Features
- Unparalleled Quality Control - you can rest easy knowing your new mattress was created with high manufacturing standards and environmentally conscious practices. Get a good night's sleep every single night and wake up feeling refreshed and ready for the day.
- Medium-Firm Feel - medium-firm is supportive for most body types and sleep positions. Too-soft mattresses dont give proper support and can cause back problems in the long run. Too-hard mattresses dont 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 foams 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.

When the box showed up at my front door, I was kind of surprised at how small it was. I didn’t think a whole mattress could fit in there! It was packed up really tight, but once I cut the plastic and unrolled it, it started growing like magic. It took just a few hours to fully puff up, and it looked way better than I expected. Sleeping on it has been awesome so far. It’s not too soft and not too hard—it’s just right. I got it for my little brother’s bunk bed, but I tried it first and honestly, it’s super comfy. He sleeps through the night without waking up now, which is amazing. Even when I sit on the edge, it doesn't squish down too much. The best part is how easy it was to carry upstairs. Since it came in a box, I didn’t need help getting it to his room. I also liked how clean and fresh it smelled—no strong odors or anything weird. It fit perfectly in the bed frame and didn’t need any extra tools or pieces to set up. One thing I noticed is that it’s a bit thinner than regular mattresses, so you might want to use a thick blanket underneath if your bed frame has big gaps. Also, it doesn’t come with a cover, so you’ll need to buy one. But overall, it’s a really good buy and I’d totally recommend it to anyone needing a mattress for a kid or guest bed.

I purchased the 6-inch Twin Mattress in a Box for my child’s bunk bed, and I’m thoroughly impressed! It arrived quickly and was super easy to unbox and set up—just unroll and let it expand. Within a few hours, it was fully fluffed and ready to use. The medium firm memory foam provides just the right balance of comfort and support. My child sleeps through the night without tossing and turning, and I even tried it out myself—it’s surprisingly comfortable for a thinner mattress! It’s the perfect fit for a daybed, bunk bed, or any small space where you need a quality mattress without breaking the bank. No weird odors, no lumps, just a great value for the price. Highly recommend this for kids, guests, or even a dorm room setup.

Perfect for on-floor sleeping by my grandson, and for a daybed in the future. Very comfortable. Fits under the full-size bed for storage until needed.

Good mattress. You take them right out of the box and they inflate pretty quickly maybe took an hour to be completely full. They are for my kids and they both seem to love them. I do feel that they are a little hard (just my preference) but otherwise very comfy! And also good quality and non toxic which is why I chose them!

I was skeptical about ordering a mattress in a box, but this 6-inch mattress has completely won me over! From the moment it arrived, everything about it exceeded my expectations. The mattress arrived in a compact box, making it super easy to maneuver into my bedroom. Once unboxed, it quickly expanded to its full size within a few hours, though I let it sit overnight as recommended. There was minimal odor, which aired out completely by the next day. For a 6-inch mattress, the comfort is amazing! It has the perfect balance of softness and support. I’ve used it on a platform bed frame, and it provides excellent support without feeling too firm. I was worried it might be too thin, but it holds up great for both sleeping and sitting. The construction feels solid, and the stitching and cover are high-quality. Despite being an affordable option, it doesn’t feel cheap at all. After several weeks of use, there’s no sagging, and it continues to provide restful sleep every night. This mattress is perfect for guest rooms, kids, or anyone who wants a budget-friendly yet comfortable sleeping option. It’s lightweight, easy to handle, and ideal for tight spaces. I highly recommend it to anyone looking for a no-fuss, high-value mattress!

I recently purchased the 6-inch twin mattress for my child's bed, and it's been a great choice! It arrived quickly, was easy to unbox, and expanded to full size within hours. The memory foam offers a perfect balance of comfort and support—medium firm, just as described. My child sleeps soundly through the night now. Great quality at an affordable price—highly recommend!

Pleasantly surprised. I didn't think this was going to go over well. The mattress is firm but comfortable, and I usually like super soft. My guests thought it was comfortable as well.
