The Complete Guide to Buying a California King Size Mattress

Choosing a new mattress is a major investment in your sleep quality, and if you’re looking for extra length and luxurious space, a California King may be the perfect fit. This oversized mattress style is ideal for tall sleepers, couples who love to stretch out, or anyone upgrading their bedroom to a more spacious, premium setup. Use this guide to understand what to look for, how to compare options, and how to make a confidently informed purchase.

What Is a California King Mattress?

A California King mattress typically measures 72" wide by 84" long. While it’s slightly narrower than a standard King (76" x 80"), it offers four extra inches of length—making it one of the longest mattress sizes available. This added length makes it especially appealing for people over six feet tall or for those who simply prefer a larger sleep surface.

Measure Your Space First

Before you shop, take time to measure your bedroom. A California King generally requires a room that is at least 12' x 12' to ensure enough space for movement and furniture. Don’t forget to consider the path from your home’s entrance to the bedroom; tight staircases or narrow hallways can make delivery challenging. Planning ahead helps avoid last-minute surprises.

Know Your Mattress Types

When buying a California King, you'll be able to choose from several mattress constructions. Understanding these types will help you narrow down your options:

• Memory Foam: Known for pressure relief and contouring support. Stays supportive the "least" amount of time of any mattress type so be prepared to replace more often.

• Hybrid: Combines innerspring pocket coils with foam layers for balanced support and comfort. Ideal for couples due to good motion isolation. Two sided flppable models are best for long term comfort and durability.

• Latex: The best at naturally cooling, durable, and responsive.

Check Firmness Levels

Mattress firmness plays a big role in comfort.

• Soft: Best only for light-weight sleepers and side sleepers.

• Medium-Cushion Firm: Versatile choice suitable for most sleep styles.

• Firm: Supportive for back and stomach sleepers or heavier individuals.

If you’re unsure, medium-firm is usually a safe baseline that suits a wide range of sleepers.

.Evaluate Durability and Warranty

Because of its size, a California King is a long-term investment. Look for mattresses with durable materials, strong edge support, and warranties of at least 10 years.

Don’t Forget the Foundation

A California King requires a supportive base, whether a platform bed, adjustable frame, or box foundation. Make sure the foundation is rated for your mattress type to maintain comfort and prevent sagging.
