What Size is a King Size Mattress?


A standard king size mattress measures 5 ft. in width, perfect for couples who prefer a little extra sleeping space. Our king size mattresses provide plenty of support, with choices including those with latex foam layers or high-density foam for extra comfort.

If you want a comfortable night’s sleep, then the more space you have, the better. One of the main reasons people do not sleep well at night is because they do not have adequate space to move about in. For many individuals, a double bed is sufficient, but for those who are taller or who need the extra room, a king size bed is a better option.

When it comes to buying king size beds, there are plenty to choose from at BedSOS. We have fabulous bed frames made from fabric, metal, wood or leather, and some have built-in storage space or room to house a flat screen TV. One thing they all have in common is the need for a king size mattress.

While the bed frame can be contemporary or modern depending on preferences, the mattress you choose will depend on your choice in terms of traditional sprung mattresses or foam mattresses. Here at BedSOS we have plenty for you to choose from.
