purchase

    Bought this about 3 month ago to replace the select comfort I bought for 4 times the money 2 years ago. I never slept on a memory foam mattress before, and I am very pleased with the feel. You don't really sink in like I thought you might, that's what has stopped me from buying a foam mattress before. I have problems with my hip joints aching half way through the night and I get that a lot less on this bed than I did on the select comfort (digital display on the pump controller burned up, and you have to buy a whole new pump to replace that, not willing to sink anymore money into this overpriced air mattress). Even if it lasts only 2 years, I'm still ahead on this deal!

    The first night my husband slept on this mattress he woke up with less back pain. He was shocked. He has been in physical therapy for slipped discs but sleeping on this mattress alleviates morning stiffness and pain.

    I am a single girl and often times, if I need a large piece of furniture, I have to see “IF" they deliver, will they bring it up stairs for me? How am I going to place it once it's inside my apartment? With this mattress, all those things ran through my head. was so simple and easy to place. It was a memory foam which came in a large cardboard-covered roll. Very easy to drag to the bedroom. They delivered it outside my door, which means they brought it up stairs. I dragged it to my bedroom, followed the instructions for opening it, and placed it easily on my box spring. Let it sit for 72 hours to readjust and now happy to report that I’m sleeping peacefully at night. Have only had it for a week, BUT LOVE IT!!!
