Split King Adjustable Base

Did you know?

While a standard king mattress works with a split king base, you can create a customizable sleep system with a split king mattress and split base. Here’s what to know when making the upgrade.

It’s like having two beds in one.

Two Twin XL mattresses create a Split King set. For easy maneuverability, your adjustable base will arrive in two parts.

Welcome to sleep harmony.

Do you and your partner have different sleep needs? Hot sleeper? Need more support? With a Split King set, you can each choose the best mattress for you. Make sure the profile height of each is same, or it may be difficult to snuggle.

Read, lounge, sleep, and more without disruption.

Using two Twin XLs allows each sleep partner to control their side of the bed independently, giving you unbeatable personalized comfort.

Frequently asked questions

What are the benefits of an adjustable zero gravity bed frame?

Adjustable bed frames are designed with features to help elevate your quality of sleep. The Anti-Snore position elevates your head and chest to help reduce pressure on your airway — a common cause for snoring and sleep apnea. Other positions like Zero Gravity promote muscle recuperation to relieve stress on your body for balanced comfort. Adjustable bed frames even come in a Split King option, so you and your partner can sleep just the way you like it – making our zero gravity bed frame the best adjustable bed you can get.

How will my adjustable bed frame be delivered?

We offer shipping via UPS for the Adjustable Base, Pro Adjustable Base, and Max Adjustable Base. Depending on which size you order, your bed frame will arrive in either one or two boxes. Additionally, we offer In-Home Delivery and Setup across the 48 contiguous states in the US and for an additional cost.

Is the adjustable base compatible with other mattresses?

The adjustable base is compatible with most foam and hybrid mattresses. We don’t recommend using the adjustable base with a traditional spring mattress.

Can I use an adjustable base with my existing bed frame?

The Adjustable Base, Adjustable Base Pro, and Adjustable Base Max are compatible with Casper Repose and Casper Haven bed frames. Customers should check their bed frame's dimensions and weight capacities for use with a non-Casper bed frame.

I need a split king base. Do you offer that?

We do! For those who aren’t familiar, a split king basically means the frame comes in two parts. With an adjustable base, the two parts are able to work separately or sync together — so you can use the base with two twin XL mattresses or a single king mattress.

Our Cal king adjustable base is also split, but can only be used with our Cal king sized mattress.
