Know before you buy
The split design means you receive two separate base pieces that function independently. This allows you and your partner to adjust your head and foot positions, lumbar support, and massage settings individually without affecting the other side.
With a slim 3.75-inch profile, this base is designed to fit inside most standard bed frames. However, ensure your frame has a flat, solid surface or slats that can support the weight of the base and your mattress.
The Zero Gravity preset elevates your head and feet to a position that mimics weightlessness. This alignment helps distribute your body weight evenly, which can significantly reduce pressure on your lower back and improve circulation.
Yes, you must use an adjustable-friendly mattress. Most modern memory foam or hybrid mattresses are designed to flex with the base, but you should verify compatibility with your specific mattress manufacturer to ensure it won't be damaged by the movement.
The lumbar support feature allows you to add extra firmness and contouring to the lower back area of the base. It provides targeted relief by pushing upward to maintain the natural curve of your spine while you are in a seated or reclined position.
The massage settings are designed to be subtle and soothing rather than intense. While there is a faint mechanical hum during operation, it is generally quiet enough to use for relaxation or recovery without being disruptive.
