Frequently Asked Questions
Will a split California King base fit in my current bedroom?
A split California King base usually measures 72 inches wide by 84 inches long. Since it arrives as two separate units, it is easier to maneuver through tight hallways and stairwells than a single, massive piece. Measure your room carefully to ensure you have enough clearance for the base to fully recline.
Do I need special sheets for a split bed?
Yes, you need split California King sheets. Because each side moves independently, a standard fitted sheet would pull off the mattress the moment you raise the head of the bed. You will need two separate fitted sheets and one flat sheet to complete the set.
Can I use my old mattress with an adjustable base?
You can reuse your mattress only if it is a compatible memory foam or latex model. Traditional spring mattresses often contain rigid border wires that prevent the bed from bending. Forcing a spring mattress into a bent position will ruin the internal structure of the bed.
How do the two sides stay together?
Most manufacturers include retaining bars or connecting clips that keep the two bases from drifting apart. These ensure the bed feels like one cohesive unit while you sleep. They are simple to install and keep your sleep surface secure throughout the night.
Is the remote control wireless or wired?
Most modern bases come with wireless remotes for convenience. These units often feature backlighting so you can find the buttons in the dark. Some premium models also offer a smartphone app to control your position if you prefer not to keep a physical remote on your nightstand.
