Product Description:

The Simmons Beautyrest Anniversary Keegan Plush Firm Mattress is inviting to the eyes and welcoming to the touch. This elegant Beautyrest mattress rises from the edges to a lush, tufted top with neatly tailored edging. It reflects the maker's craft in every aspect, such as the hard-wearing top material with a subtle, slightly raised pattern. The mattress has a firm seating edge, and this feature ensures a maximum sleeping surface. The top material completely encases the plush foam top; it combines with a strong core to provide an excellent balance of soft comfort and firm body support. In the tradition of Beautyrest mattresses, this model has high-quality materials and superior construction. It has been built to provide years of excellent service. It provides consistent support across the entire sleeping area to the firm seating edges. It offers consistent support for the neck, back, and joints. The pocketed coils reduce motion and provide a stable sleeping area to minimize sleep disturbing movement. It is designed to fit the contours of the body and promote deep, restful sleep.
