The M555 Adjustable Bed Base takes relaxation to the next level. With five preset positions (Zero Gravity, Anti Snore, Lounge, TV, and Flat), you can adjust your comfort whenever and however you want. This bed base has an advanced vibration massage system with four types, three intensities, and three time settings. Vibrational massage focuses on specific areas of the body and offers higher intensity than a traditional hand massage. Built-in Bluetooth® makes it easier to customize your sleep preferences with the MALOUF® Base app (Android and iOS), and the dual charging ports allow you to charge your device throughout the night. This base also includes a backup battery to power your base in the event of a power outage. Finally, the sleek, lined-inspired upholstered frame in Stone looks great on its own or fits into most existing bed frames. Since it s true zero clearance, it can sit directly on foundations, platform bases, slat beds, or the ground.
