What is a California King?

A California king bed is slightly narrower and slightly longer than a standard king size mattress. 

Your California king will be 72 inches wide; a standard king mattress is 76 inches wide. California king beds offer more length; these beds are 84 inches long, rather than the 80 inch long standard king size mattress. 

If you are taller than average or you have pets that sleep with you, a California king could be exactly what you need.

King Size Mattress In inches, the 76 inch by 80 inch is 6,080 square inches. The 72 inch by 84 inch

California King Size Mattress is 6,048 square inches. 

Memory foam or hybrid California King Size is ideal if you need the sleeping space of a King Size Mattress but also need space around the sides of the bed. 

For example, if you invest in a platform bed with drawer storage, the narrower California King may make it easier to get to your belongings.

Differences Between a King and a California King Mattress

Your size preference and co-sleepers will have a big impact on your choice. A standard king is 76 inches wide and 80 inches long. Your California king is 72 inches wide and 84 inches long.

Length

If you’re tall, the California king may be more comfortable. Even if you’re not tall, if your pets sleep near your feet, a California king may still be best.

Width

The standard king is 4 inches wider. If your co-sleepers are restless or like to sleep beside you, a standard size may be a much better option.

Of course, the California king isn’t the largest king mattress option on the market. If you need more space, the

  • Texas king is 80 inches by 98 inches or 54 square feet
  • Wyoming king is 84 inches by 84 inches or 49 square feet
  • Alaskan king is 108 inches by 108 inches or 81 square feet

In square feet, the California king is just 42 square feet. When making your king mattress choice, make sure you also factor in bedding costs and access; you will need clearance all the way around any of these beds on laundry day. 

You will also need to focus on access to your sleeping space and the weight of these mattresses; many will be available split, but these beds will not be an easy move.

Things to Consider Before Buying a California King Mattress

Comfort

Your primary consideration when selecting your California king needs to be your density or firmness needs. If you sleep with a partner and you have different density needs, you may want to look at one of the mattresses with a pressure-relieving layer. 

The more you compress the mattress, the more support you receive. Plushness doesn’t necessarily mean support. You can also increase the density of your support by purchasing an air bed that will pressurize your side of the mattress.

Size

These are large beds. If your bedroom is not large, you may be happier with a smaller mattress that allows you to walk all the way around the bed. Making the bed while you’re kneeling on it can be tough on your body. 

If you have the room, a California king can be a great blessing; you have room, your pets can snuggle up at your feet. Finally, if you’re all under 6 feet tall you can sleep sideways and have room for the whole clan!

Price

You can spend from $500 to $2,000 for a quality California king. Many of the mattresses linked above can be purchased over time by financing directly with the manufacturer. 

Additionally, the mattresses in this listing offer a warranty and a decent stretch of time to test drive your mattress. There are 365 nights in a year. At $5.00 a night of great sleep, you can buy a mattress with a 15-year warranty from Saatva. Worth it? Absolutely!

Weight

California king beds are large; none of these will be terribly light. However, if you need a mattress that will be easy to move on your own, memory foam is probably your best choice. Once your king mattress is in place, the lifting will be worth it!

Portability

Several of the California king mattress options in this listing come with handles built in. Be aware that your mattress will show up rolled up in a box and may need to breathe once you unbox it. Even gel memory foam can outgas; a full memory foam mattress may need to breathe even more.

Temperature Regulation

The best California king for hot sleepers may well be the GhostBed. If you are a back or tummy sleeper, the best cooling California king will also be fairly firm and low loft. 

Avoid a plush mattress unless you have specific pressure relief needs. For those who have struggled to find a California king size mattress that stays cool, consider buying in early summer so you can use your 100 or more night sleep trial to make sure your bed will be cool enough when the days heat up.

Access

Try to settle your California king so you have a 30-inch walkway around the bed. Crawling over your sleeping partner will be challenging. Changing the sheets without having access to the side of the bed will be nearly impossible. 

You may be able to put the 84-inch side against the wall and still get to both ends of the bed for easy linen changes on laundry day.

Storage

There is a lot of real estate under a California king. If you need the space, consider pairing a taller platform with your new mattress. Make sure you get a platform with center support. Invest in bins that will fit under the bed without getting too close to that center support to avoid getting hung up under the bed. 

Consider bins with rollers or casters that will give you more flexibility; bins that will fit under this bed will be long and dragging them out will get old.

California King Mattress Types

Foam

A foam mattress is generally built of layers, some of which may be latex foam. These mattresses tend to hold heat. 

However, a good-quality foam mattress with top layers that will allow air to move can help you get past that overheating challenge. The bottom layer will generally be quite dense and increase the durability of the mattress. 

Often, a foam mattress will be cooler and more comfortable with a layer of latex foam.

Latex

Latex foam is made from rubber and boosts the support offered by the mattress. If you like to be cushioned but don’t care to sink into your mattress, a latex foam mattress may be best. 

A full latex mattress can be quite expensive; as a general rule, your latex mattress will be glued to the top of a polyester foam base. 

Be aware that these mattresses can be quite heavy; be sure about your location before you set it up.

Hybrid

A hybrid mattress pair springs with foam. Older sleepers who need more support on the edge of the mattress will really appreciate the outer foam edge of their innerspring mattress. 

If foam mattresses are too hot but you like the “squish” factor, your hybrid will be a step up. The springs inside the mattress will allow for air transfer and the bottom layer of dense foam will protect the mattress from excess wear.

Innerspring

A full spring mattress is more traditional. These mattresses do tend to be much cooler than a mattress that has more foam in the layers. However, if you are a restless sleeper and your partner is a light sleeper, there may be some motion transfer challenges.

Airbed

An airbed offers adjustable densities, often from side to side. If you need to sleep with your head elevated, an airbed can allow you that flexibility. These beds are also a great option if you are a tummy sleeper and your partner is a side sleeper.

California King Mattress Price Range

You can expect to spend $1,000 on the low end. If you prefer an organic mattress or hybrid, the price will go up; at the highest end, you may pay as much as $3,000 for a high quality organic latex California king.

Do take the time to check out the website of the manufacturer that appeals most. Sign up for promotions and coupons while you make room in your budget for a new mattress. 

GhostBed and Puffy in particular offer great discounts and promotions via email. If you need one sooner, check out the financing options offered on most websites.

Great sleep is priceless. If your current mattress is cooking you, flattened to useless, or just not supporting you effectively, find the bed with the test drive time that suits you and take the plunge!

Benefits and Downsides of a California King

Things we like

  • Tall sleepers will love this mattress. It is 7 feet long, so if you’re over 6 feet and have struggled with feet that dangle, this mattress will allow you to enjoy full support from crown to toes.

Not so great

  • You will need a big bedroom or sleeping space for your California king.
  • Additionally, these mattresses are not light.

Several of the mattresses in this review have handles along the side, but if you don’t have enough room to get all the way around this mattress, changing your sheets will be extremely challenging.

No matter your sleeping style, if you sleep with a partner, you will want to get a California king with little transfer from side to side. A restless sleeper who is used to a small bed may become extremely restless once they move to a bigger bed.

If you are changing sleeping factors, you will need a long test drive time to make sure that the following don’t limit your quality of sleep:

  • location
  • bed size
  • bed density

Carefully consider your current sleeping hardware. If you already have a California king and a box spring, review the recommendations of the manufacturer of the new mattress. 

Putting a glued foam mattress on your existing box spring can lead to too much movement, and excess movement may pull apart those glued layers.

When ordering your new bed, do take the time to measure repeatedly. Your California king will need special sheets and a particular platform. Make sure you get the right one. 

Additionally, it’s a good idea to invest in a breathable mattress cover, at least over the top of the mattress. Air and moisture can pass through the bottom of the mattress while you can avoid spills and perspiration from the top down. 

If you love a cup of coffee as you sit up in bed, that extra barrier can reduce your worries.
