What to look for in the best adjustable king bed

The best adjustable king bed can help you personalize your comfort, support your sleep position and make it easier to relax at bedtime.

1. Mattress Compatibility

Make sure the mattress is designed to flex with an adjustable base and matches the base dimensions. Some adjustable king beds use two Twin XL mattresses to create a split king, which allows each side to move independently.

2. Adjustable Positions

Look for a base with head and foot adjustments that suit the way you sleep, read or relax. Preset positions such as zero gravity, lounge or anti-snore can make adjustments simple.

3. Features And Controls

Consider helpful features such as a wireless remote, app controls, massage settings, USB ports and under-bed lighting. Choose the options that fit your routine without paying for features you may not use.

4. Size And Support

Check the base dimensions, weight capacity and clearance to make sure the bed fits your bedroom and supports your mattress, bedding and sleepers. If you are replacing an existing frame, confirm whether the adjustable base can work with it.
