Features
- Warm TipsSince the mattress is packed in vacuum rolls, it is highly compressed, vacuum-sealed and neatly rolled in a box. It is compact and easy to carry. It will expand slowly when unpacked. Please leave it idle for 48-72 hours to wait for it to fully expand for the best effect.
- Steady EdgeThis mattress features triple-reinforced perimeter springs to prevent sagging and sliding, ensuring comfort throughout the bed. You can sit or sleep near the edge of the bed with peace of mind - no rolling or instability. Perfect for restless sleepers, couples, or those who share this special mattress with others.
- Motion Isolation & Noiseless DesignIndependently wrapped springs and dynamic transition foam absorb 95% of motion transfer, so your partner's movements won't disturb your sleep. The layered foam structure minimizes noise in the mattress, creating a peaceful environment so you can sleep deeply and undisturbed night after night.
- Pressure Relief, Suitable for All Sleeping StylesThis mattress has a medium firmness that can seamlessly adapt to back, side or stomach sleepers. Hundreds of responsive springs conform to your curves to reduce pressure points. The memory foam top layer can effectively support joints, and the healthy material ensures safety and durability, providing years of support.

Very comfortable! Sent this to my son for his guest room prior to my visit. Easy delivery and set up. Looks like good quality and it is very supportive and cozy. Had no back issues in the morning - first time in a long time. I’d buy this again.

This mattress has been a life saver for my back/body. I look forward to sleep now that I am not waking up in more pain than when I went to bed. It is a nice thickness and super comfortable!

Bought for our RV (5’4”, 120Lbs & 6’1”, 180 Lbs). Have had for a few weeks. We threw-on a 1.5” memory foam topper (slight spring feeling) and a thin gel-type mattress cover. Very happy with this mattress. Highly recommend - at least if ur in our weight range. Weighs ~75 Lbs. Edge springs definitely keep u in the bed, but r not stiff enough for us to feel them - just right. Sitting on or rolling off the edge still flattens the edge, but in a good way and not uncomfortable. We’d classify the inside coils as Medium-Soft rather than a Medium-Firm, but we very much like the support and comfort for sleeping (with the memory foam topper and gel-type cover). We didn’t experience the “spring isolation” the product’s video shows, but we love this mattress and highly recommend it for people around our weights. Will need to wait to see how durable the springs r to sed how durable it is. We feel its initial quality is high and although the price may seem low, its a great product.

This replaced a $2000 Serta. It’s very comfortable and fits to your body. My wife loves it and says it’s the most comfortable mattress she’s ever slept on.

this mattress is soft, whilst unboxing it it did not blow up in my face like i thought it would! (1st time unboxing a mattress in a box) definitely worth the 120$ i spent.

This mattress is one of the worst I have ever used. It is advertised as medium firm, but it feels extremely hard and uncomfortably bumpy. I switched from an extra firm mattress with a foam topper, hoping for a bit more softness, but this mattress turned out to be worse than my previous one. The bumpiness is especially problematic; there’s no way to adjust and find a comfortable spot. Everywhere I move, I encounter a hard bump, and it feels like a large, pointy rock with each bump. It’s awful, and I hardly slept at all. The pain was so intense that I had to go to sleep in my recliner chair.
