Mattress in a box with premium gel foam+bamboo memory foam, fiberglass-free, 2 sides design cover, and medium firm to extra firm for back pain, low motion transfer. Experience the luxury of high-quality mattresses, and enjoy a deep and restful sleep experience.

The mattress is comfortable enough and popped up to full-size within 24 hours. Unfortunately, that full-size is closer to 6 1/2 than the actual 8 inches that I ordered. I’m used to it on Grindr, but kind of disappointed with Wayfair. I ordered that size in particular because it would fill the gap on my new mattress frame and headboard that I also just bought so now I have an empty 2 inches that I have to stuff with pillows or buy a new extra large, extra firm bolster.. Nick. San Francisco, CA. Mon Oct 12 2026

This mattress is exactly what I needed! I moved into a furnished apartment with a very soft mattress. One night on this firm mattress and my back already feels so much better. I slept like a rock. It was packaged very well, and it was easy to open. It was much heavier than I was expecting (who knew mattresses were heavy?) so keep in mind you might need some help. The instructions say to give it 24-72 hours to be fully expanded, but I slept on it a few hours after I opened it, and it was still great.. Samantha. Usaf Academy, CO. Sun Sep 20 2026

The Rebrilliant 12 inch extra firm hybrid mattress is built for sleepers who need maximum support rather than a plush surface. Individually wrapped pocket coils work alongside a gel memory foam comfort layer, so the body stays level instead of sinking toward the middle of the bed. A seven zone support layout places firmer coils under the hips and lumbar region while easing pressure at the shoulders and legs, which helps reduce the morning stiffness that follows a night on a mattress that gives too much. Stomach sleepers and back sleepers benefit most, because a flatter surface keeps the lower back from bowing. Heavier sleepers get a structure rated for serious weight, with a high density foam rail and border coils holding the perimeter firm so the sides do not collapse when sitting near the edge. The cover is cool to the touch and breathable, pulling heat away from the body instead of trapping it. CertiPUR-US certified foam contains no ozone depleters, heavy metals or formaldehyde, and the mattress contains no fiberglass. The mattress arrives compressed in a single box, expands to full shape within 24 to 72 hours, and fits standard Queen frames, platform beds, slatted bases

Comfort. Anonymous. Sat Sep 26 2026

If adults are sleeping on your mattresses, you probably want to have nylon. Its breathability allows your guests to sleep cooler, so you don't have to worry that they'll wake up in the middle of the night dripping with sweat as they throw off their blankets in exasperation. For adults, comfort is a major factor in bedding. Nylon fabrics usually have a softer and slightly stretchy feel because of their woven construction. This translates into a slightly softer sleeping surface. Comfortable: It's a woven fabric, nylon doesn't have a plastic feel, and it breathes well. It's generally preferred for conference facilities, rescue missions, colleges, and military housing. Complete protection: Our mattresses are also fluid-proof, which means our fabrics protect the inside of the mattress from any fluids that come into contact with it, no matter what those fluids may be.

Good quality and I received the product on time. It is water resistant and that’s what I like about this mattress. Worth the money. Joyce Tan. Aliso Viejo, CA. Sun Oct 04 2026

Great buy for price. Not to firm, not too soft.. Springynurse. Chambersburg, PA. Thu Oct 22 2026

A stretch-knit cover offers extra breathability while two layers of memory foam and highly durable orthopedic support foam work together to bring you a great night’s sleep. The high-quality CertiPUR-US Certified foam is resistant to allergens, mildew, mold, and bacteria which makes this mattress a superior choice when it comes to buying a memory foam mattress.

I bought two of these for a pop-up trundle bed for guest use since it claimed to join into a king size bed. That is a different story. These mattress came vacuum-sealed and expanded to almost full size by the time I got the plastic off. The topper is nice material and can be zipped off for easy cleaning. I gave the mattresses about two days to fully expand and was surprised at how firm they are. Most "firm" mattresses are not very firm; however, I weigh just under 200lbs and I sunk in about a half-inch. It is a soft kind of firm, not a hard, cheap couch kind of firm. My wife laid on the top one and she was equally, pleasantly surprised. That says a lot, coming from her, as she has a bad hip and is very particular when it comes to mattresses. I do not believe you will find a better mattress in this price range and I would even venture that these out-match ones that are much more expensive. Very please with this purchase.. Chris. MI. Fri May 15 2026

Please allow 24 - 72 hours for your mattress to regain its full shape. Any memory foam will expand faster in a warmer room. The expansion time of the mattress will vary as per the surrounding

It is a really good mattress Is not too hard but I’m a very picky person with the mattress and since I purchased it I don’t have any more back pain. Anonymous. Fri Oct 09 2026

Thanks to the breathability of the cold foam, the topper offers a pleasant sleeping environment and good heat insulation. In addition, the mattress topper offers strong support for your body due to the high hardness.

We got a mattress last year and it was super hard. We couldn’t even sleep on it. This topper has made all the difference!! It takes about a day to really unfold and go flat, so just give it some time. The corner straps keep it from slipping off. It’s been awesome, and we love it!!. Jenalee. Salem, UT. Fri Jun 26 2026
