What is a California King Mattress?

What’s the difference between a regular king-sized mattress and a California king? The main difference is that a California King tends to be a few inches longer, but also a few inches narrower. It’s also worth noting that, while pretty much all mattresses come in a king size, not all of them are available in Cal King.

Shopping Considerations

There are a number of factors to consider as you seek the Cal King that’s best suited to your sleep preferences.

Type of Mattress

Memory foam: Memory foam mattresses tend to be supportive and great for both motion isolation and pressure relief. The downside is that many memory foam mattresses run hot.

Innerspring: Innerspring mattresses are made with individual coils, which adjust to the movements of the body and offer targeted lumbar support. These mattresses tend to be cooler, though older ones can also be noisy.

Latex: Latex is cool to the touch and helps promote air circulation. It’s also bouncy and responsive. The downside here is that it tends to be on the more expensive side.

Hybrid: Hybrid mattresses are made by combining the best features of memory foam, latex, and innerspring.

Performance Factors

Set-up: Consider how long it will take you to get your California King size mattress set up and ready for use, and whether you’ll have any off-gassing to contend with.

Pressure relief: Seek a mattress that evenly distributes body weight and relieves pressure on your joints.

Spine alignment: How well does your California King bed support a natural, healthy posture? It all depends on the materials used to support the body’s pressure points.

Durability: Look for a bed in a box mattress that’s built to last, specifically one that’s constructed with high-quality materials and supported by a generous warranty.

Motion transfer: Motion transfer is the measure of how well a mattress suppresses movements and keeps one partner from disrupting the other.

Temperature regulation: Look for a mattress that’s made to mediate body heat, especially if you tend to sleep hot in the nighttime.

Responsiveness: Responsiveness is the measure by which a mattress adjusts to the movements of your body.

Edge support: Look for a mattress that won’t sag around the edges.

Price

Price is determined by the mattress type as well as the mattress size; as such, you’ll pay more for a Cal King size bed than you would for, say, a Twin or a Twin XL, though there can still be a lot of pricing variability between Cal King products.

Shipping and Delivery

Another consideration: How long will it take for your mattress to arrive? Also think about whether there are shipping or return costs, and whether white glove service setup is available.

FAQ About Cal King Mattresses

How can I tell if my mattress is eco-friendly?

One way to tell is to look for an indication that it’s CertiPur-US certified, which denotes that it has passed some basic emissions tests.

How do sleep trials work?

You’ll be granted a certain number of days to try out the mattress and ensure it’s right for you. You may return the mattress within that window for a full refund. (A few mattress bands may subtract a small return fee, usually no more than $100.)

Is financing available for my Cal King?

Most mattress companies will offer financing options through a service like Klarna or Affirm; look for these options when you check out from the mattress company website.
