8 Top Picks - Best California King Mattress

Zinus - Best Odor Control


  • Green tea infused
  • Multilayered structure
  • CertiPUR-US certified
  • Knitted jacquard

In our opinion, the best California king mattress is Zinus.

It’s a fantastic feeling when, at the end of the day, you find yourself in a mattress that is both comfortable and smells divine. This is the feeling you get with this piece of heaven, manufactured by Zinus. The infusion of green tea is what makes this mattress remarkable, and the main reason why it stands out.

This is not to say that it’s the only extraordinary feature it has. This product is made of four layers of foam – three inches of comfortable memory materials, two inches of comfort foam, and another two airflow layers of high-density support foam, the total being 12 inches of peaceful sleep and guaranteed comfort.

All the layers and types of foam have a CertiPUR certificate, which means that they are in accordance with the highest American standards when it comes to foam used. This can be especially important if you suffer from allergies or just want to stay eco-friendly.

Finally, on the aesthetic side of things, this model is distinctive because of its knitted jacquard, which makes it look even more appealing, with several patterns to choose from.

Best Price - Best Pressure Relief


  • Conforming memory foam
  • No pressure points
  • Multi-layered
  • CertiPUR-US certified

By far the most distinctive characteristic of this mattress is its ability to relieve your pressure points. All the foam layers work together to make your weight distributed evenly and give you the well-deserved rest. This also means that your sleeping partner won’t feel any movement from the other side and will sleep equally comfortably, given the size of the mattress and the quality of the memory foam.

The 2.5-inch memory layer is not the only reason for this – there is also a 3-inch pressure relief layer, which is soft and ventilated. The final one is a 6.5-inch high-density support foam, which provides additional balance and support. It’s the combination of these three that makes you feel like floating on air and ensures deep sleep.

All Best Price products have a CertiPUR certificate which means no lead, mercury or other heavy metals. It also means that there are no flame retardants, formaldehyde, or ozone depleters in the finished product or during the production process.

Linenspa - Ideal for Kids' Room


  • 8-inch hybrid
  • Plush memory foam layer
  • Cozy knit cover
  • Conveniently compressed

Linenspa has made this product ideal for a kid’s room or a guest room. It’s an 8-inch hybrid, consisting of coil springs to provide responsive support, comfort foam layer, and a memory foam one. This is an excellent combo for a medium-firm feel mattress, perfectly suited for your kid’s needs in terms of support and comfort.

A huge plus is the memory foam section, which offers not only relief for the pressure points on the body, but also aligns the spine and provides maximum comfort. It has a plush finish, along with a cozy knit cover, which all contributes to the feeling of complete relaxation for your children.

Last but not least, and very practical, too, is the way it is packed. It is compressed and inside a box, ready to be shipped quickly, which is convenient to be carried and set up effortlessly wherever you decide to place it.

Tuft & Needle - Best Bed in a Box


  • Adaptive foam
  • Innovative design
  • High-quality materials
  • Delivered in a small box

Tuft & Needle is a company that ambitiously offers its customers a remarkable experience of sleeping on a brand new type of material, adaptive foam. Its innovative design and structure is what stands out – it is as comfortable as memory foam, but not a heat trap. It also provides bounce and support better than latex or a spring mattress.

The company boasts its numerous certificates of quality such as CertiPUR, Oeko-Tex Standard 100, and Greenguard Gold. All of these promise quality and safety that is above all American or European standards and avoid harmful substances in their products.

Being adaptive is handy for more than just pressure relief and support. It is also convenient when it comes to packing and shipping because this type of material can easily be placed in a relatively small box and delivered quickly to your doorstep.

Classic Brands - Best Pillow Top


  • Coils + gel infused memory foam
  • Pillow top
  • Ventilated design
  • CertiPUR-US certified

This mattress by Classic Brands is a top-of-the-range product when it comes to comfort and breathability. It owes these features to its ventilated design, which prevents traditional memory foam from creating “hotspots” during sleep. The temperature regulation, as well as airflow, are drastically improved compared to standard models.

Other than breathability, this product brings the usual benefits of high-quality memory foam such as pressure point relief, which means sleeping comfortably and waking up without that annoying back pain. Also, the 8-inch innerspring provides excellent support for your spine.

Another thing is the certified quality of the materials used, proven by the CertiPUR-US certification, which means harmful substances aren’t used. It is also covered with a pillow-top knit cover, which is quilted and charmingly detailed; it has corded edges and coordinating knit side panels.

Sleep Innovations - Ideal for Back Sleepers


  • Cooling gel memory foam
  • TriComfort Design
  • Ideal for back sleepers
  • Bed-in-a-box

Sleep Innovations’ Marley line of products offer a delightful combo of foam layers, branded as TriComfort Design by the company. The backbone of this design is the 2-inch cooling gel memory foam, supported by a 2-inch air channel one and six inches of firm support foam. What you get is ten inches of mattress both soft enough to relieve pressure points and hard enough to align the spine correctly.

All of the above-mentioned items are why it is ideal for back sleepers – the spine will remain in a perfect position throughout the night. Also, a cooling gel memory foam mattress will improve the temperature regulation, an issue well-known to all back sleepers. Without back pain, you will sleep longer and wake up feeling refreshed and recharged.

This California king mattress is a bed-in-a-box type, and that means it is compressed up to 20 times compared to its final shape. It can take a day to enlarge fully after unpacking, but the upside is that it is easily manageable and that shipping and delivery is a breeze.

Nectar - Best in Support


  • 2 layers of gel memory foam
  • Great support

Nectar has made an excellent product to provide maximum support but, at the same time, comfort and coolness. The two top layers of gel memory foam in this gel memory foam mattress contour perfectly to your body and provide air circulation. They also relieve pressure and pain by distributing your weight in an even manner.

The recovery foam is the key for support, giving you the ideal bounce and response, regardless of your sleeping position. It is adaptive and has a high core density. Finally, the last layer provides support for the top ones and gives you a stable and breathable foundation.

Why not mention the bonus features with this one? It comes with a set of two premium pillows in the same box.

PrimaSleep - Great Value


  • I-Gel foam
  • Adapts to your body
  • Better ventilation

Have you heard of I-Gel material? Developed by PrimaSleep, it is now perfected into one of the most comfortable and durable materials for mattresses. 

This 12-inch mattress adapts perfectly to your body, and it is an excellent value for the money for this type of mattress. It responds to your shape, size and weight precisely, every time you use it. Unlike many other sorts of material like ordinary memory foam, I-Gel lasts longer and prevents heat pockets efficiently.

The remaining two layers, HD convoluted and Dura HD foam, improve support for your back and the ventilation of the whole mattress. They are 2.5 and 7.5 inches thick, and together with I-gel make a perfect combo for a gel memory foam mattress. Finally, the manufacturer is proud of its Smart package, which offers advanced compressing which ships easily.

Factors to Consider When Buying California King Mattresses

Mattress Type and Size

There are a lot of benefits to this size. To start with, California king is 72 inches (width) by 84 inches (length), which appears more than the King size, but not when you work out the numbers. King size is 76 inches x 80 inches, so you get a slightly larger surface area.

The trick is the length of the California king, which offers plenty of space for people over 6 feet tall. At the same time, it can accommodate two adults, just like king size beds do. In addition, it looks more elegant and spacious because of its length.

As for the type, there are so many options on the market nowadays: spring coils of different types, memory foam, latex, hybrids, and adaptive material such as Tempur. A word of advice: you should always consider your favorite sleeping position and go for the type that promises a good night’s sleep for your kind of sleeper.

Warranty and Durability

Warranty is something you must pay special attention to because you don’t buy a California king every day. The prices can range anywhere between several hundred and several thousand dollars, so you must be sure you are getting the right kind of service, which includes a warranty as well.

Most brands will offer a minimum of 10 years, and you can also find 20 or 30 years warranties. In some cases, manufacturers offer a lifetime guarantee. Read the fine print and don’t be misled into believing that all warranties are equal.

Durability can perhaps best be shown in practice: the longer the warranty, the more durable the mattress tends to be. Also, you should be aware that some adaptive foams last longer than ordinary memory ones and that coil springs, if not well-protected, can be the most sensitive part of your mattress. Check out any review left by consumers and the length of time the mattress has been on the market, too.

And make sure to note if your mattress is supposed to be used with a box spring (although most aren’t).

Support, Comfort and Firmness

Used by tall people more than any other type of mattress, California king must provide appropriate support for people of such size. This means, although coil springs used to be considered as the type that offers the most support, there are many alternatives on the market nowadays. Multi-layered foam could be the answer you are looking for, especially with the bottom level, which must offer high-density and high-quality base support.

Comfort is a relatively subjective feature, but there certainly are brands that offer more. Plush finish or pressure points pockets, several layers of memory or adaptive foam, special covers – all of these should be considered. Comfort is a thing that is easily tested out, so hit the shops or use those long trial periods (typically a 100 night trial).

When it comes to the firmness level, there are several categories such as soft, medium, medium firm, firm, and extra-firm. There is no agreement among the manufacturers regarding the actual numbers that might quantify these categories, so the best way is again testing them out as well as knowing your sleeping position and habits, and potential health issues.

However, a medium firm mattress is often the most widely accessible. 

Mattress Layers

As you may have already figured out yourself, on the market of today, it is all about layers. The thing is that certain characteristics of materials vary so little that the actual question is not the type but the right combination. It is especially true for large beds like the California king mattress.

A typical structure will involve either a coil spring – memory foam hybrid or a memory/adaptive foam – base support foam combo. Be aware of the quality and the width of poly layers in particular. As far as top layers are concerned, be mindful of the total width of memory/adaptive foam and how it might relate to your weight and stature. 

Also, don’t forget about those little perks that might not be little to everybody like infusions, adjustable firmness level or washable, breathable covers. Although not layers as such, they can contribute to the overall feeling of comfort for many people.

California King Mattress Overview

A Brief History

Rumor has it that there was a certain executive back in the 1980s who came up with the idea to make a standard king size longer and narrower because of his own shortcomings. However, the truth is that this type of mattress has been around for probably a hundred years. It is impossible to say who came up with the exact name and dimensions, but it is a fact that beds of similar sizes were first introduced in the golden era of Hollywood of the 1920s and 1930s.

Until the 1960s, there were more than fifty types of mattresses on the market, and many remained nameless. The mass production and the rise of the economy greatly benefitted the king and the California king models. The middle class wanted the best, and what appeared to be the most elegant, so they opted for one of these. The fancy “California” name helped as well, the king size also being known as “the Eastern king.”

What is the Difference Between California King vs King?

The usual misconception is that the California king is bigger, possibly because it became extremely popular decades after the king model first appeared. Another thing is that it merely looks bigger due to its length. At 72 x 84 inches, it is narrower but longer than the usual royal 76 x 80 inches.

They are typically found in master bedrooms, and their functionality is quite similar. In modern apartments, bedrooms are longer so California king could be a better fit than the standard version. Also, couples who like to sleep close to each other sometimes go for this option because of its width.

The price is the only significant difference, especially with some brands. The production numbers of the California king tend to be lower, and therefore it is slightly more expensive to make one, It reflects on the final price of the product which can be up to 15-20% higher than the king size.

While memory foam is a form of polyurethane, it has some characteristics that make it a more comfortable option. It reacts to body heat and becomes softer, but otherwise, memory foam mattresses are harder, heavier, and more expensive than those made of ordinary latex foam.

They are, however, desired because they mold to the sleeper’s body, and in the process, they relieve some pressure points, leading to a more relaxed sleep.

PROS and CONS of Using California King Bed


There is one obvious benefit of this model: the additional 4 inches of length. This is why it is the most suitable one on the market for anyone taller than six feet. Also, it fits rectangular bedrooms more elegantly – it simply looks better.

Another thing is that it is usually more luxurious and costs more than any other model, offering perks that another mattress simply does not. The luxurious look makes it feel glamorous, justifying its Hollywood name, which may appeal to some people as well.


One of the major downsides is that accessories for California kings are harder to find and typically pricey. When it comes to sheets, the choice of styles tends to be limited and even non-existent in some areas. Unfortunately, this is also true for bed frames and other similar accessories. 

There is one more thing: couples, who are the target market for this product, tend to a buy bigger and wider mattress because people of average size benefit more from the standard king version.

Where to Buy One


The good old traditional stores will probably never become obsolete: there will always be people who want first-hand experience and personal advice. For some, it is an opportunity to chat and get high-quality service that is so common in mattress stores. Objectively speaking, what you get is education as well – you are in the hands of experienced sales representatives who will typically give you a detailed walkthrough (materials, sizes, accessories, etc.)

On the other hand, stores are indeed limited by their surface area, so there are only so many mattress models you can actually try out. Another thing is the profit margins, which tend to be higher in traditional shops than online ones because manufacturers offer their products directly, so prices online are typically somewhat lower.


So, mattresses in online stores are more affordable. But is that the only benefit you get? There are others as well, such as longer trial periods, free shipping, and returns. Another major advantage is the number of items available online compared to the limited supply of traditional stores. You can easily compare them and balance all the parameters without much effort, typically on a single website. 

There are downsides as well, such as not being able to test out the mattress physically, so returns are much more common. Simply put, “soft, medium and firm” does not mean the same thing to everyone.
