Review: This mattress is one of a kind bargain - This mattress is the best. I love it better than the tempur-pedic mattress I had. It is firm but not to firm when laying on it. It gives you a lot of support, for your back and your neck and legs. The cover that comes over it is really soft. The size is perfect It fits my full bed frame really nice. The material of it seems like good memory foam, it doesn't seem like junk far from it! When I unwrapped it, it only took about 4 hours to fully get to 8inch. But over all the shape the size and the feel of it is really comfortable. It also has no smell. I very much dislike smells, this one doesn't have any. I'd highly recommend this mattress if you like firm but not to firm.
Review: After Trying 3 Other Mattresses, This Is the One! - I am extremely satisfied with this Milli 8-inch Twin Memory Foam Mattress. I say that because I actually tried three different brands of 8-inch twin mattresses for my child before purchasing this one, and this was the only mattress that truly met my expectations. One of the biggest issues I had with the other mattresses was sizing. They either didn’t fully expand or didn’t match the advertised dimensions. This mattress, however, expanded properly and reached the correct size. It fit perfectly and looked exactly as expected. The quality is excellent. I occasionally co-sleep with my daughter, and I was pleasantly surprised by how supportive this mattress is. It doesn’t sink excessively under my weight or create that “rolling toward the middle” feeling. It has a great balance of firmness and comfort—firm enough to provide proper support, yet soft enough to sleep comfortably through the night. In fact, I feel like my sleep quality has improved when I co-sleep with my daughter on this mattress. I don’t wake up with back pain, and after using it for several months, it has held up really well. The durability has been excellent, and it still feels just as supportive as when we first got it. Like most memory foam mattresses, it can run a bit warm at times, but I honestly think that’s fairly common with this type of mattress and wasn’t a deal breaker for me. The packaging and delivery were both great, and the mattress arrived in excellent condition. I also appreciate that it’s designed with kids in mind and uses safer materials, which gives me extra peace of mind. I trust this brand much more after this experience. What really stood out to me is that I had already gone through the hassle of ordering and returning three other mattresses before finding this one. Returning mattresses is not easy, so discovering a product that actually lived up to its description was such a relief. Overall, this mattress offers fantastic quality at an affordable price. If you’re looking for a twin mattress for your child—or one that’s comfortable enough for occasional co-sleeping—I highly recommend this one. It has been a wonderful purchase for our family.

## Features

- Unparalleled Quality Control – You can rest easy knowing your mattress is made with high standards and eco-conscious practices. Our global production includes U.S.-based and overseas factories for consistent quality. More than 90% of mattress orders are fulfilled by our U.S. factories. Wake up feeling refreshed every morning.
- Medium-Firm Feel - medium-firm is supportive for most body types and sleep positions. Too-soft mattresses don’t give proper support and can cause back problems in the long run. Too-hard mattresses don’t provide pressure point relief. The sweet point is our medium-firm (6-7 out of 10 on the firmness level scale) mattress strikes the right balance between comfort and support and promotes better sleep.
- Gel Infused - our foam is infused with a cooling gel that helps in dissipating heat, allowing you to sleep cool while retaining memory foam’s original body-conforming and pressure-relieving features.
- CertiPUR-US Certified - all foam used in our mattresses are made without ozone depleters and maintain CertiPUR-US Safety Standards of textile articles at all stages of production. It will have minimal off-gassing, or “new mattress” smell when brought into your home.
- Fiberglass-Free FR Inner Cover - the rib fabric, 92% Cotton, 8% Polyester, provides a safe, effective flame retardant layer around our mattresses, without the negative aspects of fiberglass and other fire-retardant chemicals. No skin irritation, no breathing problems, and no health risks for you and your family — so you can truly rest easy at night.
- Ready for Instant Enjoyment - compressed into one box that is easily shipped and maneuvered into the bedroom. Simply unbox, unroll and this mattress does the rest, expanding to its original shape within 2 hours.
