- Perfect Pressure Relief & Spinal Alignment. Our memory foam twin mattress combines gel memory foam and zoned pocketed coils to contour your body, evenly distribute weight, and relieve pressure on shoulders, hips, and back. It helps keep your spine properly aligned, reducing tossing and turning for deeper, more restful sleep.
- Ultra Motion Isolation for Undisturbed Sleep. Each pocketed coil works independently to absorb movement, so you wont feel your partner getting in, out, or turning over at night. Ideal for couples, light sleepers, and anyone who wants uninterrupted rest.
- Cooling & Breathable All-Night Comfort. Featuring a breathable, skin friendly knit cover and open cell cooling foam, this mattress enhances airflow, wicks away sweat, and dissipates heat effectively. Stay cool, dry, and comfortable all night long without overheating.
- Strong Edge Support & Full Sleep Surface. Reinforced perimeter coils and high density edge foam prevent sagging and the roll off feeling. You can sleep or sit comfortably right to the edge, maximizing your usable sleep space and making it easier to get in and out of bed.
- Safe Certified & Easy Boxed Set Up. CertiPUR US certified foams are free of harmful chemicals, fiberglass free, and safe for you and your family. The mattress is compressed, rolled, and shipped in a compact box; just unbox, unroll, and let it fully expand within 72 hours. It fits most bed frames and comes with reliable long term support.

Upgraded my son to his first big boy bed.
Size: Twin
This has been a great mattress for upgrading my son to his first twin size, big boy bed. It has both memory foam and also pocket springs, so you get the added comfort of memory foam, but never have to worry about it losing it's shape because of the springs. The springs keep the foam from dipping, sagging or even just not fully expanding in the first place. Which is something I have dealt with in the past. It use to be you had to let memory foam mattresses expand for days to get to their full shape. Sometimes even longer. But when they have springs inside, as soon as you open the compressed package, the springs push open and force the memory foam to expand out. So it's ready to use much sooner. My son's been on this bed for about a week now and he's happy with it. No complaints and because it's 12 inches thick, it would easily work for a full size adult as well. It has plenty of support and when I sit on the side of it, it doesn't sink down at all. So the support goes all the way to the sides. It's a nice mattress!

Decent twin for my light and lean kids
Size: Twin
This mattress is rather surprising. I think its structurally pretty decent for young kids or small adults, but maybe not so ideal for people 180lbs+. We opened this up to let it air out and breathe and the coils on the outside are decent, but the foam on the interior is not as dense as I would expect it to be. I plopped down and my bum touched the floor on the bounce — I am 6’1” 225lbs. My kids? Love it. So I love it too. I can say, leave it out to breathe for a few days and that will help increase the density of the foam.

Comfortable Mattress With Nice Support & Motion Isolation!
Size: Twin
This mattress is surprisingly comfortable for the price and offers a really nice balance between softness and support. The combination of memory foam and individually pocketed springs helps it feel supportive without being overly firm or stiff. The motion isolation works well too, especially for reducing movement transfer compared to traditional spring mattresses. It also provides good pressure relief around the shoulders, hips, and back, making it comfortable for everyday sleeping. The mattress expands nicely after opening, and the medium-firm feel works well for a variety of sleep positions. I also like that it doesn’t have an overwhelming chemical smell during setup like some boxed mattresses do. For the cost, the quality and comfort level are honestly very impressive. Overall, this is a supportive, comfortable, and well-made mattress with good pressure relief, solid motion isolation, and excellent value for the price. Keep in mind that the photos attached are immediately upon unpacking the mattress, and it continued to expand nicely over the next few hours.

Comfortable bed
Size: Twin
I got this mattress for my daughter. Her current one has sagging in the middle of the mattress so when I saw this one I decided to give it a try. It is a 12 inch mattress so it is 2 inches thicker than her old one. It was very easy to open and it popped into shape immediately. It did need a little time to fully come to size, which is to be expected. We put it on her bed and the very next morning she came out and said she had the best sleep of her life. She said the mattress was so comfortable and she slept so good on it. I am very happy and I think it is a great bed for the price at my review. I would definitely recommend it. It is soft and I thought it was comfortable when I laid on it as well.

Comfortable, supportive, and easy to set up
Size: Twin
This mattress was a really nice upgrade from the older one we had been using. It came tightly rolled in the box and was easy to drag into the bedroom by myself, which I appreciated because some mattresses in a box feel like wrestling a dead body up the stairs. Once I cut it open it expanded pretty quickly and was usable that same night, though it kept settling into its full shape over the next day or so. The medium firm feel is honestly spot on. It has that nice contouring you want from memory foam but the pocket springs underneath keep it from feeling like you're sinking into quicksand. Edge support is solid too. I can sit on the side to put shoes on without the whole thing caving in, and there's no weird roll off feeling when you're sleeping near the edge. Motion isolation works well from what I can tell, and it has stayed cool through the night without that sweaty trapped heat some all foam mattresses get. For the price point this is a really good buy. It doesn't feel cheap, the cover is soft, and the build quality seems like it should hold up. My only small note is that it had a bit of that new foam smell for the first day, but it aired out quickly and wasn't anything crazy. If you need a twin that actually feels supportive and not like a glorified yoga mat, this one is worth grabbing.

This mattress is perfect! My son needed a new mattress without breaking the bank so we divided on this one. It’s very comfortable and just what we were looking for

High quality mattress
Size: Twin
I was pleasantly surprised by how comfortable this 12-inch twin mattress in a box turned out to be. It arrived tightly compressed and was super easy to set up—just unbox, unroll, and within a few hours it started taking shape (fully expanded by the next day). The medium-firm feel is a great balance—supportive enough for my back but still soft on top for comfort. I’ve been sleeping much better since switching to this mattress, with no more tossing and turning. It also does a nice job of minimizing motion, which is great if the bed is used by a restless sleeper.
