Features

  • 90% Polyester, 8% Polyamide and 2% Spandex
  • 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.

    • comfort and quality
Style: 6 inch Size: Twin
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. ... show more

    • Great Mattress
Style: 6 inch Size: Twin
This twin mattress worked out great! It’s comfortable, supportive, and just the right firmness — not too hard, not too soft. Perfect for my child’s bed, and they’ve been sleeping well on it. It also expanded well. For the price, the quality is excellent. Definitely happy with this purchase!

    • Mattress is as expected.
Delivery was early. Packaging was perfect. Mattress unrolled with ease and was fully expanded in just a few hours. No odors at all. Sleeping on the mattress is restful, very comfortable, and the memory foam seems to be alleviating some of my morning stiffness. Quality thus far is five star. Use over time will tell. Queen RV short 10” mattress. Definitely recommend. 73 year old female. ... show more

    • Absolutely Perfect for Me
Style: 10 inch Size: Queen
I bought this to replace a memory foam mattress I had for 15 years. I haven’t been disappointed at all. It’s just as comfortable as my previous much more costly one.
