Customized comfort at your fingertips! We’ve paired the stylish Leggett & Platt S-Cape adjustable base with the luxurious Novaform 12-inch Serafina LP Adjustable Gel-Memory Foam Mattress to give you the optimal combination of relaxation and individualized comfort. Whether you are sleeping, lounging, or working in your bed, you’ll enjoy the pressure-relieving comfort of memory foam adjusted to the position that is just right for you.

Personalize your comfort with the touch of a button.   With the back lit wireless remote, you’re in charge! Head, feet, up, down, a little massage, no massage. Your wireless, programmable remote can take you and your adjustable mattress to an infinite number of positions, including zero gravity to ease the stress on your back and to increase circulation.  The Leggett & Platt S-Cape adjustable base features dual-zone massage with wave technology for a full body massage that loosens up the shoulders and unburdens the legs. The Whisper Quiet motor lifts and reclines smoothly and quietly, while the Wallhugger technology keeps your nightstand within easy reach.
