Before starting with the task, there are a few things that you will need to join two single mattresses.

Essential requirements

Optional requirements

If you are buying single mattresses to join as one, then buy two twin XL mattresses, not two regular ones. If you join two twin XL mattresses, it will have the exact dimensions of a king-size mattress. However, if you already have two regular twin mattresses, you can also use them, but you may face some trouble fitting the mattress on your king-size bed.

Once you have all the required things, follow these steps to learn how to join two single mattresses together.

Check Out The Compatibility Of The Mattresses

If you are joining two mattresses that you already own, then you need to check their compatibility. The mattresses need to be of the same thickness and same length. If the mattresses are of the same type, it is even better.

For instance, if you are using an innerspring mattress and a memory foam mattress together, it will feel different. You can invest in a new single mattress of the same type as the one you own. Unless, of course, both the partners need different mattresses.

Set Up The Base For The Mattresses

The next step is to set the base for keeping the mattress. Next, you need a king-size bed frame to accommodate two single mattresses. All the bed frames come with instructions on how to set them, but they eventually have the same steps.

The steps may differ if your bed frame is wooden or you have customized it.

Place The Mattress And Secure It

Now that you have set the bed frame, you can place the mattresses on top of it. Take the help of your partner and place one mattress at a time and align them in the center of the bed frame. If you use a metal bed frame, your mattresses will slip on it. You can add a grip pad to prevent your mattress from slipping. You will need to place the grip pad on the bed frame before the mattresses. 

If you don’t want the mattresses to slip away from each other, you can add a mattress connector strap. After you have aligned the mattresses, you need to put the strap on the outer edges of the mattresses to keep them together.

Place The Bed Bridge

Although if you use a mattress connector, there is no need for a bed bridge, some people still prefer to use it. A bed bridge made with soft foam material goes inside the middle of the two mattresses. Adding a bed bridge covers the gap between the two mattresses.

People who move around their bed or like to sleep in the middle will benefit from a bed bridge. You will not feel the gap when moving from one bed to another. However, you will still feel the raised section in the middle of the bed.

Put The Mattress Protector

Once you have the mattresses secured in place, the next step is to put a mattress protector on top. Not only will it protect your mattress from accidental spills, but it also hides the fact that you have joined two mattresses. Also, the additional layer of mattress protector will make the bed bridge less noticeable. 

Put The Sheets

The next step is to put your fitted sheets on top of the mattress. A king-sized sheet will fit perfectly on two twin XL mattresses. However, it will not fit as great on regular single mattresses.

Fill The Extra Space By Adding a Headboard

If you are working with two regular size single mattresses, chances are, after joining them on your bed frame, there is about 5 inches of space left. An upholstered headboard can fill up the extra space. It is important to fill the extra space.

Otherwise, the mattress will move when you try to sit or sleep in it. Even if there is no extra space, adding a headboard will enhance the look of your bed.

While using two mattresses to make a bigger space, the biggest problem you will face would be keeping them from sliding away from each other. However, there are a few ways you can do this.

Conclusion

Whether you are shifting with your partner or want some extra space for yourself, you can easily apply this trick of how to join two single mattresses together.

However, only pushing the two mattresses together is not enough, and you may end up with gaps between them. You need to make extra efforts to secure the mattresses together for a good night’s sleep. 

While joining two mattresses may not replicate the comfort of a king-sized bed, it saves you a lot of money. Remember to select twin XL mattresses and fill the gap with a bridge; you will have double the space you had before.
