  • Comfort Dreams LumbarBack Support Mattress

    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.

    • Please tell us about the quality of the product. It's wonderful

  • Firm but not hard

    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!

  • great mattress

    i wanted to wait a while before i reviewed. Have been sleeping on this mattress for a month and absolutely love it. It is firm, but not hard. i am very happy with my purchase so far. I would like to update in about a year to see how it holds up.

  • Amazing Support

    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.

    • Please tell us about the quality of the product. Firmess was amazing for my husband who has back issues.

  • Shipping and Handling

    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. BUT...it 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 Im sleeping peacefully at night. Have only had it for a week, BUT LOVE IT!!!

  • Much firmer than expected

    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...

  • Sweet dreams!

    We've been wanting to upgrade to a King-size bed from our queen for years. Our lovely home, however, can only accommodate a queen-size traditional mattress due to smaller archways, etc. The answer: a King-size memory foam mattress! We purchased the Napa canopy California King-size bed (love it) and this mattress and are completely satisfied. We also had to purchase two twin-size box-springs separately to go with this. We are very happy with our purchase.

    • How did the color on site compare with the actual product? Color rendition accurate.
    • Please tell us about the quality of the product. We've only had the mattress a short time but it is very comfortable.

    I needed a bed that would support my back when sleeping and this is exactly what I got. I am so happy with this product I can scream. I would purchase another if if needed.

    • How did the color on site compare with the actual product? Product was just like it looked
