For over 30 years, Purple has devised its own technology to provide better support and comfort for people sleeping. Known for its famous grid-cushioned mattresses, Purple incorporated research and technology aimed to deliver maximum comfort and instant adaptive support while you are sleeping. The GelFlex Grid, a super-stretchy material in each of their mattresses, instantly adapts to your body and cradles your pressure points, balancing comfort and support. Its support is so effective that it is used in hospital beds for critical patients across the United States. The GelFlex material effortlessly stretches and springs back, ensuring durability for each mattress.
