The Brighton 6" Gel Memory Foam Mattress is designed with children in mind. Malouf created this memory foam mattress with a slightly less dense top layer of foam while keeping the supportive base that every person needs. Featuring 1.5" of temperature-regulating gel memory foam that conforms to your body while helping diffuse heat while you sleep. The soft, velour cover features a waterproof backing to help prevent spills and stains on the mattress but is made from breathable material to allow airflow. The cover is removable and machine washable. The bottom has a non slip base that grips the mattress foundation to prevent movement.
