- 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.
