King Mattress
At 80 inches in length and 76 inches in width, the king size mattress is usually the ideal option for couples who want ample sleeping space. This mattress is essentially the same size as putting two twin XL mattresses together. If you have cats, dogs, or kids who will be sharing your bed with you, this might be your best choice. The box springs for king size beds are generally split due to the sheer size of the mattress. This makes it easier to move the rigid foundation around tight corners and stairs. Of the standard mattress sizes, the king size is the most spacious.
