Natural 11 Inch California King Mattress

The Nolah Natural is a versatile 6/10 on the mattress firmness scale, offering balanced support, cushioning, and pressure relief. It's an ideal fit for side sleepers, back sleepers, and some stomach sleepers depending on their weight. For more information, see our Mattress Recommendations and Weight Tolerance page.

This natural mattress also uses hypoallergenic materials like organic latex, cotton, and wool, making it a good match for sleepers with allergies or asthma.

Yes. The Nolah Natural pairs well with any adjustable base, including our advanced Smart Adjustable Base.

This Nolah mattress purchase includes our 120-night at-home sleep trial! If, against all expectations, you don't love your mattress, you can return it for a full refund. Our logistics partner will pick up the mattress; you're only responsible for a $99 flat fee to cover labor and one-way transportation.

The trial begins the day your mattress arrives. Sleep on your Nolah mattress for at least 30 nights before making a decision—this gives you enough time to adjust to your new bed and fully experience its comfort and support benefits.

If you wish to return your mattress, please use the email form on our Contact page or email us at support@nolahmattress.com. You must initiate the return process after the 30-night break-in period but before the 120-night trial expires.

Return Process

1. Submit Request: Please use the email form on our Contact page or email us at support@nolahmattress.com to request a return. We cannot process returns over the phone or live chat, only through email. Once your request is received, a member of our customer support team will reach out to walk you through the rest of the process.

2. Schedule Pick-Up: We'll set up the scheduled mattress pick-up with one of our third-party logistics partners. The $99 flat fee (deducted from your refund) covers the pick-up and transportation. When possible, we arrange for the mattress to be donated to a local charity or mattress recycling program, depending on your state's laws.

3. Day of Pick-Up: Our support team member will provide instructions on what to do on the scheduled pick-up day. Typically, you leave the mattress unboxed for pick-up, and the driver does the rest. Then, email us a scan or digital photo of the pick-up receipt.

4. Refund: Once we receive a copy of the pick-up receipt, we'll process your refund in full (minus the $99 flat fee). You will receive a Refund Notification via email.

NOTE: Opting out of the 120-night sleep trial for additional savings disqualifies your mattress purchase for returns and exchanges.

Once you place your mattress order, we ship it out quickly from our factory in Arizona. You'll see an estimated timeline for when your mattress will leave the facility below the "Add to Cart" button on this page.

Once it ships, you'll receive a Shipping Notification with your FedEx tracking number at the email addresses used to place the order.

We partner with Load Up, a local third-party logistics partner, to offer white glove mattress removal and setup. You can choose from three service options: mattress removal only, mattress setup only, or our removal and setup package. For $225, the package also includes complete setup of a new Nolah foundation or adjustable base. Base or foundation setup is not available with mattress removal or setup only.

You can order white glove service right here on our website, in the "Optional" section on this page. Click "Add Mattress Removal & Setup" and choose one of the three options in the pop-up menu.

Once you have purchased an option, you will receive an email from Load Up to schedule the service. We recommend waiting to schedule until FedEx has delivered all your items. You can choose a 4-hour block of time on your preferred date.

A split king bed consists of two twin XL mattresses placed side by side on a king-sized base. Together, the two twin XL mattresses (38 by 80 inches) measure the same size as a standard king mattress (76 by 80 inches).

When you order a split king, you don't have to choose the same model or firmness level for the two twin XL mattresses. It's the perfect setup for couples with different body types, sleep positions, and comfort preferences.

Also, if you have a split king adjustable base, pairing it with two twin XL mattresses lets you adjust each side of the bed independently.

Ordering a split king bed from Nolah? If you select this option, the two twin XL mattresses will arrive in separate boxes and shipments with unique tracking numbers.

No. Nolah is committed to our customers' comfort and safety; all our mattresses are fiberglass-free.
