Features
- Imagine Your Spine Cradles in Perfect Harmony: Our King mattress features a patented 7-zone pocket spring system where coils in the lumbar region are calibrated to be 30% firmer, providing a supportive lift that eases lower back tension, while shoulder and knee zones gently yield for pressure-free comfort. This isnt just support; its intelligent support that adapts to your bodys map.
- Dive Into a Cloud of Breathable: Gel-infused memory foam that rests atop the springs. As you lie down, youll feel it slowly contour to your curves, dissipating heat through capillary-like gel beads. This dual-action layer doesnt just cushion; it actively cools and cradles, turning your King mattress into a personal climate zone for restorative sleep.
- Experience the Quiet Revolution of Independent Motion Isolation: Each spring is encased in its own fabric pocket, moving solo. When your partner turns or gets up, the movement is absorbed right at the source. Youll feel as undisturbed as if sleeping on a separate surface, guaranteeing that deep sleep isnt a negotiation but a guarantee for both.
- Rediscover the Entire Edge of Your Bed: A high-density foam encasement wraps around the perimeter like a supportive frame, creating a stable, sitting-friendly edge that resists sagging even under pressure. This robust border extends your usable sleep surface by nearly 20%, offering freedom to sleep or sit anywhere with confidence.
- We Stand by the Enduring Quality of Every Component:From the tempered steel of the springs to the CertiPUR-US certified foams, each material is selected for longevity. Backed by a 10-year limited warranty, this investment is engineered to provide unwavering night-after-night support, ensuring your sanctuary remains uncompromised for years to come.

I was very hesitant about getting a mattress I couldn’t test out before hand and getting it off line but I am so glad I did. My previous mattress was a $3000 purple mattress and I hated it from basically day 1. This mattress is so perfect and comfortable if you need soft support. And the price is a steal!! Packaging was very minor with damage on the outside and no issue on the inside. Set up was easy. I was impressed with how quickly “inflation” happened. No odor. I love climbing in my cold sheets every night!

I love this mattress!!! It is bouncy and it feels sooooo good on your back. I told my daughter every time I go in my bed it feels like a water bed haha not it just feels great! I got the queen 12 inches. My daughter now wants the exact same one for her twin bed and I will definitely be getting it for her. The quality is amazing to say the least so worth the $ invested in this.

I got the 12-in and the 14-in for my girls. I should have waited to order my own until I tried theirs. The 14 in certainly has more support and keeps its shape much better. Higher quality of sleep for sure. The 12 in is still comfortable but it's noticeably softer. Definitely solid quality.

Love how comfortable it is and was delivered on time. I opened it and left it laying on the carpet for 24 hours before putting it on the bed and sleeping on it.

The media could not be loaded. I was skeptical based on the price and the reviews I read from others, but now that I have my own, here are my thoughts after the first day. There is nothing more satisfying than puncturing a hole in a vacuum seal, especially one this size. It definitely scratched that itch listening to it suck in the air and expand. Okay, aside from my weird obsession with that. The mattress has a good amount of weight. Comparing the old one to the new one, the old mattress was about 8 inches thick, while this one is 12 inches thick. This was before it fully expanded to its natural shape after being vacuum sealed, which normally happens within 24 hours. In the video, I was trying to show how the springs run from the bottom of the mattress to the top. This was about 10 minutes after removing it from the vacuum seal while I was putting a waterproof cover on it. About two hours later, I sat and laid on it, and you do not feel the springs. It is quiet and a little on the firmer side. I would describe it as medium firm. The edges of the bed feel a little weak with the springs, but that is just nitpicking at this point. For the quality so far, I would say it is a good, cost effective mattress. If it had a bit more foam or gel or whatever mixture they use, I would probably give it another star. Long term use is still to be seen in terms of how well it holds up.

I received it earlier than expected and I’m so happy about that! The bed is perfect and soft. Was very easy to handle and very worth the buy!

I got the 12 inch and this is the most comfortable mattress I have ever slept on. After breaking that air tight seal it almost immediately puffed up to 10 inches (which was extremely satisfying for some reason, like someone else said) I left it alone for 12 hours and then slept on it that night. It is firm but also soft. I have not noticed the cooling effect of it yet, but it’s also not summer and it could be the sheets I have on it. The only downside is there is NO edge support at all and it’s one sided so you can’t flip it, you can only turn it 180 degrees. It’s also worth mentioning that for the time being this new mattress is on my old box spring and it is still crazy comfortable. I had a hard time getting out of bed before… now I never want to get up.
