I chose this 10-inch Queen mattress for my daughter, and it was just the right size. This mattress uses a combination of gel memory foam and springs to provide a comfortable and peaceful sleeping experience. My child likes it very much. It is not too soft or too hard, and the fabric is soft and skin-friendly. There is no odor when unpacking and it expands quickly. The support performance is very good. It is worth the money. I highly recommend it. I left it for 24 hours before using it.

I bought the queen size version of this 12-inch hybrid memory foam mattress, and I’m genuinely shocked by how much I love it. The hybrid design gives it amazing support — the coils add just the right amount of bounce while the memory foam absorbs movement so well that I barely feel my partner next to me. When I first tried it, I thought it might be a little too firm, but after sleeping on it, it turned out to be the most comfortable mattress I’ve ever owned! I’m a combination side and back sleeper, and I wake up without any pain for the first time in forever. My partner sleeps on his stomach and it works great for him too. I also tend to sleep really hot, but this mattress has a cooling feel that’s made a huge difference. It did take about 24 hours to fully expand, but it did reach the full 12-inch height, and I was able to sleep on it the very first night with no issues. Another major plus — there was absolutely no odor when I opened it. After a month of using it, I’m super impressed with the quality and support. It feels well-made and durable, and I can tell it’s going to last. For the price I paid, I honestly can’t believe what a good deal it was. I’m pretty picky about mattresses, and this one exceeded every expectation. Highly recommend!

I love this mattress! It is so comfortable, right amount of functual support for my bad back and still soft enough for easy sleeping with out pressure points. I want to replace all my kids mattresses with this one. So glad I picked this brand. I got the full size, it was packaged exclent and when unwrapped with the provited tool it expanded as expected. No weird smell, looks nice, no rips or stains or odd lumps. Highly reccomend this brand of hybred memory foam bed in a box!

Such a comfortable mattress! It plumped up quickly and is the perfect medium firm. While the sides do give a little it is forgivable considering the price and the quality! Would buy again!
