How To Cut A Memory Foam Mattress

What Are The Required Tools To Cut Your Mattress?

The following list will show you the tools you will need to cut your mattress:

Long Serrated Bread Knife

A long serrated bread knife is the ideal tool for cutting the memory foam. This is because it's long and narrow, so you can cut deep into the mattress without it curling up or folding.

Electric Knife

If you're cutting a thick mattress, an electric knife will be very helpful. This tool produces a sawing action that cuts through the foam VERY quickly.

Extra-large Scissors

Extra-large scissors can also get the job done. If you're cutting a lot of foam, the bigger the tool, the easier it is to cut through.

Tape

To make sure the cuts are even and straight, you'll also need a tape for measurement.

Cutting Board Or Surface 

For safety reasons, it's best to cut your memory foam on either a hard surface (like wood) or cardboard (or other wood substitutes).

Steps To Cutting Your Memory Foam Mattress

When it comes to cutting your memory foam mattress, there are several steps you can follow.

Remove The Packaging And Unroll The Mattress

Remove the packaging from your memory foam mattress. 

If you own a mattress in a box in Canada, it'll come rolled up, so you'll need to unroll it. 

Then lay it out flat so you can cut it.  Be sure to lay it on a hard surface for safety purposes.

Place The Mattress On A Flat Surface

Now it's time to start cutting. Place your mattress on a flat surface and cut off the excess length.

Measure Your Mattress 

Measure the length of memory foam you need to cut off. You can use a tape for this or mark it with a pencil and ruler. Remember to measure from the edge to the middle on both sides.  This will ensure that your cuts are even.

Make Your Cut

Now that everything is in place, it's time to do the job! 

Use any of the cutting tools discussed above to cut along the lines marked by the tape until your mattress reaches the desired length. Make sure you have a good grip on the knife when making these cuts.

Trim off The Excess Bits

Once you've finished cutting to the desired length, it's time to trim the excess bits from the sides. 

Use a small paintbrush to brush away any loose bits of foam from around your mattress. You should also sweep away as much loose foam as possible.

Replace The Mattress Cover

Now that your memory foam mattress is cut down, you can replace the cover. It's finally time to enjoy the comfort of your new mattress.

How to Cut A Memory Foam Mattress Horizontally

You may need to cut a new mattress horizontally at some point. Perhaps you are moving and need to fit the mattress through a tight space, or maybe you just want to make your mattress thinner. 

Whatever the reason, it is important to know how to do it properly.

To avoid damaging your mattress, you must take the proper precautions.

There are specific tools to ensure cutting a mattress horizontally. A large horizontal saw is essential if you intend to cut memory foam. If possible, look for an electric model which includes a clamping mechanism. 

It is usually much easier to cut the foam using an electric knife because of its flexibility and ability to work around sharp corners. If you purchase a non-electric knife, consider having it sharpened to increase the accuracy of your cuts.

Begin by placing the memory foam mattress in the correct position. It is good to spread the foam out to make the edges more stable. This helps prevent the foam from shifting during the operation.

You can also use a hot wire to cut your mattress horizontally. Be careful not to move the wires at all, as they can easily slip and cause further damage to the foam. The most effective way to use a hot wire is to insert the point into one end then press down against it. 

Avoid pushing too hard onto the mattress at first since you could push the wire farther into the foam and cause damage. After ensuring no movement on the foam, slowly begin pressing down against it. 

IMPORTANT: Your mattress is an expensive piece of furniture. It is not recommended to cut your mattress horizontally unless absolutely necessary.
