Features

  • 14 Inch Mattress ConstructionWith Medium Firm firmness, its a great choice for back, side and combination sleepers. The all-foam construction of the Gel Plush mattress is soft and contouring without compromising support. The plush top layers provide lots of pressure relief for achy muscles, joints, and pressure points. It allows your shoulders and hips to fall into the foam, but still follows the curvature of your spine to keep it aligned.
  • A Safe and Hypoallergenic ChoiceTo further implement exceptional design and functionality into the mattress, we used a Fiberglass-Free FR inner cover to replace traditional materials that contain fiberglass to make sure you sleep more at ease; In addition, we used a breathable soft fabric cover that is removable via a zip at the bottom of the mattress, this enables effortless cleaning, keep your mattress fresher and increase mattress life. More, all our mattresses are CertiPUR-US certified.
  • Pressure Relief through Medium FirmnessThe medium feature of our mattress is ideal for every type of sleeper. It contours to every curve of your body, offering a perfect balance of support and pressure relief, regardless of whether you're a side sleeper, back sleeper, stomach sleeper, or someone who frequently changes positions through the night.

  • 6" Memory Foam Mattress (don't know the brand it doesn't say)
Color: White Size: Full Style: 6 Inch
This mattress arrived a week or so ahead of schedule so that was a big plus right there! It took me about 20 minutes to cut through all of the plastic on the mattress, but once that was accomplished, the mattress didn't emit any noticeable odor. It unfolded very easily and is really lightweight. It seemed to be inflated by the time I got it positioned on the bed. This is a 6" memory foam mattress. One side is bumpy so I figured that was the side that was the bottom side. I did take a nap on that side though and didn't mind it at all. I slept very well the first night and thereafter. I notice I am not tossing and turning and seem to fall asleep rather quickly. Those are vast improvements for me. I sleep soundly all night long. The price was only 170.00 so is very affordable. I live in an RV and this mattress satisfies my needs perfectly. I was skeptical when I saw the price, but it got such exceptional reviews by others that I decided to give it a try and am so happy that I did. I'm not opposed to a "bed in a box" as I have purchased them before and prefer it just because of the convenience it offers. I don't know why these are stated as "kids" mattresses, they work just fine for adults. I would recommend this mattress to others. I purchased the firm style, for .18 more you can get the plush style, or at the time I purchased this mattress it was .18 more for the plush style. And another bonus is my cat Pebbles loves it too! So if you vacation or live in an RV this would be a great mattress, great for a guest room or a kids room. ... show more

  • Excellent choice for a mattress
Color: White Size: Full Style: 10 Inch
This matters had no odor and puffed up to a perfect 10 inches, which is the thickness I ordered. It is a perfect medium firm which was recommended to me by my doctor. It is firm but not hard and gives enough squishiness to feel comfy while still supporting my body. I love this and it was so affordable! ... show more

  • Good mattress for RV
Color: White Size: Full Style: 10 Inch
It sleeps cool and is firm when you first lie down but slowly forms to your body. I use it in an RV with no box spring just flat on the bed shelf area and it is comfortable. I would recommend it with a waterproof mattress cover to protect the mattress from humidity RVs tend to have. unpacking was easy and took less time than recommended to expand to full height. Good mattress. ... show more

  • Just Buy It
I read reviews about this and was conflicted whether to purchase or not. I ended up buying two of them and I love them. They are a little firmer than I expected, but in a good way. For free shipping and this price point, they're pretty great.

  • Even the dog is sleeping better.
Color: White Size: Queen Style: 12" Memory Foam
Little stuff: box was awkward. Possibly some reinforced tape around the center of the plastic wrapping, to keep it from breaking the box. Thick, firm, well constructed. It’s much firmer than the mattress it replaced. So, I’m getting used to it. A three month stretch of back pain, is finally improving. I’m not sure how much is attributed to this mattress. ( I used the mattress on top of an old box spring, while waiting for the new frame’s delivery. And, it did help on its own) But, combined with the iDealBed 4i, I have been waking up in pain less often. And, the adjustability, and massage of the frame have greatly improved my ability to get back to “useful” sleep after waking in pain. Bottom line: A near lifetime of back pain is improving. Though, my review is based on nearly a month on the mattress. And, maybe two weeks with the frame. It has also been a period of spring weather changes. From freezing rain to days in the 80’s. Conditions that would traditionally increase pain. I feel definite improvement. Highly recommended. ... show more

  • Perfect mattress for our needs
Color: White Size: Twin Style: 8" Green Tea Memory Foam
We were looking for a shallow twin mattress that would slide under my teenage sons bed for when he has friends sleep over. This mattress checked all our boxes we were looking for. 1. Price was very reasonable 2. Arrived next day 3. Expanded almost completely once unwrapped 4. Surprisingly plush and comfortable. Teenage boy approved 👍🏼 Actually, I think it would be just fine for myself too if ever necessary. When it comes time to replace my master bedroom mattress I would consider ordering again. Why pay 10x more for comparable comfort. ... show more

  • It is just ok
Color: White Size: Full Style: 10 Inch
The product was great but now after almost a year, the wear on the foam is not great. There are soft spots where each person sleeps, even with rotating it. I would say it would be ok for a guest room or a lighter person, but not for every night use in my opinion.
