These queen and king adjustable bases are priced below market value. The Revolution 100+ adjustable base is a single motor bed which lifts the head of your mattress. It can also be used as a standalone power foundation with legs. The Soft Form technology harmonizes the mattress and the power foundation with your body and the platforms allow the mattress to curve naturally instead of making hard angle bends which greatly reduces the stress on the mattress and the resulting gaps between the two. In addition, it has a USB charging port.
