Twin Mattress in a Box, 6 Inch Mattresses for Kids Bed Single Size Daybed Individual Bunk, Memory Foam Medium Firm

  • 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.

I bought this mattress for my kid's bed and it's turned out to be a great choice. It's got a medium-firm feel that gives solid support but is still comfy to sleep on. It fully expanded within a few hours, and I noticed almost no smell after unpackaging. For a 5-inch mattress, the quality is surprising, and it fits perfectly on a bunk or daybed. Pros: comfy yet supportive, lightweight, simple to set up, made in the USA. Cons: it's a bit on the thinner side, so it might not be the best option for adults looking for something plush.

Found the Right Mattress for My Kid

I'm really happy with the Milli 8-inch Twin Memory Foam Mattress. I had tried three other brands for my child and none of them matched up to this one. The sizing issues I faced with the other mattresses were frustrating; they didn’t expand right or just didn’t fit as advertised. But this one expanded perfectly and fit just right. The quality is great! Sometimes I co-sleep with my daughter, and I was surprised by how supportive this mattress is. It doesn’t sag under me or make us roll toward the middle; it balances firmness and comfort well. I've noticed my sleep has gotten better with this mattress. I wake up without back pain, and after using it for a few months, it still feels just as supportive as the day we got it. Yes, it does get a bit warm sometimes, but that’s pretty normal for memory foam and isn’t a big issue for me. The delivery was smooth, and the mattress came in shape. I also like that it’s made with kids in mind and safer materials, which is a big plus for me. After all the trouble with the other mattress returns, finding one that works as promised was such a relief! All in all, this mattress packs in quality for a good price. If you need a twin mattress for your child or for some co-sleeping, I’d recommend this one. It's been a great buy for us!

Easy Setup and Super Comfortable for Kids

I got two of the 6-inch twin mattresses for my kids’ new bunk bed, and they’ve worked out perfectly. Setting them up was a breeze—just took them out of the box, opened the vacuum-sealed bag, and gave them time to expand. Within about two hours, both mattresses were fully shaped and ready to use. They fit the bunk bed just right, and the medium-firm comfort seems ideal for kids. My little ones have been sleeping on them happily with no complaints at all. The quality feels pretty good for what I paid, and they keep their shape well after expanding. All in all, these are a fantastic choice if you’re looking for a simple, comfy mattress for kids. I'm pleased with this purchase.

Great Mattress for My Double Bed

I wanted a mattress for my double bed that I can turn into a larger setup, and this 5-inch one fits the bill perfectly. It's got a nice mix of comfort and support—soft enough to sleep on, but firm enough to avoid sagging or feeling weak. The memory foam shapes nicely to your body, providing solid lumbar support, making it great for regular use. Setting it up was a breeze; it opened up fast with no strong smell at all. The size and thickness are just right for a double-to-large bed arrangement, and I'm really pleased with this comfortable mattress.

Great Mattress for My Double Bed

I needed a mattress for my double bed, which I sometimes make larger, and this 5-inch one has been perfect for that. It strikes a nice balance between comfort and support—soft enough for a good night's sleep but still firm and sturdy so it doesn’t sag at all. The memory foam conforms well to my body, offering solid lumbar support, making it great for daily use. Setting it up was a breeze; it expanded quickly right out of the box, and there was no unpleasant smell. The size and thickness are just right for transitioning my double bed into a larger setup. Overall, I’m pleased with this comfortable mattress.

No odor at all!

I just got two of these mattresses for my kids, and they’re quite comfy. There’s no smell at all, which is a big plus. The kids find them really cozy. They aren’t thick, which makes them great for bunk beds since they don’t stick up too high past the railing. They puffed up pretty quickly—around 30 minutes to an hour, I’d say. Excuse the mess on the bed, but it’s a nice fit and a good size for preteens.

Great mattress for kids!

This is a solid mattress for a child. It fluffed up immediately and had no weird smell. We gave it a day to air out, but honestly, it was good to go as soon as we took it out of the package. It's nice and has the right amount of firmness.
