A California King mattress offers an ideal sleep solution for couples, tall sleepers and anyone who wants more room to stretch out at night. Measuring approximately 72 inches wide by 84 inches long, a California King provides generous length without taking up as much width as a standard king mattress, making it a practical choice for spacious bedrooms with a narrower layout. Choose from popular California King mattress types, including memory foam, hybrid, innerspring and latex, to find the comfort, support and temperature regulation that match your sleep style. Couples may benefit from a California King mattress with motion isolation, while combination sleepers can look for responsive comfort that makes changing positions easier. Mattress Firm carries California King mattresses in a variety of comfort levels, so you can find a sleep surface that helps support restful nights and better days Complete your California King sleep setup with a sturdy California King bed frame, adjustable base or platform bed designed for the mattress size. The right foundation can provide reliable support while creating a polished centerpiece for your bedroom. California King sheets, mattress protectors, pillows and comforters add comfort and help keep your mattress clean, fresh and protected over time. For a more personalized setup, consider an adjustable base with head and foot elevation, cooling bedding for hot sleepers or supportive pillows that promote comfortable alignment. Mattress Firm Sleep Experts® can help you compare California King mattresses and accessories, understand the differences between materials and build a complete sleep solution that fits your space, preferences and budget.
