On a scale of 0-10, with 10 indicating the softest, this mattress might be a 6. We used Cool Gel Memory Foam and High Density Memory Foam in this mattress. We adhere to these materials, even though they are more expensive than regular materials. These materials allow you to snuggle up comfortably on this cool, cozy, superbly supportive, and durable mattress, especially for those who tend to sweat. The mattress is made with a non-slip mesh fabric that enhances grip and reduces wobbling. The mattress is also cushioned with individually wrapped springs for good motion isolation and high-density memory foam to help with motion transfer. As a result, your sleep will not be disturbed when your partner's child rolls over or gets out of bed, allowing you to enjoy a restful night's sleep. Meanwhile, the springs in the mattress provide excellent support, and the support coils around the edge of the mattress provide reinforcement. The support of the mattress is long-lasting and durable while also eliminating any pain and stiffness. The mattress is made in Singapore and is CertiPUR certified in the USA. In addition, the rayon of the cool bedspread is OEKO-TEX certified. Wash at 40°C/100°F. Tumble dry low. Do not iron. Do not dry clean.
