Delivered fast than what I am expected (1day) which was great. The mattress works great for me, soft to firm with back supportive. I am a 5’9 and side sleeper, I used to have back pain with all those mattress out there, my previous mattress brings me back pains upon sleeping and awakening. Before I go for those super expensive one, this is my last shot. LET ME TELL YOU WHAT!!! For the past 2 weeks sleeping on this mattress I have not experience any pain. Also a hot sleeper here, and so far so good for the summer in the south. If you’re taking only one thing from this review, here it is: this mattress is game changing, it is not only what was listed but also a lot more. For me it is more than comfortable, it gives me extra support and extra energy. You will never know hoe terrifying I was when I am heading to bed for all the pervious, but then this comes and magic happened. Base on the cost, it is amazing. I absolutely recommend this product.

I’ve had this mattress It’s medium firm, comfortable on my back, and the cooling cover feels nice at night. Sleep has been restful and supportive—I’m looking forward to seeing how it holds up over time. The mattress is very comfortable, with a nice balance between support and softness. It stays cool at night and doesn’t trap heat, which makes sleep much better. I also like that it comes with a long trial period and warranty, so you can buy it with confidence. Overall, a great choice for the price.

From the moment this mattress arrived in its box, I was intrigued. Setting it up was straightforward, and it expanded beautifully. What immediately stood out was the incredible balance of softness and support. It has a delightful medium-firm feel that cradles the body without letting you sink in too far. The initial sensation of lying down is remarkably inviting, creating an instant feeling of relaxation. Having used it for a while now, the cooling aspects have truly impressed me. The cover itself feels cool to the touch, and throughout the night, it genuinely helps regulate temperature, preventing that usual stuffiness. Furthermore, the motion isolation is excellent. Even with a partner or pets shifting around, disturbances are minimal, leading to much more uninterrupted sleep. It truly feels like a personal sleep zone. The combination of the supportive coils and the contouring memory foam provides noticeable pressure relief. I wake up feeling refreshed, with far fewer aches and pains than before. It maintains its shape and comfort consistently, which speaks to its underlying quality. Knowing it’s made with certified, safe materials also adds an extra layer of peace of mind. This mattress has undeniably elevated my sleep experience to a five-star level, proving to be an outstanding foundation for truly restful nights.

This mattress is incredibly comfortable! I bought it for my toddler as part of setting up her “big girl” room, and I was honestly surprised at how nice it feels — I’ve even laid on it myself, and it’s beyond comfortable. The memory foam has a perfect balance of softness and support, and the cooling gel really does help it feel breathable and not overly warm. It arrived well-packaged in a box and expanded to full size very quickly after following the instructions. No weird smells, no waiting days for it to fluff up — it was ready to go in just a short time. I also love that it’s fiberglass-free and CertiPUR-US certified, which gives me extra peace of mind since it’s for my child. The soft knit cooling cover is another nice touch, making the mattress feel even more cozy. At first, I thought the price was a little high for a twin size, but once it arrived and I saw the quality, I understood why. It feels more like a premium mattress than a standard twin, and I know it will last for years as she grows. Overall, this was definitely worth the investment. It’s safe, comfortable, supportive, and feels like a high-end mattress. I’d highly recommend it for anyone looking for a reliable, comfortable twin mattress, especially for kids moving into their first big bed.
