Features

  • Perfect Support and Pressure Relief Experience the ideal balance of comfort and stability. Our hybrid design combines body-hugging support with individually pocketed coils that contour to your body's shape. This targeted support system helps align your spine and relieve pressure points in your shoulders, hips, and back, reducing tossing and turning for deeper sleep.
  • Ultimate Motion Isolation Don't let your partner's movements ruin your rest. Each pocketed coil works independently to absorb motion, preventing it from spreading across the bed. This advanced technology ensures you won't feel a thing when your partner gets in or out of bed, making it the perfect choice for couples and light sleepers.
  • Breathable, Skin-Friendly Comfort Sleep cool and comfortable all night long. The soft, breathable blend of cotton and polyester fabric promotes excellent air circulation, preventing heat from building up. This premium cover is designed to be gentle on your skin while helping to regulate your temperature for a more comfortable sleep environment.
  • Reinforced Edge Support Reclaim your entire sleep surface. We've fortified the perimeter of this mattress with a robust edge support system. This prevents the sagging and "roll-off" feeling common in other mattresses, allowing you to sleep or sit on the edge comfortably and making getting in and out of bed easier.
  • Convenient Box Delivery and Easy Setup Your dream mattress, delivered conveniently. We compress and roll the mattress into a compact box for easy shipping and handling. Simply unbox, unroll, and watch it expand to its full size. It's compatible with most bed frames (platform, slatted, or adjustable bases), so you can start enjoying your rejuvenating sleep in no time.
  • Safety Notice for Unpacking It is imperative to meticulously adhere to the prescribed unpacking procedures to prevent the mattress from undergoing rapid expansion upon exposure to atmospheric conditions, which could potentially lead to forceful impact and consequent injuries.

  • Amazing Mattress!
Size: 12 Queen
I've been sleeping on an old memory foam mattress for 15 years now and my body has definitely begun to feel it, so I've had an eye out for a replacement that wouldn't be too expensive. When this popped up in my offers, I had to jump on it! It came vacuum-sealed and rolled up in a long tall box. It was something of a struggle to drag it into my house, but I managed. The instructions say that it takes at least 24 hours for it to get to full size, but as soon as I'd cut the plastic (using the provided cutter), it expanded to nearly the full size right away! A good thing too, because I was looking forward to sleeping on it that very night. It's what I'd call a medium-firm mattress...it does have some give, but overall, it isn't so plush that you're sinking into it. I love the "reinforced edge support" because the main problem with my old mattress was that, over the years, it had started sinking at the edge, so my body was always subconsciously having to compensate to keep me from rolling towards the edge of the bed. I don't have that problem at all with this one. The motion isolation feature seems to work as well. I'm not currently sharing a bed with another human, but I do have two large cats who like to jump on and off the bed at varying times of the night, but I rarely ever feel them do so. The temperature regulation is nice as well. I rarely wake up feeling overheated (when I do it's usually because one of the previously-mentioned cats has decided to drape themselves on me). I look forward to seeing how this carries through to the summer. The fabric and construction seem of good quality and I like the classy look of the black and grey. There was no chemical smell when unpacking. The queen size fits perfectly on my platform and my mattress topper and sheets all fit nice and snugly as well. Overall, this is a fantastic, quality mattress at a good price. ... show more

  • More firm than a straight foam mattress, great value!
Size: 12 Queen
We've been sleeping on this new mattress for 2 weeks now. I wanted to make sure we had a good number of nights in before writing this review. The mattress came rolled and compressed in a box which was heavy. I was able to handle it myself, but I've also done strength training my entire adult life. You may need assistance. Even if you can handle the weight of the box, it's size makes it unwieldly. If you need to bring it in from the front door or garage and all the way to a bedroom, either a dolly or a friend will make it easier. I opened the compressed roll on top of our existing mattress, thinking it would need a few hours to expand fully. It actually did not need the time. Using the included tool to slice open the plastic wrap, the mattress expanded fully in seconds. Don't stand over it, or it will burst open at you! This mattres is replacing one that is about 10 years old and that was much more expensive when originally purchased. The old one is straight foam with different density layers and has served admirably. This new one is firmer and has what I would describe as air springs. I don't think there are actual metal springs inside. The listing photos and description don't say there are any. Rather, there are sping shaped of circular foam that act like springs. My wife liked the mattress immediately, saying there was less pressure on her hips. It took me a few more days to get used to it and to appreciate the firmness. The outer fabric material seems durable. Our old mattress was also 12 inches deep, so our sheets fit fine. Also, we have an adjustable frame where the head or feet can be raised or lowered as needed. The mattress works fine with the frame. At the time of my ordering, the price was a little over $200 for a queen sized mattress. At this price, I am calling this a great value! ... show more

  • Very good mattress
Size: 12 Queen
Nice looking mattress. Removed and allowed to sit for 3 days per instructions. Very thick mattress once it is completely decompressed. Fits perfectly on queen size box spring. Is very soft to touch and feels great while also being supportive. I would rate it as simi-firm. Looks and feels to be made of good quality materials and the craftsmanship is top notch. The photos are after it sat for 72 hours and then I slept on it. It was a very good night's sleep. ... show more

  • Firm Yet Comfortable Mattress
Size: 12 Queen
I am extremely impressed with this mattress. This was my first time ordering a mattress that comes rolled up in a box, and I honestly wondered how it could possibly expand to full size. As soon as I unrolled it, I could hear it starting to inflate, which was actually pretty interesting to watch. It came with a small cutter to remove the plastic wrap, and within just a few minutes, the mattress began taking shape. It looked almost ready to use right away, but I still waited a couple of days before placing it on my bed, just to be safe. The mattress fit perfectly on my box spring. It sits higher than my old mattress, which I actually like since I’m tall. It gives the bed a nicer height and makes getting in and out easier. The top of the mattress has a plush, textured quilted surface that feels soft, but still supportive. The mattress itself feels firm yet comfortable. It’s not super soft, and it’s not overly hard either so it falls right in the middle. Sitting on it for long periods feels comfortable. It feels like it adapts to my shape. When lying down, it supports my body well and feels like a solid cushion rather than sinking too much. Sleeping on it feels good, and I was able to rest well through the night. The mattress feels supportive without feeling stiff. The edges have a slight bounce and feel supportive enough to sit on without sliding off. Getting on and off the bed is easy, and the mattress holds its shape well. Overall, this feels like a well-structured, supportive, and comfortable mattress that offers both firmness and comfort. I am very happy with this mattress and could easily see myself ordering another one if we need additional mattresses. ... show more
