To find the best California king memory foam mattress for your preferences and needs, ask yourself the following questions:

Does this Cal king mattress come with a sleep trial?

When you are purchasing something as important as a mattress, you want to ensure that you will be satisfied with your purchase. And, when you shop online, you cannot try the mattress out before you buy it. Thankfully, many manufacturers offer a sleep trial. Find a sleep trial of at least 100 days to make sure that you absolutely love your new mattress after the break-in period is over.

What type of memory foam is used?

Memory foam can be found in three main types: traditional, plant-based, and cool gel.

Traditional memory foam.

Traditional memory foam is exactly what it sounds like and really hasn’t changed much over the years. The original memory foam is made from petroleum-based products and is known for superior pressure-relief as well as poor temperature regulation.

Plant-based memory foam.

Plant-based memory foam replaces a portion of the petroleum products with plant-derived oils in the foam’s manufacturing process. Plant-based memory foams are considered more eco-friendly then traditional memory foam. Also, certain plant oils offer differ benefits to the sleeper. For example, bamboo, charcoal, and green tea based memory foams all offer an improved level of breathability, temperature regulation, and odor control.

Cool gel memory foam.

Gel-infused memory foam is excellent for anyone who sleeps hot or lives in a hot climate thanks to its next-level cooling powers. This foam is infused with a cooling gel that helps dissipate body heat and keep your sleep surface cool.

What is my budget for new Cal king mattress?

It is incredibly important to pre-set a budget before you start shopping for a new memory foam mattress so you can narrow down your options by price when shopping.

Fun Facts About California King Mattresses

Your brain isn’t the only thing that restores itself during a good night’s sleep. Your body also rids itself of dead skin cells, and those cells end up in your pillow, bedding and mattress. To help with this, you should wash your bedding in hot water at least once a week, including your pillowcases. During sleep, other body processes are halted, including the production of urine, which is why you might notice a darker color in the bowl during that first trip to the bathroom each morning. During REM sleep, your body also enters a state of paralysis to prevent moving around while you’re dreaming.

Tip and Advice

Before you start shopping for a mattress, think about what you need. If you have a bad back or other aches and pains, you’ll need support. A mattress that causes you to sink into the bed may only exacerbate your issues. You should also consider how you sleep. If you spend most of the night on your side, for instance, a mattress that conforms to your shape like one made from soft foam could work better for you. Stomach sleepers, on the other hand, will find a firmer mattress less suffocating. You’ll see bounce mentioned quite often with mattresses. There are pros and cons to having that extra bounce. A mattress with less spring can make you feel as though your movements are limited. However, if you sleep with someone else, that bounciness can become a nuisance, with the bed shaking every time the other person moves. Foam offers more cushioning than springs with padding, but it comes with a downside. Foam can tend to increase your body heat, making you uncomfortable while you sleep. For that reason, many manufacturers use gel to cool things off. If you’re ordering your mattress online, keep in mind that some mattresses need time to unpack. Those that come in a box have to be removed and left to gradually decompress over the hours, and sometimes days, that follows. Online mattresses also may release some chemicals after being unpacked. This is known as off-gassing and is common in manufactured products like memory foam. Some people find the chemical smell while this is happening unpleasant, so you may want to unpack your mattress in a well-ventilated room. Open some windows when you can and allow a couple of days before setting your mattress up and covering it with bedding. Keep in mind that different mattresses have varying thicknesses. If you’re buying a California king bed for the first time, you’ll probably need to purchase sheets to accommodate the new length, but also keep in mind that your fitted sheets will need to be made to fit the thickness of the mattress you choose. Also keep in mind that other items you currently use, like blankets, duvets and comforters, might not accommodate the longer build of a California king bed and replace those if necessary. Although California king mattresses can be pricey, you can find lower-priced online mattresses if you aren’t picky about comfort levels. If you’re buying a mattress for a dorm room or first apartment, this is a great way to save money. Durability is important in a mattress, but keep in mind that for optimum comfort, experts recommend replacing your mattress every 10 years. Some mattresses have covers you can remove and wash. If yours doesn’t come with one, you can separately purchase a mattress cover that will help you maintain a hygienic environment. You probably won’t have to move your mattress very often but consider how difficult your mattress will be to maneuver if you rearrange your furnishings or relocate on a fairly frequent basis. Some mattresses specialize in emitting a subtle scent, such as green tea. If you prefer to fill your home with pleasant smells, this may be a good option for you.

What type of hybrid mattress do you want?

It is extremely important to consider the construction of your next hybrid mattress. There are three main types of hybrid mattresses to pick from: True Hybrid: If a hybrid mattress is constructed using only coils and foams, then it is a true hybrid mattress. Here at Mattress Advisor, we find that true hybrids are exceptionally supportive and are best for sleepers who don’t really care for either all-foam mattresses or traditional innerspring mattresses. Semi-Hybrid: Like true hybrids, semi-hybrids feature a base layer of innerspring coils, however, they lack the foam layers. Instead, semi-hybrids use a thick pillow-top cover to help improve the mattress’ softness. These mattresses lack the pressure-relieving power of memory foam, so if that is something you desire then we recommend skipping over semi-hybrids. Foam Hybrid: Foam hybrid mattresses do not have any innerspring coils in their construction; instead, they use a firm base layer of foam topped with other layers of memory and poly foams.

What type of foam do you want?

While shopping for a hybrid mattress, you will find that most of these mattresses use layers of memory foam in their construction. Memory foam is a much-loved material in mattresses because it offers exceptional body contouring and pressure relief. In general, you will find the three following types of memory foam: Traditional. Traditional memory foam was originally made for NASA airplane seats in the mid-1960s. It is made of polyurethane as well as additional chemicals that increase viscosity and density. Plant-based. Plant-based, or bio-based, memory foams replace some of the chemicals in memory foam with plant-derived ingredients. Some of the most common plant-derived ingredients include bamboo, charcoal, coconut, soy, and other plant materials. Also, different plant-derived ingredients offer different benefits. For example, both green tea and charcoal have excellent odor blocking properties, while bamboo foam has a far higher level of breathability. Plus, this type of foam is manufactured with a smaller footprint than traditional memory foam. Gel-infused. Cool gel memory foam is the perfect option for anyone who wants the comfort of memory foam but finds that memory foam mattresses sleep hot. This type of foam features a gel infusion that disperses a sleeper’s body heat and keeps the mattress cool to the touch.

How firm do you prefer your mattress?

The firmness level of your perfect California king hybrid mattress is completely based on personal preference. Hybrid mattresses typically offer between a medium to a firm-feel and the manufacturers list the firmness level, however, to gain a more accurate understanding of a mattress’ firmness, read the customer reviews.

  1. The split design of Avana California King Mattress allows for easier placement and removal between mattress and box spring. The full-bed length provides additional mattress stability and supports enjoying the full comfort. As for odor – the only solution is to let the mattress outgas for a few weeks. If there is somewhere outside you could put the mattress on, that would be best. Eventually, the smell will go away.

  2. I now have two of Hybrid Medium-Firm California King Mattress by Linenspa in my home for my two children, I just laid a bedsheet in the driveway and inspected the vacuum-sealed wrap – just a nice clean beautiful mattress. No issues now, kids happy!
