A king mattress has more room for the royal family

Do your little ones find themselves in your bed at some point most nights or mornings? No matter how cute and cuddly they may be, sometimes there is simply not enough space for the whole family! And if pets tend to join the snuggle and snooze party as well, even a queen size mattress can struggle to keep everyone comfy and contained.

King mattresses help make things more comfortable for everyone. Whether you’re calming a child back to sleep after a bad dream, or watching cartoons together as a family on the weekend, king size mattresses give you the space you need.

A king size mattress gives couples room to move

At 80” long x 76” wide, a King mattress is the largest of the most common mattress sizes, surpassed only by its California cousin. This makes king size mattresses most often a choice of couples who want room to sprawl, toss, turn and take midnight bathroom breaks without disturbing their partner.
