Our take on the Serta Motion Perfect IV Adjustable Base (Split King)

The Serta Motion Perfect IV is a split king adjustable base: two independent halves that raise and lower separately, so each sleeper sets their own head and foot position. It carries an 850 lb capacity, a Wall Hugger design that keeps you near your nightstand as the head rises, Quiet Touch massage, preset positions, USB ports and a backlit remote with magnetic storage. The best new price is $1,399 at DealBeds.com as of November 4, 2026, with three stores listing it new. It assembles without tools and can sit on tapered legs or flat on the floor in zero-clearance mode.

Questions and answers

Is the split king worth it over a standard king base?
Yes if you and your partner want different positions. Each half moves on its own, so one can raise the head while the other stays flat. A standard king base moves as one piece.
What mattress do I need for a split king?
Two Twin XL mattresses, each about 38 by 80 inches. A single king mattress will not work because the halves move separately.
Does it work with a headboard?
Yes. Headboard brackets are included, and the Wall Hugger design keeps the mattress close to the headboard as the head rises.
Can I use it without legs?
Yes. The zero-clearance design lets it sit directly on a platform or the floor. Interchangeable legs set the frame height, with about 6 inches of floor-to-frame clearance.
What happens in a power outage?
A battery backup lets you return the base to a flat position. Keep batteries installed for this to work.
When is it cheapest?
Adjustable bases usually drop during holiday sales and mattress-event periods. The best new price was $1,399 at DealBeds.com as of November 4, 2026; check the price history before buying.
Where is the Serta Motion Perfect IV Adjustable Base (Split King) cheapest?
At DealBeds.com, for $1,399.00, 33% under what the other stores charge, as of our latest check.
