No. Both beds have different dimensions. A California king bed measures 85 inches long and 72 inches wide while a king measures 76 inches wide and 80 inches long. The length and width of both beds differ which makes it very unlikely for a California king bed frame to fit a king. When you try it, parts of the mattress would stick out and it would not properly fit. Trying to make a California king fit a king could damage the mattress and even make you underuse features of the bed.

Trying to use a California king sheet on a king size bed would not be appropriate because of the difference in width. Regardless of how much you might want to maneuver the bed sheet to fit, it just won’t because a king size bed is wider than a California king. Though some California king bed sheets could fit on a king size bed  it would look totally out of place because of the difference in dimensions.

It was called California king by a Los Angeles Merchant in the 1920s and 1930s after world war II. This merchant believed that Californians already had big enough beds and big enough houses for their lifestyles. So he built a bed that is seven feet long and six feet wide. 

Though, there is another story about a tall man in Concord, California who built the bed in 1982 to accommodate his height. Despite the different stories, they are well-known for their popularity in the mid century and their close association with celebrities lifestyle.


The mattress that you choose to invest your money on goes a long way in determining your health, productivity and entire life. We often overlook this aspect and just settle for any mattress that we think is right. But mattresses have caused chronic back pains, misalignment of spine and made some regulars at the doctors office. In order to prevent this occurrence we present you with mattresses that provide you with good sleep as well as they pay attention to your general health.

Also, harmful substances like mercury have been found in some mattresses and their health implications are so profound. Choose a mattress that has credible certification from recognised organisations that focus on eradicating such occurrences. The mattresses that we bring to you are not just great products but they have credibility.

Getting a mattress that would not last long is a stress that no one deserves to go through especially because of the weight of beds. The mattresses that you pick have to have a long lifespan so you do not just waste your money one bed having to buy another. Choose the bed with the feel that compliments your health issues or your preferences so as to save yourself from any stress.

Some people prefer soft beds while others would go for firm ones, however the best kind of beds are those that have medium feel. The only reason why people should use very firm beds is probably based on the doctor’s advice. Soft beds can also be great as long as they do not sink or put your body in the wrong position.

Buying a bed as wide or as long as the King and California King bed could end up being a waste if your bed choice is not suitable for all sleeping positions. Your bed has to be compatible for side sleepers, stomach sleepers and back sleepers. Our products provide you with this feature as it accommodates any style you, your partner or your child prefer to sleep.

By reading through this article, you would find the very bed that fits into your master bedroom be it narrow or wide. It would also help you determine your choice based on your budget and the comfortability that you truly desire.
