The 10 Best California King Mattresses in 2023

Best California King Mattresses - BADGE

Upgrading to a big bed is one of the finest experiences ever!

Mattresses have an unusual characteristic in that they grow together with us. Therefore, mattress updates are crucial as we grow old – from the time we first sleep alone as children to the teen years and eventually adulthood!

Most of us would choose a larger bed if we had the option. It feels nice to sleep like royalty! Plus, having extra room on your bed allows for a better sleep day or night.

There are several common causes of sleep loss when you are in a relationship. One of them is partner disruption. Most couples do not have the same sleeping habits. Some couples experience sleep apnea, which is dangerous. But once you upgrade your mattress size, most of these problems will go away.

Product Highlights:

  • Beautifully detailed quilted pillowtop knit cover
  • Low motion response
  • Self-ventilating 
  • 10-year worry-free warranty
  • Gel Memory Foam
  • Very affordable

Some of you are not planning on spending a fortune or breaking a bank for a new mattress. The Classic Brands may be the one for you! This brand offers high-quality memory foam for a more comfortable sleep at an affordable price.

This California King bed has three layers to make the user feel more comfortable in getting sleep – day or night.

The top layer of memory foam provides the sleeper with the initial level of comfort and contour. In addition, this layer helps with cooling the bed by dispersing heat more evenly across the mattress.

This second layer serves as a transitional support layer. It smoothens the transition from the top layer of memory foam to the previous base layer while also giving support to the sleeper. In addition, this layer of poly foam works in conjunction with the memory foam layer to prevent excessive sinkage.

The mattress’s bottom layer serves as a fundamental and supportive base. It keeps the mattress’s overall shape while giving support and deep compression.

The mattress cover is uncomplicated in terms of appearance. The white top, paired with the solid grey sides, gives a simple yet modern design that many other online mattress retailers have copied.

The feel of a medium-firm to slightly-firm mattress will vary depending on body weight. 

A sleeper weighing 150 pounds or more will feel slightly firmer. This is because they would sink through the top layer of memory foam and into the former layer of transition foam. This category of sleepers will most likely obtain a firmness rating of 7 out of 10. 

The same is true for sleepers approaching 200 pounds but especially for those who are over 200 pounds. These sleepers may compress the memory foam top layer more dramatically. It can result in a firmer mattress, perhaps in the 7.5 to 7.5 out of 10 range.

4. Sealy Hybrid California King Mattress

Product Highlights:

  • 10-year warranty
  • Copperhill-infused foam top
  • Affordable
  • Innerspring & foam hybrid

The Sealy 12-Inch Hybrid Bed-in-a-Box is one of the best California King mattresses. This brand makes buying a mattress with the best quality easier.

This mattress will arrive in a package measuring 16.5 x 16.5 x 44.5 inches. This package is a bit heavy – weighing 60 pounds. A plastic roll is shrink-wrapped around the mattress within.

The mattress has four layers: 

  1. Individually encased coils
  2. Comfort foam
  3. Premium memory foam
  4. A removable cover 

This 12-inch Californa King mattress has a medium-firm feel. The upper memory foam layers of the 12-inch are thicker, resulting in a softer feel level. In addition, the removable zippered outer cover offers a quilted texture on the upper surface.

Because the memory foam layers are only on one side of the mattress, you cannot flip it. However, you can rotate it if you need to in the future. 

The coil layer is different from the rest of the California King mattress. This mattress is made from pure memory foam mattresses and will not make you feel like sinking into it. In addition, the mattress will not retain your body heat, allowing you to sleep cooler. Customers are also blown away by how quickly the mattress expands and becomes usable.

Product Highlights:

  • Freshly poured T and N Adaptive foam
  • Non-toxic Certified
  • Greenguard Gold and CertiPUR certified
  • 10-year warranty
  • 100-night sleep trial

The Mint Mattress from Tuft & Needle has two layers of adaptive, graphite-infused polyfoam over a high-density polyfoam base. This construction builds on the two-layer design of the Tuft & Needle flagship bed, resulting in a plusher feel for the Mint Mattress. 

The top layer offers noticeable contouring. However, the overall feel of the bed is medium-firm, and the polyfoam will not cradle the body or sink like memory foam. It creates a balanced feeling of sleeping on and sleeping in. It will assure you of a comfortable combination of pressure relief and even support.

The Mint has an antibacterial protectant integrated with the cover fabric. In addition, the Mint Mattress’s comfort system has open-cell foams that shouldn’t absorb or retain too much body heat. It makes it an excellent choice for folks who sleep hot on all-foam beds. 

The mattress’s other top advantages are superb motion isolation, above-average durability, and no noise when bearing weight. In addition, it provides enough support for most sides and back, even for heavy people (up to 260 pounds), thanks to its medium-firm texture.

This brand of California King mattress is a budget-friendly bed. But despite its affordability, it does deliver a high-quality California King mattress.

8 - California King Mattresses

Product Highlights:

  • CertiPUR-US Certified Foams
  • Worry-free 10-year limited warranty
  • Affordable Price
  • Easy delivery
  • ViscoLatex technology

With this go-to quality, Zinus does it again. As a result, it has much positive feedback from real people who like the price and the performance.

For optimum back and pressure point support, Zinus starts here with ViscoLatex technology. Verified reviews believe this memory foam is responsive and the ideal firmness for the whole family. To cap it off, it’s 12″ tall and thick.

This latest option from Zinus combines all of the technology buyers expect with an inexpensive pricing point. In addition, if you choose, there is a free haul-away option for your old mattress.

For convenient shipping and setup, the manufacturer compresses the Zinus Gel-Infused Cali King mattress. Meanwhile, it’s CertiPUR-US certified, which means it meets the most stringent safety requirements –– something that buyers appreciate.

You should feel the responsive support in one of the cushions of this bed. Its upper layer feels like the softest pillow you have ever had. However, its softness does not hinder comfortable neck support. It also has contoured high-quality density foam and innerspring coils.

The springs and foam combine to make this bed ideal for couples and combination sleepers. The bounce is ideal for adult activities and changing positions, while the foam dampens motion transfer.

9. Live & Sleep Classic California King Memory Foam Mattress

9 - California King Mattresses

Product Highlights:

  • Eco-Friendly
  • Full refund guarantee from the 30-day trial
  • 20-year warranty

If you plan to share your mattress, this is one of the most crucial considerations to keep in mind. When applied with heavy weight, the Live and Sleep Classic Mattress structure responds nicely. 

The disruption on the other side of the bed changes one drop of a 10-pound ball at various heights. For example, dropping the ball from a height of 4-8′′ causes minor disruption. However, if dropped from a height of 12 inches, expect worse disruption. 

Regardless, the memory foam and TriSupport technology did an excellent job of preventing motion transmission throughout the entire surface.

You will be happy once you hear the temperature of the mattress. Memory foams can trap heat. As a result of the trapped heat, people sweat while sleeping. 

However, with a few more materials, such as those found in the Classic Mattress, this is no longer a problem. In addition, LiveandSleep developed its stretch-knit cover light and airy to prevent the mattress from trapping heat.

Even in the summer, the cover keeps the mattress cool and comfortable. Its comfort layer also has an open-cell structure, making it more breathable than traditional memory foam.

10. Novilla California King Mattress

Product Highlights:

  • Bamboo Fabric Cover
  • 4 Gel-Infused memory foam, comfort layer
  • High-density foam
  • Warranty: 10-year limited, 30-day money-back guarantee
  • CertiPUR-US Certified

The four layers of Novilla’s gel memory foam mattress provide maximum support and cooling as you sleep. 

The first layer is gel-infused memory foam, which keeps you cool while keeping you comfy. The support foam is fashioned like an egg crate to allow for improved ventilation during the night. It absorbs heat to go in and out and prevents overheating.

This bed uses bamboo to make the cover. Regardless of the ambient temperature, this fabric wicks moisture away from the body and keeps you dry at night. As a result, it’s ideal for night sweats.

Your weight is evenly distributed throughout the surface, thanks to the comfort foam. Two layers of high-density comfort foam are present. These layers help to keep the mattress’s strength and support for long-term pain treatment and comfort.

You won’t roll off or have difficulties getting in and out of bed since the mattress resists sagging and gives edge support. It arrives in a box, rolled and squeezed. It’s best to allow 72 hours to air out and reconfigure itself.
