Product Description:

The Simmons Beautyrest Anniversary Keegan Extra Firm Mattress provides a solid sleep area, and the design promotes a deep and restful sleep experience. This well-made and thoughtfully crafted Beautyrest mattress has a stable edge-to-edge sleep surface with a firm seating edge area. The seating area minimizes movement across the sleeping area. It offers an excellent balance between a soft, plush top and a firm and solid internal support system. Encased by special edging material, the foam top has remarkable styling. This luxurious top material and eye-catching design make an appealing, distinctive image. This strong and durable Beautyrest mattress has an advanced system of pocketed coils designed for many years of excellent performance. This permits each coil to act separately, and it minimizes unwanted motion. This coil system maintains consistent pressure to support the spine and joints, and it adjusts tension to fit the contours of the body.
