King/california King Size Mattress

There are many reasons for choosing a King over a queen size mattress. The most common reason being a family who likes to share their bed with children and pets, and who like enough space between so as not to get overheated while sleeping.

The ample space also minimizes interruptions while you sleep. Most individuals who fall into the category of Big and Tall will be able to find ample comfort on a mattress that is King or California King size.

Mattress depth is important here, as heavier individuals will sink further into the mattress. Look for mattresses with a depth of at least 12 inches. The mattress should be firm enough to be supportive, but not too firm that it causes pressure points.

High-density mattresses are a great option for people of a larger size, as they will provide enough support for those who sink far into the mattresses.

A king size mattress affords you an extra 16 inches of width from a queen , making a total width of 76 inches. A California King gives away 4 inches in width from a king and but gains 4 inches in length, making it a better choice for taller individuals.

The King Of Mattresses

If you or your partner take up a lot of sleeping surface or are easily disturbed, a king mattress may give you both the room you need. It can also come in handy if you have kids or pets that like to jump into bed with you.

The size can also be a drawback, though. It requires a more substantial and supportive foundation, larger and more expensive bedding and sheets, and you’ll even want king-size pillows, as standard ones appear dwarfed.

The cost of a king mattress typically runs 20-30% higher than an equivalent queen-size bed .

A king size mattress is almost exactly the same size as two twin XL beds, so if you like the size of a king, but you and your partner have different preferences, you could opt for two twin XL beds side by side, covered with king-size bedding.
