Three layers are at work to provide you with the optimum level of comfort. First is the extra bouncy high density super soft foam, which provides fluffiness to the mattress. The second is high-density premium PU foam, which provides partial firmness to the human body. The third is the high-density reactive foam, which stiffens the spine. It is a very good combination of reactive foam and PU foam. So, it provides the real pleasure of sleep. This mattress is decorated with high-GSM fabric with beautiful designs and colors.
