King size bed in bedroom


Maybe you’re looking for a bigger bed because you and your partner want more sleeping space. Or perhaps you have kids who end up snuggling in bed next to you on those sleepy Sunday mornings. Or maybe your pet has mattress privileges and your current bed just isn’t going to cut it anymore. Whatever the reason, getting a king bed is the best route for gaining extra sleeping space. The 72-inch to 76-inch width, depending on which you choose, gives each person a section of bed that is roughly the same size as a twin bed.

Available Bedroom Space

Grab that measuring tape and take the time to get the dimensions of your room. You’ll want to leave enough space to comfortably walk around the bed, so consider making an outline of the bed with painter’s tape so you can visualize the actual size. Don’t forget to measure out the hallways, doors, and stairs to make sure you can move the mattress of your choice into your home.

Typically there isn’t much of a price difference between a California king and a king mattress. However, when you are upgrading your mattress size, be mindful that you will need to purchase new sheets, along with a comforter, bed frame, and headboard.

Body Type

If you are going to invest in a new bed, make sure you buy a mattress that fits your body type. If you or your partner is taller than 6 feet, you may prefer the extra 4 inches of length that come with the California king. But if you like to spread out when you sleep, you may prefer that wide open space found in a king-size bed. Either way, it’s all about getting the good night’s rest you deserve.
