An adjustable base stops feeling like a gadget the first night you read in bed without stacking four pillows behind you. The XSF250 raises head, lumbar and foot independently, which is the difference between propped up and actually supported.

Dual multi-level massage, anti-snore, TV and zero-gravity presets, USB-A and USB-C charging, a motion-sensing night light and a solar-charging wireless remote round it out, with a phone app if you would rather not hunt for the remote at all. A child safety lock and anti-entrapment sensors are built in. Patented one-piece folding means it arrives ready to set up, and adjustable steel legs plus a universal headboard bracket let it drop into an existing platform bed or frame without redesigning the bedroom.
