Measurements & Dimensions

At four inches longer than a King or Queen mattress, the Leesa California King is an excellent choice for taller sleepers who need that little extra room for comfort. Easy to set up on a smooth firm surface, your Leesa California King, like all Leesa Mattresses, comes directly to your front door, compressed in a manageable 18” X 18” x 45” in box, so there are no costly delivery or setup fees.

Choosing The Right Bed Or Foundation

Choosing the right surface that supports a mattress can affect the way it feels. The Leesa mattress is designed to deliver its signature feel sitting on a firm, flat, and sturdy surface. Traditional box springs or flexible slats can make any mattress feel too soft. Solid or slatted bases are recommended. Slats should be solid and with no give. Avoid curved slats because they do not offer sufficient support. For the optimum feel, slats should be no more than 3 inches apart.

What other Leesa customers are saying

Your top 5 questions, answered

1. How long will it take to receive my Leesa mattress?

Once an order is placed, we need 2-3 business days to build and compress your Leesa before boxing and shipping directly to you. UPS transit times vary between 1-3 business days depending on location. We will send you an email with your tracking details as soon as your order ships.

2. Is the Leesa easy to set up?

Setup is easy. Your Leesa mattress comes compressed, rolled and boxed.

Move the box or bedroll into the room where you intend to set up. It's much easier to maneuver at this point.

Position the bedroll on your stable base and begin to tear away the plastic.

The mattress will immediately start to take shape and before you know it, you'll find yourself gazing down at your brand new, ready-for-sleep Leesa mattress.

For detailed step-by-step instructions, read the Set up Your Leesa How-to FAQ or you can refer to the step-by-step setup guide that arrives with your Leesa.

3. Do I need a box spring or foundation?

The Leesa mattress is designed to deliver better sleep. To be most effective, your Leesa should be set up on a stable base that is substantial enough to support both mattress and sleepers. Great options for setting up your Leesa:

  • traditional metal frame and foundation
  • platform bed or slatted bed
  • adjustable base
  • Murphy bed
  • flat on the floor

Box foundations are often made of plywood and can splinter, crack, and deteriorate with age. Double check to be sure your box foundation is in good repair before setting up your Leesa. Box springs are made with springs and can change the way the mattress feels for some sleepers. If you have a box spring try adding a 1" - 3" board in between the box spring and your mattress as a suitable and wallet-friendly option.

If you are unsure about your setup, give us a call or send us a quick message. We’re happy to help.

4. How does your return policy work?

First, try your Leesa for at least 30 nights. This allows your body ample time to adjust to the feel of a new mattress.

We’re confident you’ll love your Leesa but if you don’t, you have up to 100 nights to let us know. There are zero return fees and you do not have to worry about fitting your Leesa back in the box. We’ll arrange to have your mattress picked up from your home with no additional effort or cost on your part. We do our best to locate a charity in your community otherwise we coordinate your pick up with our recycle partner. Then we refund your purchase in full.

5. Do I need a mattress protector or mattress pad for my Leesa?

Mattress protectors are a great way to shield your mattress from life's little accidents. Look for a highly-recommended brand that offers a waterproof, hypoallergenic protector made of breathable fabric.
