Main highlights

•【Easy To Clean】: There is a soft cloth cover outside the memory foam mattress. The middle zipper design makes it easy to take off and machine wash. Removable for periodic cleaning, this mattress is composed of breathable cover, 1'' gel memory foam and a 4'' durable high-density base foam layer. Memory foam molds to your body to relieve pressure, giving you the ultimate comfort and rest you need.
•【Comfortable And Breathable】: The high-density base foam layer shapes and conforms to the body, eliminating tossing and turning. The gel memory foam mattress adopts slow rebound memory foam, which can slowly release pressure in a short time and balance the strength. Stress-relieving gel foam naturally draws body heat away for a better night's sleep, and a fine-grained 4-way stretch omnidirectional sleeve works with memory foam to optimize its consistency.
•【CertiPUR US Certification】: High-quality gel memory foam meets the performance and durability standards of the CertiPUR US program, with medium cushioning and hardness, which can make you feel the amazing comfort of floating on the clouds. A healthy spine requires the right gel mattress. Each mattress is CertiPUR US certified free of any harmful substances, allowing you and your child to sleep peacefully.
•【Excellent Quality】: In order to improve the support and heat dissipation effect, the mattress adopts a two-layer full-foam system design, including memory foam and high-density base support foam, which brings ultimate comfort. This gel memory foam mattress is moderately firm, slightly higher than a traditional solid mattress. The gel memory foam mattress supports all parts of the body evenly and independently.
•【General Note】: The mattress is compressed into a strong plastic bag and protected with a cardboard box. When you need to use it, just open the plastic bag and open the mattress. Please allow 24 - 72 hours for your mattress to return to its full shape. Any memory foam will expand faster in a warm room. In colder temperatures, your mattress may take longer to return from its compressed state to its full size upon delivery.
