The 5 Best Split King Adjustable Beds in 2026

The secret to getting a good night’s rest is finding the perfect sleeping position that keeps you comfortable AND supported. Maybe you’ve already figured out what works best for you.

Upgrading to a split king adjustable bed might be the solution you’ve been searching for. Not only does a king mattress give each of you the space you need to sleep comfortably, but a split king in particular enables you to customize the settings on each side separately.
