    What is a California King Size Mattress?

    A mattress with California King Size Bed Dimensions is infamously presumed to have a larger surface than its eastern cousin the king-size mattress but that is not true. Infact, though the cal king is longer ( 72 by 84 inches) than a king-size mattress (76 by 80 inches), it has a smaller surface area than the easterner.

    King-size mattress = 76 * 80 = 6,080 square inches

    Cal king-size mattress = 72 * 84 = 6,048 square inches

    Fun fact: It is a mattress preferred by the famous NBA players who need longer than standard size mattresses to support their height as well as bodyweight for a good night’s sleep.

    Pros of a California king-size Mattress

    A cal king size mattress is supremely large, able to fit unusually tall adults, a couple and their child or a couple and their pet.

    Even if you are Goldilocks, the ‘big bed of papa bear’ will also feel ‘just right’ because it has a cal king mattress on top! Like Goldilocks, you too can enjoy the many benefits that a cal king mattress has to offer.

    Great for Really Tall People

    As we mentioned, a cal king-california king-size bedsize mattress is the favorite among top NBA players who enjoy the extra inches in length that allows them to sleep properly on their beds without their feet dangling at one end or their head hitting the frame all night long.

    Ample Space

    If you are someone who likes to stretch out while asleep or absolutely need the room (like many) all through the night, going for a mattress with California King Size Bed Dimensions is the right way to go. It is larger than two twin XL mattresses placed together. So unless you are a starfish sleeper, you and your partner (if you are co-sleeping), will have plenty of room to accommodate regular body movements without cramping and also a pet if you want.

    Encourages Motion Isolation

    If you are co-sleeping, chances are that you and your partner have different sleeping habits. While you are able to deal with most of them, their restlessness is disturbing your sleep. A is the right option for you as its size dissipates the movement and encourages motion isolation that helps you stay unaffected by your partner’s marathon activities.

    Enhancing Blood Circulation

    Remember how sleeping in awkward positions as a kid led to funny ‘pins & needles’ sensation? Well, this sensation is attributed to lack of blood flow which is very much a part of the adult human body as well. Sleeping on a california king-size bed can help your body open instead of constricting it and avoid any chances of pressure on your body and blood flow restriction.

    Aesthetically Pleasing

    Since this mattress was developed keeping in mind the big Californian homes, there was no compromise on style and as a result, placing this bed size in your room can amp its aesthetic levels and add a visual appeal to private space.

    Give Your Pressure Points a Rest

    Your shoulder blades, lower back and other regions are the pressure points that are most affected by a lumpy or small mattress as you’re constricting your body to fit in the small space. This adds strain to your pressure points that leads to aches and pains in the morning.

    Cons of a California king-size Mattress

    Even the king is not perfect. So while a California king size mattress has a lot to offer to its users, there are a few drawbacks to look out for before you make that investment.

    Hard to Find Accessories

    Not everyone is extraordinarily tall nor all have huge spaces to accommodate a mattress with California King Size Bed Dimensions. Since its clientele does not exactly signify a big number, its accessories are a pretty rare find.

    Scores Low on Mobility

    Due to its sheer size, it is really difficult to move it around, much less on a regular basis. So if you are someone who is constantly on the move and shifting homes, it is better to go with a smaller alternative as moving this big boy around will be one heck of a task!

    Requires More than a Standard-Size Room

    A California size bed will not fit in any room less than a 13 feet by 19 feet dimension. Although you can tweak those numbers a bit there is no doubt that your room needs to be substantially bigger than an average size room if you want to enjoy the benefits of this mattress.

    Heavy on the Pocket

    This comes as no surprise since a California size mattress is super long, is made from the finest of materials (considering its origin) and requires extra hands for logistics & transportation. All these extra factors cost money which makes this mattress a tad bit more expensive than usual.

    Great for really tall people.A little heavy on the wallet.
    Its great size allows the body ample space to stretch.It is not meant for mobility and hence people who move around a lot should avoid it.
    Since the sleeper can stretch out wide, there is no constriction of blood-flow.Its accessories are hard to find
    Your sleep remains undisturbed, thanks to motion isolation.Requires a much bigger room.

    Points to Consider While Buying a California king Size Bed

    Before you dive deep into your mattress purchase, here are some points you should keep in mind to avoid inconvenience in future:

    Consider Your Budget

    Buying a California king-size mattress is not an inexpensive affair. The size and materials can cost you a pretty penny. You can either check your budget for the same or even finance it via EMIs or credits.

    Consider Sleeping Patterns & Activities

    Do you sleep with a restless partner? Or, are you that restless partner? Then you can use the size of the California king-size mattress to spread the weight around and allow motion isolation to work its charm.

    Consider the Room Size

    Though a California king-size mattress is aesthetically pleasing, it also takes up a lot of space which can restrict movement in your room if it’s not the right size. An ideal room to accommodate a California king-size mattress is 13 by 19 feet. You need to ensure that your room does not cooped up by placing this mattress.

    Consider Your Shifting Activities

    If you are someone who is shifting homes or on the road, buying a mattress with California King Size Bed Dimensions is not exactly a convenient option. You can make logistics easy by going for a smaller size mattress.

    What to Look for While Buying a California king-size Bed?

    • Size – The most obvious things to go for first. While buying a California king-size bed, you need to check the size and also verify whether it complements your sleeping style or height or not. Assessing this parameter can help you make the right choice.

    • Trial Period – Spending at 1/3rd of your life on a bad mattress seems like such a waste of time. You must insist on a trial period. Ask your retailer about the trial period on the California king mattress of your choice. Life is too short to sleep on a bad mattress.

    • Warranty – We have established a California king-size mattress is a pretty heavy investment. Therefore, it is important that you protect your investment with a warranty period. This warranty period protects you from paying for repairs or all-together a new mattress. Certain natural and unavoidable situations can be considered for warranty.

    • Material – Most users are a bit heavy-weight and quite tall. This might lead to more abrasion and hence, wear & tear. However, if your mattress is durable, then you can save your mattress from premature damage.
