The M555 Adjustable Base takes relaxation to the next level. With 5-presets 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 4-types, 3-intensities, and 3-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 battery to power your base in the event of a power outage.
