Frequently asked questions

What are the benefits of an adjustable bed frame?

Adjustable massage bed frames are designed with features to help elevate your quality of sleep. The Anti-Snore sleeping 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 get restful sleep just the way you like it.

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.

What is the massage technology used in the Adjustable Base Max?

The Casper Rise Max adjustable bed frame incorporates massage technology for 3 levels of comfort. This massage option is designed to help you unwind and lull you to sleep, making it a fantastic adjustable massage bed frame.

What makes the Adjustable Base Max an exceptional adjustable bed frame?

The Adjustable Base Max is a unique adjustable bed frame that offers a full suite of customizable features for a personalized sleep setup. It includes the Zero Gravity position that helps relax your body for balanced comfort and an Anti-Snore feature that raises your head and chest to reduce pressure on your airway. This adjustable bed base also comes with wall-aligning technology that keeps everything within reach, making it one of the best adjustable beds in the market.

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.

What does "wall-aligning technology" mean?

The Adjustable Base Max features an innovative design that enables the head section to move independently when inclined — so no matter what angle you choose, this section is always the same distance from the wall and you're always able to easily access your nightstand.
