What does the SmartFlex SF300 adjustable base do?

The SF300 independently articulates the head and foot of your mattress, so you can find comfortable angles for sleeping, reading, or watching TV. According to The Mattress Factory product listing, it comes with preset zero-gravity and anti-snore positions, Bluetooth compatibility, and USB charging ports, all run from a 9-button wireless remote with a built-in flashlight and a programmable memory button to save your favorite position.

How do the zero-gravity and anti-snore positions help?

Both are presets that change your posture for more comfortable rest. The zero-gravity position elevates the head and legs to distribute weight evenly and relieve pressure points, while the one-touch anti-snore button raises the upper body to adjust your sleeping angle and help reduce snoring. Tap once and the base moves you into position—no manual fiddling required.
