This memory foam mattress is available in 10-inch and 12-inch heights. It also has four sizes to choose from: Twin, Full, Queen, and King. This mattress is made in Singapore and has been certified by CertiPUR-US. This mattress has a medium firmness. On a scale of 0-10, with 10 being the softest, this mattress would probably be a 6. We used cooling fibers and breathable gel foam in this mattress. We insist on using these materials even though they cost more than ordinary materials. These materials keep people cool while they sleep, making them ideal for someone who sweats easily. This mattress combines individually wrapped coils with multiple layers of memory foam. An independent spring structure is better than a whole spring structure mattress. Your lover won't be easily awakened when you toss and turn during a sleepless night. This mattress has great support. The pressure in each part of the body is different, so we designed 7 zones of support. This mattress curves to fit the contours of your body, reducing pressure points. This helps to maintain the health of the spine to a certain extent. This mattress has reinforced edges and is made with high-density foam. The edges of the mattress should not collapse when you sit on them. We compress the mattress when packing to reduce shipping costs. Leave the mattress cover flat in a ventilated area for 48-72 hours until it has fully expanded.
