Our take on the MotoSleep ISF350MSA Split King Adjustable Base

The MotoSleep ISF350MSA is a split king adjustable base sold as two Twin XL bases, so each side of the bed moves independently. Each base has head and foot articulation with anti-snore, zero-gravity and TV presets, plus memory positions, dual massage, an audio system and a motion-sensing multi-color night light. It adds app control and USB-A and USB-C charging ports, which puts it above basic wired-remote bases. It suits couples who want separate positions and adjustable steel legs for a platform setup. The split design means two motors and two remotes to manage, and it is a final-sale item with no returns.
