For those who are always seeking more legroom, our California King (also referred to as CA or Western King) mattresses provide the longest sleep surface we offer.

As an alternative, this size is offered in a split format.

King-size mattresses measure 76” W x 80” L. California king-size mattresses measure 72” W x 84” L. This means that California King mattresses give taller sleepers extra room to stretch out.

BASE OR FOUNDATION

The mattress does not come with a base or foundation, but you can purchase either one to support your mattress. Box springs cannot be used with our mattresses, and will void the warranty. You can also place the mattress into your bed frame, provided the bed is structurally sound, and has either a flat surface or slats that are at least 3" wide and no more than 4" apart.

PROTECTOR

While your mattress does come with a cover, it is not a waterproof protector for the mattress. We recommend purchasing a mattress protector that will keep your mattress safe from liquids, humidity, mites, and anything else that might harm the mattress material.

SHEETS

Any brand of sheets will work for our mattresses, but ours will be best. The corners of our fitted sheet will have patented straps to keep the sheet tightly and neatly in place, resulting in less wrinkles and less re-adjusting.

Simply put, for a full decade after you purchase your new Tempur-Pedic®, if the mattress has a defect covered under the warranty guidelines, we’ll replace or repair it. This includes all parts of the mattress. Note that there are certain circumstances that will automatically void the manufacturer’s warranty, including inappropriate foundation use and physical damage. You can read the full warranty details here.

Split CA King mattresses are comprised of 2 mattress halves that make up a whole; this allows you to further customize your comfort by having the option to select a different feel for each side of the bed, or pair with a split adjustable base.

If you purchase a split California King mattress, you will need split California King sheet set. The set will come with two fitted sheets, one flat sheet, and two pillowcases. You can find our sheets online here.
