Features

  • 8% Polyester,92% Cotton
  • General Note: Please allow 24 - 72 hours for your Mattress to regain its full shape. Any memory foam will expand faster in a warmer room. In cold temperature, at delivery, your mattress may take a bit longer to return to full sized from its compressed state.The expansion time of the mattress will vary as per the surrounding.
  • Made in the USA.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.

  • Comfortable and Affordable Twin Mattress – Perfect for Kids and Guests!
Style: 6 inch Size: Twin
I recently purchased the Twin Mattress in a Box (6-inch Memory Foam, Medium Firm) for my child’s bed, and I couldn’t be happier with the quality! The mattress arrived well-packaged and expanded quickly once unboxed. The medium-firm support is just right—it’s soft enough for comfort but firm enough to provide great support for growing kids. The memory foam contours well to the body, ensuring a restful night’s sleep. Despite its 6-inch thickness, it feels incredibly comfortable, making it a great option for daybeds, bunk beds, or guest rooms. Another bonus is that it’s low maintenance and easy to move, which is perfect for small spaces. Overall, this mattress is a fantastic choice for anyone looking for an affordable, durable, and comfortable twin mattress. Highly recommended! ... show more

  • Comfortable, affordable and easy to set up!
Style: 6 inch Size: Twin
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! ... show more

  • Really nice and comfy but not 8 inches
Style: 8 inch Size: Twin
Got this for my daughters new bunk bed and saw that the recommended size was a 6 but I had already purchased a 8. When it came in it only got to 7 inches in 24hrs which is fine for the new bed but not what I expected since i paid extra for 8 and not 6 . It's nice to lay on and my daughter jumping on it does not move the whole bed which is PERFECTION. Overall I am satisfied with the quality of the mattress but as a woman,you know that one extra inch counts. ... show more

  • Comfortable and Great for Kids' Beds!
Style: 6 inch Size: Twin
This 6-inch twin mattress is perfect for my child’s bed! It arrived nicely packed in a box and expanded quickly with no strong odors. The medium-firm memory foam provides just the right amount of support—soft but not too plush, making it great for kids or guest beds. It fits perfectly on a bunk bed, daybed, or single frame, and my child sleeps comfortably on it every night. For the price, the quality is great, and it feels durable. ... show more

I’m really impressed with this 10-inch queen mattress in a box! It arrived quickly, was easy to unbox, and expanded to its full size in no time. The mattress is comfortable, offering the perfect balance of support and softness. It’s firm enough to provide great back support but still has a nice plush feel. It’s also surprisingly lightweight and easy to move, which made setting it up a breeze. For the price, this mattress is a fantastic deal—perfect for anyone looking for a quality mattress without breaking the bank! Highly recommend! ... show more

  • Not terrible
Style: 10 inch Size: Queen
Ultimately, you get what you pay for, but this was better than expected. My house came furnished with a pillow top mattress of unknown age that got to be just completely worn out and was hurting my back. I'm totally broke and can't afford a "real" mattress, and I figured that even the worst cheap new mattress has to be better than one that's totally worn out. It's a bit hard, but definitely vastly improved with a super cheap egg crate style topper. Decent edge strength when sitting up on the side, better than expected for foam. It's weirdly difficult to reposition yourself on this mattress, like instead of being bouncy it sort of sucks you in. Not a bad thing, I easily find a comfortable spot and just don't need to toss and turn. It's just a little weird at first. I love that being not a pillow top, sheets fit very nicely. I don't expect it to last long. Hopefully it will last until my financial situation improves. For now, it's definitely a lot better than an old worn out mattress. My back feels a lot better. If you're as broke as I am and desperately need a mattress, this is a fine choice. But if you're not broke, meh, wouldn't be my first pick. ... show more
