The modern M455 smart adjustable base gives you all the benefits of elevated sleep with a few relaxing extras. This linen-inspired upholstered base has built-in Bluetooth® so you can change your sleeping position with the push of a button—on your phone. Or, using the MALOUF™ Base App, you can skip the button altogether and use Siri to adjust your position. Try both preset positions, including Zero Gravity, or customize and save a position of your own. And before you turn in for the night, wind down with a relaxing neck and back massage with three available intensities. Includes backlit wireless remote and a 20-year warranty.
