    • Gets softer

      The thinner the mattress the softer it will get. We have the 11" in our gest room for 2 years now and the 9 inch for just under a year in our master bedroom, both medium firmness. But the 11" is more like a medium firm, while the 9" was more firm when purchased and is now very soft. Especially on the one side that gets used more often as the hubby travels, so on my side the foam seems to have almost collapsed/condensed down. So if you like a very soft mattress this is for you, or if it will only be a guest mattress used every so often I recommend it. The price is great and it is comfortable and yes it does run a little warmer then a regular spring mattress, I had to add a cotton mattress cover to get that layer between us and the foam. I'm considering replacing it since when we turn it the hubby gets the soft side and complains about his back, so we will probably go with the 10" mattress next time, since these seem to soften up the more density the better firmness, but we have a vintage mid century bed that requires a low mattress otherwise it covers the low headboard. On the other hand I almost have to climb into the bed with the 11" mattress on a traditional box spring and I'm 5'4"... I hope this helps!

    • LOVE this mattress!

      I love this mattress! I got the medium firm and I haven't slept better in all my life! I don't toss and turn as much and it is so comfortable! I love that there is no motion transfer either. I highly recommend this mattress to you. The delivery was reliable, simple and easily trackable. What a pleasant buying experience! You should "air out" the mattress for a few days before use and it smells a bit.

    • Completely Satisfied, Would Reocommend

      Excellent product. I wanted to wait a bit to write a review to see how well my body adjusted over a few weeks time. My sleep is sound and I wake with no lower back pain as previous experienced with a regular mattress. This is a brilliant choice and you can't beat the price for how comfortable it is. Completely satisfied. I read other reviews that mentioned a slight smell from the bed, I experienced a slight smell as well that dissipated after a day or two.

    • Very Pleased With Purchase

      Mattress was received very quickly. Unpackaged it and allowed it to sit for a few days to take shape. This mattress did not produce a bad smell as it was taking shape. Once the mattress took shape, it was made and since that day, I have slept comfortably and uninterrupted. This is my first experience sleeping on a foam mattress so I have no comparison, but what i can say is that this mattress is a great buy and is extremely comfortable. Will recommend this mattress to anybody.

    • Sleeping better than ever

      I don't sleep well. I can fall asleep, but toss and turn usually. I used to have a comfy pillow-top, but still had issues. Since I got this mattress I can actually sleep without tossing and turning; I get more solid sleep than I'm used to. My back is feeling a lot better as well. I would recommend this product to anyone with joint problems or frequent back aches.

    • So Worth It!!

      Ok, I was skeptical about buying a mattress online, mainly because it was so much money and there are no returns. So I went ahead and bought a King size 9in memory foam-med firmness. Unlike the horror stories, There was no odor, and it re-expanded overnight after unpackaging. i have to say i was impressed. i'm a larger guy and my wife is petite, but both of us are able to get a great night's sleep. after a month of use i am still very pleased. Definitly a bargain!

    • Best sleep we've ever had!

      I would recommend this mattress to anyone looking for medium firmness. We purchased the King size and have been sleeping on it for a year now with absolutely no complaints until it comes to cleaning it. The mattress is extremely heavy and there is a protective layer around the mattress that unzips so you can take it off to clean - this is a two person job getting it off and back on. We've had no issues finding sheets to fit, we get organic sheets from Target and they fit perfectly! We will be getting a box spring soon because the mattress isn't tall enough for our bed frame, so I will repost later if the firmness or feel changes any.

    • Great buy!

      I ordered this mattress as a replacement for our queen that was destroyed in a flood. It came very quickly, was a great price and light enough for me and my friend (2 slight women) to carry out of and into a house. I left it unwrapped in the bedroom and it was it's full size in 2 days, a light odor lasted for a week but it was not unpleasant or overwhelming. It has been 9 months and I love this mattress. We ordered the King because we wanted space and room for the dogs/cats and children. It is soooo comfortable, I feel nothing when multiple bodies are jumping and tumbling on the bed and my back feels great. I recommend this mattress highly, it has met all my expectations.

    • Best Decision

      We have been through 4 matresses in the past 4 years. The traditional mattress was too soft for me and too hard for my spouse. We went with a pillow tip mattress and it was too warm and soft for both of us. We went with an air mattress. That provided a level of comfort, but if we rolled over, one side was significantly higher. Like rolling downhill. It also, after a year, started leaking. The auto airpump would kick on in the middle of the night. HELLO. This foam mattress has been great for both of us. Good support, comfortable feel for both body types.

    • Love, love, love it

      I've been sleeping on this for a little over 2 weeks now and it is truly wonderful. I got the "medium" firmness. I can't believe the difference in my sleep quality -- I don't get as overheated as I did with my old mattress either. I highly recommend it.
