With the best brands in your favorite sizes, Mattress Firm has you covered. Our selection of Simmons Beautyrest California King mattresses is unmatched. The California king bed measures 72" by 84", longer and slightly slimmer than a traditional king bed, ideal for taller sleepers, or those who like a big bed while still sleeping close to a partner. Whether you're looking for a plush Beautyrest California king mattress, a firm Beautyrest California king, or something in between, you'll find it right here at Mattress Firm.
