Twin Mattress in a Box, 8 inch Mattresses for Kids Bed Single Size Daybed Individual Bunk, Memory Foam Medium Firm

Twin Mattress in a Box, 8 inch Mattresses for Kids Bed Single Size Daybed Individual Bunk, Memory Foam Medium Firm

✓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 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.
