The California king size mattress and standard king size mattress have different dimensions. It’s important to know the differences, especially when shopping for bedding or a bed frame.  Let’s take a look at the difference between king size and California king size mattress dimensions:

King size mattress: 76 X 80 inches

California king size mattress: 72 X 84 inches

The California king size mattress size is 4 inches longer than the king size. This makes it ideal for taller sleepers. It’s also 4 inches narrower than the king size. If you don’t need the extra length, then you may want to opt for a king mattress and enjoy the extra width.

Sometimes. If you choose the extra soft and super stretchy Purple sheets, you can use the same set for a king bed or a California king bed. Purple sheets are engineered specifically to unleash the comfort of a Purple mattress. The extra stretchy fabric and the Purple Grid™ are a match made in mattress heaven. Our sheets allow you to sink into the mattress with zero resistance so you experience the full body-cradling comfort of the Purple Grid. Purple sheets are light, airy, and silky smooth, which enhances Purple’s signature zero-gravity feel. 

We can’t say the same about other sheets. Stiff king size sheets with no stretch won’t be as versatile and may not be compatible with a California king size mattress, especially if it’s a fitted sheet. To get the most out of your mattress and ensure a good night’s sleep, it’s always best to choose stretchy sheets

Yes, you can use the same pillows for a king bed and California king bed. When you get a new mattress, pillow size is not nearly as important as the size of your bedding or bed frame. The best pillows are the ones you find most comfortable, which often depends on your sleep style. For example, a side sleeper would probably prefer a higher pillow, because their head needs to remain elevated to stay aligned with the neck and spine. A stomach sleeper or back sleeper may want a low-profile pillow to help keep their neck straight.

In terms of comfort and support, you can’t beat Purple Pillows. The original Purple Pillow is made with a Purple Grid™ core, so your head and neck get the same cool, plush, cradling support as your body does on a Purple Mattress. It’s a low-profile pillow perfect for everyone. Optional risers are available to make the pillow taller, which works great for side sleepers. 

The Purple Harmony pillow is the luxurious pillow featuring the new Purple Grid Hex combined with a Talalay latex interior. It has a plush, hypoallergenic core that won’t collapse or bunch. The Harmony pillow is available in two different heights: The standard size is 6.5” thick, while the tall size measures 7.5” thick.

California king beds are recommended for people who are quite tall. This makes sense because the Cal king is the longest mattress you can buy. King and queen beds are 80 inches long, which is typically long enough for most people. The California king is 84 inches long, providing extra leg room for those who are 6’ 6” tall or more.

There are other reasons for choosing a California king bed size over a king size bed. Some average-sized sleepers may choose a California king because it better suits the shape of their bedroom. If your master bedroom is long and narrow, a king mattress may not leave enough room on either side of the bed. A California king may fit better, allowing you to enjoy a large bed without downsizing to a queen mattress.

If you have pets that sleep at the end of your bed, you might benefit from the extra length a California king size mattress provides. Though, we can’t promise it will stop your cat from attacking your toes at 3 am.

No, you don’t need a box spring to support your California king mattress. In fact, we advise against it, especially if you have a Purple Mattress. Box springs lack durability and can be popular homes for mold, bacteria, and dust mites. The squeaky springs will also prevent you from enjoying the full benefits of the Purple Grid.

A California king size mattress gets the best support from a Purple bed frame. Not only do Purple bed frames look great, but they are designed to enhance the luxurious comfort and support of your Purple Mattress.
