Factors to Consider While Buying a King or a Full Mattress

If you’re looking for a luxurious touch to your bedroom, the California king mattress will be perfect for you and your family. But you must question and undermine factors like the room size, costing, requirements, and the sleeping requirements – how does each element when choosing between these two sizes matter.

  • Room Dimensions

Room size stands still amongst one of the most critical aspects of deciding between mattresses. In such scenarios, always measure your room before finalizing a bed. If you’re two people accomodating on one bed (refer to the table above), then California King is worth an investment. The required room size to fit a Cal King mattress is 13 x 12 ft minimum.

However, a full mattress will make the most sense if you have a comparatively smaller room. The required room size to fit a full bed is 10 x 11 ft. Recent graduates and young adults are ideal candidates for a full size mattress. 

  • Cost

Investing in a California King bed or a full size mattress isn’t an expensive affair. Both mattresses come at a reasonable price which will not seep a hole in your pocket. A California King mattress ranges from $800 and may go up to $1000. At the same time, a Full Size mattress ranges from $1100 and will go up to $1400. Notably, the prices may vary from brand to brand and as per your preference for additional bedding accessories.

  • Height

When it comes to California King and Full Size mattresses, one thing you definitely cannot compromise upon is the length. For taller people who don’t want their legs to hang off the bed, which may lead to discomfort, cold, and unrest of sorts… California King single-handedly wins the show. With a massive difference of 18 inches, Cal King makes an ideal bed for tall people– 6”’ ft and above. In contrast, full size may only suit someone with a moderate height of 5″ 5′ ft and below.

  • Sleeping Partner

Another aspect to consider while deciding between a Cal King and Full mattress is the sleeping style of you and your partner. Ideally, if you prefer sleeping tight while snuggling and being cozy, a Full mattress may help! But it’s best suited to single sleepers who like to spread out nicely and sleep like a king– all alone.

Whereas a California King is apt for couples who like their own space on the bed, prefer some extra room, and want to sleep comfortably. The extra length and width give you the freedom to rule the bed on your distinctive sides handsomely.
