    • Great bed, excellent price

      We had just bought a latex mattress and it was so bad we were looking for a replacement immediately so we decided on this one after reading all the great reviews. The bed was shipped UPS which was very convenient. No need to wait for any movers to deliver the mattress. easy set up and out mattress had no smell what so every. We waited one day after opening the package and the bed was good to go. Very comfortable and slightly firm. Other mattresses had caused back pain but this one does not cause any back pain for us. Highly recommended. No need to buy the higher priced ($$$$) mattresses, we looked at them all and this was the best decision.

    • Tom

      Bought about 3 months ago, came 2 days late. Arrived in a nylon bag that I had to carefully cut out as the bed had already tried to expand and couldn't be removed from it. No truly bad smell that I could tell, but wife said there was...She ordered the "medium" firmness against my better Judgement as I have had lumbar back surgery years ago and wanted a firm mattress. Too soft for me, wish I'd stuck to my guns and demanded a "firm", other than that a great gel foam mattress for the price.

    • Love it!

      This bed is great! I got this bed about a month ago, my old bed was giving my husband and I back problems, so we decided to go with a memory foam bed. I wanted to get a gel memory foam mattress because it says it is cooling and I like to have a cooling sensation when I sleep. Our backs are feeling way better after sleeping on this bed and it's so comfortable. Not too soft and not too firm. I didn't really notice if it's cooler than other beds but it doesn't sleep hot which is great. I'm pregnant too and this bed helps me sleep through the night unlike my old bed. I just hope this bed last me for a very long time because I love it!

    • Fantastic support and comfort at any price

      As someone who is very, very fussy about sleeping comfort and support I couldn't be happier. My husband swears that he is sleeping more soundly and I know that I am sleeping more comfortably. I was concerned about not being able to try it out (or return it), but was willing to give it a try. The reviews were very accurate. It inflated very quickly and although it did have a bit of a smell, that dissipated within a few days. We were able to sleep on it from the very first night. In fact, we were so pleased that we purchased one the next week for my mother in law. She loves hers also!

    • Comfortable

      I'm happy with this purchase. I have degenerative disc disease and a herniated disc at L5-S1. My old serta pillowtop mattress began to sag and get lumpy, so I braved the transition to a firmer healthier alternative, memory foam. I did a lot of shopping around and asking for advice before buying this particular product and I'm very pleased I decided on it. I get restful sleep and my back seems satisfied. It was definitely a good choice for me. :)

    • So far, REALLY good

      I am 6'4" 240lb and I have been sleeping on a inner spring queen mattress my entire life. Once I got married, it was much more of a struggle to share the queen because of my height. I cannot recall the last time I was able to sleep without my feet hanging off the bed or be forced to wake up due to lower back pain. We had to flip our mattress all the time! After doing extensive research we decided to purchase this mattress from overstock (12" cooling gel memory foam) and I am SO glad we did! The bed is amazing. It has been 2 weeks now and I am sleeping great and waking up with NO back pain. I run hot and my wife runs cold, but the mattress is perfect for both of us! Not too hot, not too cold, just right (then again its not summer yet and I live in Texas, so we will see). The mattress inflated in a matter of minutes, but I gave the mattress 4 hours before testing it out. It smelled a little, but nothing too strong to sleep on. My wife is pregnant right now and she wasn't bothered by the smell (if that tells you anything). At the end of the day we couldn't be happier with this bed!

    • Wash the cover

      I live in a rural area so shipping takes longer. I don't know if the prolonged time in the bag made the bed stink longer but it took almost 3 days before I could stand it. We had a spill on the bed so we took the cover off and washed it, that helped the most. I'm a larger guy 320 lbs and my wife is smaller ( she said i cant give her weight out but she is just over a third of my weight) we both sleep well at night. I do a lot less moving in the night and she has stopped kicking me in her sleep so that's good.
