The Uapev 12-inch Queen mattress has exceeded my expectations. It arrived conveniently in a box and expanded quickly to its full size. The hybrid design with memory foam and individual springs provides the perfect balance of comfort and support. I love how it relieves pressure and minimizes motion transfer, making sleep quiet and undisturbed. It feels soft on top but still firm enough to keep my back supported. Every night I wake up refreshed and well-rested. Highly recommended for anyone looking for quality and comfort at a great value!

I bought this 10-inch mattress for my child’s bed and it’s been a great choice so far. It’s firm enough to give good support but still soft enough for comfort. My child sleeps through the night without complaints, and it fits perfectly with standard sheets. The mattress expanded fully within a few hours after unboxing, and there was only a mild “new mattress” smell that disappeared by the next day. It’s light enough for me to move when changing sheets, and the height is perfect — not too tall, so my child can easily climb in and out of bed. For the price, it feels well made, and I’m confident it will hold up for years of growing. It’s very quiet, no noises while moving! *Bottom Line: A great choice for a child’s room. comfortable, supportive, and budget-friendl. No complaints regarding this mattress.😊

I was a bit skeptical about ordering a mattress online, but the Uapev Full Mattress completely exceeded my expectations. It arrived in a compact box, fully sealed and well-packaged, making it easy to move to my bedroom before unboxing. Within a few hours, it expanded to its full 10-inch thickness, and I was amazed at how plush and supportive it felt right away. The combination of memory foam and individually pocketed springs creates the perfect balance of comfort and firmness, giving me the best sleep I’ve had in years. One of the biggest surprises is how silent and motion-isolating this mattress is. Even with someone else moving beside me, I barely feel any movement, which means no more sleep disturbances. The pressure relief is outstanding—I wake up feeling refreshed with no soreness, and the plush surface adds an extra layer of comfort that makes lying down feel like sinking into a luxurious hotel bed. It’s hard to believe I got this level of quality from a simple Amazon order, but it’s the real deal! If you’re hesitant about buying a mattress in a box, don’t be—this one is legit and worth every penny. The fact that I was able to get a high-end hybrid mattress online without the hassle of furniture stores is incredible. The price is unbeatable for the quality, and the convenience of fast delivery straight to my doorstep makes it even better. If you want plush comfort, excellent support, and a hassle-free buying experience, this mattress is the way to go!

I really love this mattress. I have eternal lower back problems and this mattress really provided support where I need while also allowing me to sleep on my side comfortably which was really important as some mattresses I’ve used in the past have been to firm on the top to sleep on your side whereas this mattress is just enough cushion and support from the springs underneath. The setup was very easy, I just undid the box, it came with a cutter to safely unwrap the plastic without cutting the fabric which I thought was a nice detail for sure. And it immediately puffed up, I was never worried about it not inflating all of the way. There was no gross manufacturing smell or plastic smell, just a light cardboard smell. This mattress doesn’t make me feel hot or sweaty, which is another big thing for me because I get night sweats. I would recommend a mattress protector as it is white and I have black cats so I noticed their hair stuck to the mattress a lot while it was puffing up. The mattress does not squeak which I love, I jumped on it and no noise so that was great. All together I really love this mattress especially for the price, it was true to size and definitely feels like a high quality mattress that will last for a while with my family.

I switched to the Uapev 10-inch hybrid mattress, and ever since my back pain has eased, and my sleep well, it’s actually restful these days. The medium-firm feel hits that sweet spot firm enough to hold my spine aligned, yet soft enough to cradle my shoulders and hips. The hundreds of individual pocketed springs support me evenly from head to toe, while the memory foam layer smooths out pressure points and lets me fall asleep without tossing and turning. Plus, motion isolation means I don’t wake up from every little stretch or shuffle. It’s not a miracle cure, but waking up without that stiff, achy feeling that’s magic.

I will never buy any other kind of mattress again. This mattress was inexpensive, and showed up to my door quickly in a box so small I could not believe that it contained a mattress, however upon removing it from the box, it quickly swelled up to over 10 inches thick. Despite the small size of the box, it was much heavier than I expected, but after it swelled to its unboxed size, I realized it was lighter than what I thought it would be. It is made of numerous layers of high-quality foam, & I have not experienced this high of sleep quality on any other mattress. It isolates your movement, so you will not bother someone sleeping beside you, & provides the perfect amount of support in just the right places, unlike a traditional spring coil mattress. Due to my back injury, I have had extreme difficulty finding a comfortable surface to sleep on, but this mattress is perfect for my sleep comfort needs. Also, the price is unbeatable for any mattress, let alone the perfect mattress.

I was very skeptical about ordering a mattress online! I bought this for our guest room and our older kids LOVE the mattress! They said it’s like sleeping on a cloud! It was super easy to set up, we let it “fluff up” for 24 hours and seriously, we don’t regret buying!
