Split California King Size Mattresses

Picking the right mattress to help ease back pain starts with assessing your typical sleep position, then choosing a mattress firmness that best supports you in that position.

Saatva mattresses are the only ones with patented Lumbar Zone® Technology. That means every Saatva mattress is designed with dedicated lumbar support at the center third of the mattress where you need it most. Benefits of this lumbar zone support include better spinal alignment, circulation, and pressure relief.

No. Bed in a box (BIAB) mattresses are compressed, shrink-wrapped, folded, then rolled into a cardboard box for shipping. While this allows BIAB companies to save on freight costs, it takes a severe toll on the integrity of the foam mattress by breaking down the cell structure of the foams. It can also result in uneven firmness and sinking support in some areas, reducing the overall lifespan of the mattress.

We believe your bed deserves better than being stuffed in a box. That’s why all Saatva mattresses come with FREE white glove delivery and in-home set up. We even take away your old mattress for free!

You can use your existing box spring or foundation if:

• You purchased your box spring or foundation within the last seven years

• Your existing box spring or foundation is in good condition and provides sturdy center support

NOTE: Saatva HD requires pairing with the HD Foundation for adequate support.

Saatva mattresses also work with platform beds, without the need for a foundation or box spring. Please make sure your existing platform bed has the following:

• A solid, durable surface. If your platform has a slatted support system, make sure the slats are spaced less than 4" apart. If they're not, you can add a 1/2" thick piece of plywood or a bunkie board over the slats for optimal support. This extra layer of support is needed because Saatva mattresses are heavier due to their premium quality materials

• A proper center support. This means you must have a center leg in the middle of your platform bed frame

NOTE: When used with our dual-sided Zenhaven mattress, you must add a solid surface over platform slats such as plywood, masonite board, or bunkie board.

If you have any questions, you can reach one of our sleep guides 24/7 at 1-877-672-2882.

Saatva mattresses are compatible with any bed frame, including our Saatva bed frames.

Our dual-sided Zenhaven latex mattresses cannot be placed directly on a platform bed frame with slats. You must cover the slats with a solid material, such as plywood or a bunkie board.

Non-platform (standard) bed frames require a foundation and can be paired with any mattress. Note that we strongly suggest pairing the Saatva HD with the HD foundation, which is specifically designed to give it optimal support.

Yes! Our Saatva Viewing Rooms are inviting, pressure-free spaces to experience Saatva comfort in real life.

White glove delivery is the Saatva service standard and comes free with every mattress, bedroom furniture, and rug order. While our teams don't actually wear white gloves, we do all the work for you.

We hand-deliver your mattress and set it up in the room of your choice. We also take away your old mattress and foundation* if you select the "free mattress & foundation removal" at checkout—all at no extra charge!

Typically, mattress orders are delivered from our factories within a 9-21 day time frame, depending on your zip code.

Our bedroom furniture is also hand-delivered and assembled (if applicable) and bedroom rugs are delivered and set up in the room of your choice (rug area must be cleared of furniture by customer prior to delivery). You get all this for free as part of our premium white glove delivery service.

*Note that our delivery teams won't take away the following items:

• Waterbed bases

• Standard metal bed frames

• Sleep Number bases

• Stained and/or damaged mattresses & foundations/box springs

We never resell returned mattresses. Instead, we donate them to veterans' shelters or offer them at cost to employees and associates across our network of more than 150 delivery partners.

Every Saatva mattress is made to order, which means they don't sit in storage.

Occasionally, we can shorten the delivery time when we have a change or cancellation from another order of the exact same product. This allows us to redirect that freshly made and sealed mattress to you. We’d love to help in any way if you need your mattress faster. Our friendly sleep guides are here for you 24/7 at 1-877-672-2882.

We offer a year-round $225 discount off orders of $1,000 or more to active military, veterans, first responders, government employees, nurses, teachers, senior citizens & students.

No. It’s part of our pledge to be honest and transparent about what you’re buying. Saatva is committed to giving you honest guidance, even if it means directing you to another mattress brand that’s a better fit for you. In a regular mattress store environment, a commissioned employee makes more money when they sell you a particular brand, so you may get pressured into a choice that’s not right for you. That’s just not the Saatva way.

Mattresses crafted in the U.S.A. must meet strict health, safety, and environmental standards. The U.S. and the E.U. have the toughest regulations, but other countries may not offer the same protections.

Knowing where your mattress is crafted makes it easier to ensure that the manufacturer adheres to guidelines that protect workers from danger and exploitation, such as labor regulations and minimum-wage laws. Reputable mattress manufacturers (like our network of 14 domestic factories) also work to minimize environmental impact by incorporating low-carbon-footprint processes and recycled materials into their products.

This type of mattress uses memory foam as its main support layer. Memory foam, also known as viscoelastic foam, is a type of high-density polyurethane foam. Its distinguishing feature is that it softens in response to heat and pressure. That’s what gives memory foam mattresses their body-hugging, body-contouring feel.

A latex mattress consists (either partially or entirely) of layers made from natural latex foam from the sap of the rubber tree. A natural latex mattress can last up to 20 years, making it one of the longest-lasting mattress types on the market.

Technically, the term “hybrid mattress” can be used for any mattress that is made from more than one material. It’s most often associated with innerspring mattresses that contain a coil support system along with another material such as memory foam or latex.

The innerspring mattress gets its name from the metal support coil (also called springs) that form the core of the bed. This traditional mattress type is known for its classic springy, bouncy feel. A basic innerspring mattress will last you about 7-8 years. Saatva innersprings can last upwards of 10 years with normal use.

A pillow top refers to the extra layer of cushioning on the top surface of a mattress. These are most commonly found on innerspring or innerspring hybrid mattresses. Pillow top cushioning can be made from memory foam, latex, foam, fibers, gel, or other materials.

A conventional pillow top is sewn onto the top surface of the mattress. A Euro pillow top (also called a Euro top), by contrast, has the padding built in underneath the top cover and is flush with the mattress edges, so it doesn’t look like an extra layer sitting on top of the mattress. Our Saatva Classic, Saatva HD, and Solaire mattresses all feature a 3” Euro pillow top for added cushioning.

A Split King mattress has the exact same dimensions as a king mattress, but made up of two separate Twin XL mattresses. This is a great option for those who have narrow entryways and staircases.

Split King is also a great option for couples who want a king size mattress, but have different firmness preferences. Simply order two separate Twin XL mattresses in different comfort/firmness options. If ordering two different mattress styles, be mindful of the mattress heights for each mattress.

Lastly, Split King mattresses are great paired with a Split King adjustable base so that each sleeper can control the head and foot incline/decline on their side independently from their partner.

To order a Split King consisting of two different mattress types, add the two Twin XLs you want to your cart separately rather than selecting Split King size. If you need any assistance placing the order, give our sleep guides a call at 877-672-2882.
