Yes feels great, get a good night's sleep
Reviewed in the United States on May 9, 2026 by cmf9ferrell
Really nice quality and comfortable for our guest room. Unpacking was easy, with my daughter and husband doing the muscle part of moving the box into the BR for set up. It fits the old frame nicely, and we left the box spring under the new mattress for a little more height. The sale price made this the best bedding decision we've made in decades!

nice mattress. great quality

I have been really impressed with this mattress so far. It expanded quickly after unboxing and had very little smell, which I appreciated. The medium firm feel is exactly what I was hoping for, supportive without feeling hard, and it has been comfortable for both side and back sleeping. I tend to wake up easily when someone else moves, and the motion isolation has made a noticeable difference, since movement on the other side does not travel across the bed. The cooling foam has also been a pleasant surprise. I usually sleep warm, but this mattress stays comfortable through the night without that trapped heat feeling. It feels well made and supportive across the entire surface, not just the center, and my back feels better in the mornings than it did with our previous mattress. For the price, this feels like a solid upgrade and something I am genuinely happy we chose.

I recently got this hybrid spring mattress and have been using it for a while. Overall, I am very satisfied with it. The mattress arrived compressed, which made it easy to carry. After unpacking and laying it out, it took about a day to fully expand and fit perfectly on my bed frame. The medium-firm feel is just right for me, providing solid support without being too hard. The memory foam layer on top is very comfortable and contours nicely to my body, so my shoulders and lower back do not feel any pressure while sleeping. What I like most is the cooling effect. The knit fabric combined with the cooling memory foam keeps the surface breathable all night. Even in summer with the air conditioning on, it never feels too hot or too cold. The pocket spring support works really well. When I turn over or get up, the mattress only moves slightly and does not disturb my partner, which really shows the benefit of individually wrapped springs. The mattress is also very versatile for different sleeping positions. I alternate between side and back sleeping, and both my shoulders and lower back get proper support. Even after lying down for a long time, I do not feel uncomfortable. Overall, this mattress balances comfort and support very well and has noticeably improved my sleep quality.

Originally this was supposed to be a "memory foam for twin XL" without even a picture which I expected to be a memory foam topper, but actually ended up being an entire twin XL mattress. Not exactly what I was expecting, and it does make a bit of a hassle now to get rid of the old mattress, but I am quite happy with a complete replacement mattress. The new mattress arrived extremely compactly rolled into a solid 55lb pillar. Was quite shocking how fast it restored its shape once unpacked. Feels very firm on the bottom due to the steel springs embedded inside, but with a very thick foam layer on top so that you can't feel them. This type of mattress is supposed to be very good for back pain. Got this set up and aligned next to my other twin XL, a sort of makeshift king mattress. Slept really well on it and felt no discomfort or anything.

I was looking for a mattress that could balance comfort and support, and this 12-inch medium-firm hybrid mattress exceeded my expectations. The cooling memory foam really works—I no longer wake up sweaty, even during warmer nights. The breathable knit fabric adds to the comfort, making the sleep environment feel fresh and cool. The hybrid design is perfect. The foam layers give me that plush, contouring feel, while the pocket springs provide solid support without being too firm. It’s the ideal balance for me as a side sleeper, but I’ve also tried sleeping on my back and stomach, and it feels great in all positions. One of the biggest wins is motion isolation. My partner moves a lot at night, and with our old mattress, I felt every toss and turn. With this one, I barely notice any movement—it’s like sleeping alone in terms of peace and quiet. Setup was super easy. It came compressed and rolled in a box, and within 48 hours, it expanded fully. Plus, the 100-night trial and 10-year warranty gave me peace of mind, but honestly, I knew after the first week that I was keeping it.

It’s been a really solid upgrade from my old one. The cooling memory foam is noticeable right away. It doesn’t trap heat like traditional foam, and the breathable fabric helps keep things comfortable through the night, even if you tend to sleep warm. The hybrid design is what really makes the difference. The combination of pocket springs and foam layers gives a nice balance between softness and support. It feels plush on top but still supportive underneath, so you don’t sink in too deeply. I mostly sleep on my side, but it’s also comfortable when I switch to my back. Motion isolation is another big plus. My partner moves around a lot at night, and I barely feel it. Overall, this mattress offers great comfort, good temperature control, and reliable support. I wake up feeling more rested and without that stiff feeling I used to have.
