The natural sleep 2000 provides comfort and support with a reflex foam layer upon a sophisticated spring system containing individually wrapped coils that move independently and are encased in separate pockets, so they can shape precisely to your body and provide consistent distribution of support throughout the mattress and lessens motion transfer for sleep partners. The higher spring count offers greater support and shape to your body more effectively. Reflex foam is made up of tiny holes that slightly adapt to your body shape but bounce back against you at the same time. The high-density foam is naturally hypoallergenic and durable. Flexible and responsive, the natural sleep 2000 mattress provides healthy spine alignment and back support. With a sumptuously soft stretch knit cover and carefully hand-stitched border, you will have a luxuriously sound sleep. Myer Adams Size: Small Single (2'6)
