Firstly you need to know how much size or dimensions of the mattress you would need to fit your place. You don’t have to cut it without measuring. Take a measuring tape and then attentively measure the area where you want to fit the mattress.

Take a Marker and Ruler

Now you have taken the measurements of the place where you want your mattress to fit. Now you need to take a marker and mark how much you need to cut your mattress but make sure to have some margin while drawing the lines with the marker. 

Because those marked lines would help you cut the perfect size that would fit into your place and avoid any kind of miscutting, it will save you time and, most importantly, money. 

Size of the Mattress

The mattress size is very important, and when you need to cut the mattress, you should know the different sizes of the mattress because that would help you determine how much you want to cut from which size of the memory foam. 

There are mattress types according to size, and every mattress has different dimensions. For example, the twin mattress type has a size of 38” x 75” and the twin XL has a size of 38” x 80”, the size of the full-size mattress is 53” x 75”, and the queen-size mattress’s dimensions are 60” x 80”, king size mattress’s dimensions are 76” x 80” and the California king size mattress has the dimensions of 72” x 84”.

Remove the Mattress Cover

When you know all about the sizes and dimensions that you need to cut the mattress, you have to remove the mattress cover before you start cutting your mattress. There are many mattresses whose covers are fixed, and you need to cut them to open them.

Remove the Mattress cover

When you start cutting, you need to make sure that your saw is straight and prevent it from moving while cutting because that will also damage the shape of the mattress, you need to cut the mattress with a straight saw while holding it very tightly. 

When you cut the mattress, make sure you are doing it on a clean flat surface because that will provide you very hard support and prevent the saw from moving. Three methods are practiced while cutting the mattress that we’ll mention and explain below:

But not everyone has access to this kind of big business saw so, firstly we would recommend you to go to this shop where professionals will cut the mattress with you, but if you want to do it yourself, then you need to find this large saw and then cut the mattress horizontally with it but very carefully. 

Using Hot Wire

This is also a very good technique to cut the mattress horizontally, but if you are someone who does not have a good time and very limited space, then you should avoid this method to cut the mattress because time and space are the two important things in this cutting process. 

Using Hot Wire

In this process, you need to heat the wire to a specific temperature to cut the mattress according to your needs. We suggest that if you are planning to start a business to offer the cutting service, you should use this technique; otherwise, cutting one mattress for your boat might not be very suitable because it would need a very open space and a lot of time. 

Using Electric Saw

This is the easiest and best way to cut the mattress, and in this cutting process, you just need to hold the saw firmly, and the saw will do the rest for you. This electric saw cuts the mattress accurately compared to some other methods explained in this article. But first, you need to do all the things that we have mentioned before.

This is how easy the mattress cutting would be for you with the electric saw but do it with firm hands because moving the electric saw can be very dangerous for you and your mattress.

Also, there are some other materials in the mattress like gel and some others; if your mattress has that, Some people might it hard to cut them compared to memory foam mattresses.
