It’s comfortable. The cool jewel starlight is a luxuriously supportive mattress for cool, conforming sleep. It is designed for a plush feel, which often appeals to side sleepers. The foam layering system is designed to have an initially plush softness on the surface, and luxurious contouring support underneath. It’s cool. Instead of trapping heat like traditional memory foam mattresses, gel memory foam is designed so you can enjoy premium pressure relief without the heat. Gel memory foam delivers a cooler sleeping experience. The foam is also designed, at a cellular level, with an open structure so air can flow freely. It’s supportive. While similar mattresses have a single block of support, we’ve engineered a two-step support system. This two-step support system delivers a progressive, dynamic support so you can wake up refreshed every day. It’s safe. The foam used in this mattress is -us certified, which means the foam has passed an independent safety test for material safety. Rigorous testing has verified no formaldehyde, mercury, cfc’s, dB’s, cfc’s, or prohibited phthalates are used in this mattress. This mattress no zero latex or synthetic latex. Sleep well knowing you’re sleeping safe. It’s durable. We provide an industry standard 10-year against manufacturing defects. It’s easy to setup.
