Shop by Size - King

Want to sleep better than the Queen of England? With 26% more sleep surface than a Queen, King size mattresses are perfect for single adult sleepers and couples who want a lot of surface area to stretch out and relax!

The standard measurement for King mattresses is 76" x 80" (6.33' x 6.7'). The king-size bed is the widest standard size you can get. A split king or dual king mattress comes in two pieces rather than one, with each piece about the size of an extra long twin mattress. This is a perfect option for couples looking for an adjustable base set with individual control!

Bed Smart Tip

Don't let your bed fall flat - upgrade your sleep space with a power base to maximize the comfort and health benefits of your mattress!
