Twin are single beds that fit more easily in a small room and they are the most common choices for children. To be exact, No! Two twin mattresses cannot make a king mattress. You must have heard about people fussing two twin mattresses together and making them look like a king mattress.

One fault with this combination is that there is a smaller sleeping surface compared to the king mattress. Let’s see why we cannot have a king mattress from two twins.

Briefly looking at the categories of bed sizes common to many bedding material manufacturing company, most products fall into the size category of Twin size, Twin XL size, Full size, Full XL size, Queen size, Split queen size, King size, Split king size, California king-size, and split California king size. If you observe the list closely you will notice that there are two twin-size mattresses, the regular twin and the extra-long (XL) twin which is 6″ longer than the regular twin size.

To explain what we have above, let’s learn a little about bed dimensions. Here’s the thing, the king mattress measures 80″ in length and 70″ in width. The regular twin mattress measures 75″ in length and 39″ in width and the implication of this is that when you join the twin mattress together, you will still need an extra 5″ in length to make it work. With this deficiency in the twin mattress, you cannot have a king bed by using two twin mattresses.

Meanwhile, the twin XL can do the trick. Nonetheless, it is better to go for a king-size mattress and get over trying to convert a twin into a king. But if you are obsessed about having a king mattress by tweaking the twin size bed then this suggestion on how to work with the twin XL will come in handy. The twin XL is 5″ longer than the regular twin mattress making it the same length of 80″ with the king mattress so your feet don’t have to dangle when sleeping on it.

Before going ahead with this tweaking, here is some information to take note of. Most importantly you need to check the frame width of your mattress. The standard width measurement for the twin XL is 38″ however, some twin mattresses are 39″ wide. Don’t make the mistake of mixing up different sizes.

Secondly is to note the thickness of the twin XL mattress you will be using. You don’t want to sleep on a king mattress that makes one of your sides tilt right? If the twin XL mattresses don’t have a uniform thickness, you won’t have a king-size or better said, you won’t have a king sleep. Take into proper consideration that they must have the same thickness, this way you are ensured a level sleep surface.

Those are just the precautions right? Let’s go to the main business. You start by bringing both twin XL mattresses together and fill the gap between the two beds. Luckily you can get a bed bridge online. Once you’ve done that you are ready to sleep on your tweaked king size mattress.

Don’t forget that two twin mattresses cannot make a king size mattress and what we did is just only improvising on the twin XL (extra long) and not the regular twin size. No matter how badly you want to tweak your twin size mattress into a king, it is yet better to save up and get a king size mattress and save yourself the stress of improvisation and if it is not a problem to you, Good luck.

It is understandable for us to want to have a taste of how it feels with one of these luxury sleep buddies but quite on the contrary, it would have been better to just stick with it now and hope we get them when we can but Hey! I’m not kicking you out from enjoying a California king experience.

It’s no more news that there are different types of mattresses varying in size either slightly or largely. Before proceeding to answer this question, let’s have a look at the dimensions of the fell size mattress and the California king size mattress.

The full-size mattress has a 54″ wide ” x 75″ long while the California king mattress has a 72″ wide x 84″ long. Looking at these measurements, it is obvious that the full-size mattress will not make a California king size mattress. Yes! The answer is a No! You would not get a California king from two full beds. Well, I’ll need an argument to support this answer which will follow.

Let’s start with the dimensions of the full bed, wider than the twin by 15″, it is a bit manageable by two persons leaving only 27″ of sleep space for each. The full-size mattress is also suitable for single persons not taller than 5′ 5″. Putting these beds side-by-side, we have it all summing up to be 108″ wide which is way too wide for a California king size mattress with only 72″ wide and 84″ long.

With two full-size beds, you get 54″ of sleep space for each person which when compared to the California king, leaves you with an extra 18″ sleep space to make it super wide. So, if you are considering tweaking this one, be sure to know that you cannot have a California king either with the length or width and if you feel a pressure from your partner to get a wider bed, then you may want to save up and purchase a standard King size which will give both of you an added sleep space of 11″ plus a 5″ long and you won’t have to worry about a thing. You can also go for a split king if it’s okay for both of you to spend the night apart.

Here’s a suggestion on how you can find the mattress that best fits you. In my opinion, improvising one of those tiny mattresses into becoming large ones is not my thing so I will only stick with suggestions that I feel would do just the perfect trick.

If you operate a high budget, you may find the California king handy and probably use it until you get a partner. But if you have a somewhat low budget, you may resort to the twin XL to meet that king-size you need or better get a queen size mattress. And if you are bent on changing your mattress, some considerations have to be made about your room size, bed frame, and of course, your purse.

When using the full-size mattress no longer gives you all the comfort, you may opt-in for the queen or king size and if you are not bothered about the extra-wide 108″ double full-size mattress, you can go all ahead flank to adjust the full bed. None of these still gives the comfort and smoothness of the California size mattress.

Headboards are good and serve an aesthetic purpose to make your bed beautiful and also provide support for your back when sitting up in bed so you don’t flip backward. These beauties help adorn your bed with a royal look.

Deciding if you should use your king headboard for your newly bought California king bed may require you to purchase the bed claw conversion kit by checking it up on Amazon or other online stores.

The bed claw comes with a double bed hook bracket, a 6″ length, outside diameter of 1 ⅝” and an inside diameter of 1 ⅛” deep, allowing you to use the king bedding with a California king headboard, or vice versa. What you have to do is get one for yourself and attach it to your California king bedpost and attach your bed rails to the hook slot on both sides of the bed claw.

An alternative way to the bed claw conversion kit is by manually fixing the problem. Since the king mattress and the California king are quite similar, you can adjust the headboard size by chopping off the excess part to fit your California king mattress.

If you love experimenting, you may find this aspect helpful as it will take you through how to manually convert (adjust) your king headboard to fit your new California king bed. One of the most commonly used headboard material is the wooden headboard and if you have one of these, you can easily use a saw to cut it to the side of your taste and since the wooden headboard can easily be painted, you can retouch it or better still attach other materials like metal to make it look just perfect.

Another type of headboard used is the padded headboard and trying to make a manual adjustment to this type may run you the risk of damaging the covering on it unlike the wooden headboard that can easily be repainted, once the padded headboard is damaged, there is technically no way to all-by-yourself salvage it. In this case, it is better to consult a professional carpenter on how to go about it.

What about headboards with shelves or drawers? Cutting headboards like this can be puzzling because you want to be sure you don’t end up slicing off your drawer. A simple way to make this adjustment is by first disassembling the headboard (taking apart the drawer and shelf) then cutting the same way you would do for the wooden headboard then reassembling. One limitation that follows this adjustment is that you may need to buy extra wood to finish the work and make it look fit for the California king mattress. Giving it a second thought, why would I go through all these stress when I can always get a new California king headboard online? It’s totally up to you.


The time to enjoy a luxurious sensation is here and with the California king mattress, your night comfort is certain.

If you are on the look for a mattress that gives you good edge support, contour support on your back – evenly district your body pressure and at the same time very responsive and adaptive to temperature, trapping away your body heat to give a cool night, the Zinus Gel-infused hybrid mattress will come in handy.
