Frequently Asked Questions
About California King Mattresses at Sam's Club
How to Choose the Right California King Mattress
The California king is built for taller sleepers who don’t want their feet hanging over the edge. Here is how to find the right one.
A California king mattress measures 72 by 84 inches, making it the longest standard mattress size available. It’s four inches narrower than a standard king size mattress, but four inches longer, which makes it the right mattress size for taller sleepers and master bedrooms with a longer, narrower floor plan. Sam's Club carries California king mattresses in memory foam, hybrid and innerspring options across a full range of firmness levels.
Who Is a California King Mattress Best For
California king mattresses are ideal for sleepers over about 6 feet tall, couples where one or both partners are tall, and master bedrooms that are longer than they are wide. If your room is more square or total surface area is more important than length, a standard king mattress gives you more overall width. For most tall sleepers, the Cal king's extra four inches of length is worth it for a noticeably better sleeping experience.
Picking the Right Type and Firmness
California king mattresses are available in the same types and firmness as other mattresses. Side sleepers benefit from a soft to medium surface with good contouring and pressure relief. Back sleepers and stomach sleepers do better on a medium-firm or firm mattress for proper spinal alignment and lower back support. A hybrid mattress is a breathable and durable choice for active sleepers or hot sleepers who need good airflow.
