How to Buy a King Size Mattress for Your Bedroom Space

For bed buyers interested in sleeping on the maximum surface area possible, a king size mattress is usually the best choice. Nearly a foot and a half wider than the next largest mattress size, king mattresses prove especially ideal for couples preferring to have ample personal space while sharing a bed. The size of a king mattress, in fact, is roughly equivalent to the sleeping space created by pushing a pair of twin extra long mattresses together.

Good Option for Families
Ideal for those seeking the most undisturbed sleep. In addition to giving individuals the most room to sleep, king size mattresses often make perfect options for families with children or pets that like to spend quality time with the parents in bed. The ability, or lack thereof, to move and fit the mattress in the allotted space in the house remains the major issue associated with king mattress sizes.

King size mattress measurements run 76" wide by 80" long, with California king options spanning 72" by 84".
