What Is a Split King Adjustable Bed?
A split king is the most popular adjustable bed configuration for couples. It uses two Twin XL adjustable bases placed side by side to form a 76" x 80" king-size sleeping surface. Each person gets their own remote and can adjust their side independently. This setup requires two separate Twin XL mattresses rather than a single king mattress.
Which Size Fits Your Room?
Twin and Twin XL bases fit rooms as small as 7' x 10' to 8' x 10'. Full bases need at least 10' x 10'. Queen bases work best in rooms of 12' x 12' or larger. King and Cal King bases require 12' x 12' minimum, with 14' x 16' recommended for a spacious layout with nightstands and a dresser.
Pairing Your Adjustable Base with the Right Mattress
Regardless of size, your mattress needs to be flexible enough to bend with the motorized base. Memory foam, hybrid, and latex mattresses are the best choices. Browse our mattresses by size collection to find compatible options in every dimension.
Head-Only vs. Head-and-Foot Models
Every size in our collection is available in both head-only and head-and-foot configurations. If you are unsure which adjustment type suits your needs, compare both options in our adjustable beds by type collection before selecting a size.
