Very comfortable mattress, it makes you think it's perfect, and I'm perfectly fine with that. This inflated up to 12.75" Sure not the entire 13", but I don't think I cared for that small bit... But for some people, size does matter. The mattress itself is very soft, it feels very plus as well in certain areas. I believe the description of medium firm is honestly pretty accurate, although I was hoping it would be just a tad bit firmer. The memory foam contours well to the body, and it has so far bounced back after every night of sleep. The person that's using this tends to sleep on just one side of the mattress, this is by far the softest part of the mattress luckily, and it has bounced back as if nothing happened. The isolation tech they put in this does help with movement, I don't feel the person next to me moving much, unless we're both near the center of the mattress... Once again, nearly perfect, and gives you that illusion, and I'm all for it.

The media could not be loaded. I absolutely love this new mattress—it’s transformed my sleep quality from restless to truly restful. It strikes the perfect balance between support and softness—firm enough to keep my back aligned but cushioned enough for comfort. I no longer wake up with stiffness or sore spots. The motion isolation is excellent too—I don’t feel my partner moving at all during the night. Setup was easy and straightforward. The quality feels premium for the price, and I’m sleeping better than I have in years. If you’re on the fence, go for it—this mattress is absolutely worth it.

We recently purchased the Queen 14-inch Memory Foam Hybrid Mattress for our daughter's new apartment. The mattress arrived well-packaged and expanded almost immediately upon unboxing. We allowed it another day or so to fully settle before testing it further. Overall, the mattress proved to be a bit firmer than we had anticipated. This might be attributed to our previous experience with a fully memory foam mattress, as opposed to this hybrid model which incorporates coils. It's possible that this difference in construction will require some adjustment time to get used to the feel. One notable observation was the edge support. When sitting on the side of the bed, the edge collapses quite easily, and the individual pocket coils can be distinctly felt. While this is a minor concern, we do not believe it will significantly impact the overall use or comfort of the bed for its intended purpose. Despite these points, we believe the mattress will serve its purpose well for our daughter's new apartment

The hybrid structure is excellent. The combination of memory foam and independent pocket springs provides a soft wrapping feeling while also providing sufficient support, truly achieving the goal of "soft but not sagging, hard but not uncomfortable." It is a medium to firm comfort type, and is very stable to sleep on. Whether you sleep on your side, back, or turn over, you can feel that your body is well supported. Its zoned support design is also very considerate, with better pressure relief in the shoulder and hip areas, especially for people like me who have some back problems. After sleeping on it for a few nights in a row, I clearly feel that my waist is not as tight in the morning and recovers faster. The independent spring structure makes the entire bed almost vibration-free. I can't feel my partner turning over at all, so I'm not easily woken up at night and sleep more soundly.

this is a very comfortable mattress. I got this for our guest room but tried it out myself as well. The hybrid material is excellent and I wasn't expecting a spring mattress to be this comfortable. It comes packaged really nicely (rolled up and vacuum-sealed). Was easy to open up and put on our frame (no box spring). No foul odor either, but we did let it air out regardless. This is also very reasonably priced. I would recommend this
