What Makes a Great California King Mattress?

Did you know that 68% of Americans struggle to sleep at least once a week? There’s a very good chance that you fall into this group of people.

Many people don’t realize it, but your mattress makes a huge difference in your sleep quality. Of course, you should go for the largest size possible (such as a California king mattress) so you have plenty of room to stretch out in.

But what else should you look for?

In this article, we’ll discuss the details of a California king so you can make the best decision when it comes to mattresses.

How Big Is a California King Mattress?

The first thing you might be wondering is: what are the dimensions of a California king mattress? Do note that they are not synonymous with standard king mattresses, as they have different dimensions.

Regular king-sized mattresses are 76 inches wide and 80 inches long. Basically, they’re 2 extra-long twin mattresses combined together and give you an almost-square mattress. This makes it harder to fit in some bedrooms so make sure you have space first.

On the other hand, California king mattresses are 72 inches wide and 84 inches long. So while there’s not that big of a difference in size, it does make it easier for you to fit this mattress in bedrooms, as it’s a little bit slimmer.

What You Should Look for in a California King Mattress

Now that you understand the difference between a standard and California king mattress, plus its specific dimensions, the next thing is to find out what you should look for when shopping.


As with all mattresses, California kings come in a variety of firmness levels. You can get anything from a soft to very firm mattress, depending on your personal preference.

In general, if you like to sleep on your side, you’ll want to get a softer mattress. This ensures that your spine is aligned and your shoulders and hips are cushioned when you lie down to sleep.

But if you like to sleep on your stomach or back, then we’d recommend getting a firmer mattress. If you’re of a heavier weight, you should also opt for something firmer.

Because all mattresses naturally become softer over time, you might want to go with something a little bit firmer than you’d like. That way, you won’t end up with a Cal king mattress that’s unusable within a few years’ time.

Temperature Control

Perhaps you and/or your partner run hot when asleep. Even if you use the thinnest of blankets, you wake up sweaty, especially in the summertime.

Not only can this cause you to be uncomfortable, but it can also ruin your quality of sleep. As a result, you’re not as well-rested as you can be.

An easy way to solve this is to look for California king mattresses that utilize the best of today’s technology. For example, the TEMPUR LuxeAdapt mattress has the SMARTCLIMATE Dual Cover System, which gives you a cooling sensation when you lie down on it.

You can also get temperature control mattress protectors. Not only are these waterproof, but these also use the latest technology to keep you cool all throughout the night.


To get a great night’s sleep, you need to get a California king that’s made up of various layers to provide you with comfort all throughout the night.

As we’ve mentioned above, many have a layer where it helps keep you cool. There’s also usually a memory foam layer, as well as a comfort layer. These work together to ensure the bed’s firm enough to keep your spine aligned, but soft enough to let you drift off easily.


Generally, you have 3 different styles to choose from: traditional spring, foam, and hybrid. While foam mattresses offer better support than traditional spring ones, they do tend to hold onto heat more, which is bad for people who run hot.

A good compromise is the hybrid mattress. Hybrid mattresses have multiple layers for support and comfort including foam with inner springs. The foam layers offer pressure relief while the inner springs provide added support.

You can also get various styles with your mattress by picking specific bases and adjustable bed frames. Not only do these allow you to get more comfortable, but they’ll also let you show off your style.


You will want to get a mattress that will be worth your money. While a cheaper mattress can be attractive, buying from a small brand you’ve never heard of will most likely be an unwise choice.

Try to stick to bigger brand names that have proven reputations. While their products may cost a little more, you’ll have peace of mind knowing you’re getting top-quality mattresses.
