How to Cut a Memory Foam Mattresses and Mattress Toppers?

This cutting is similar to cutting open any other type of mattress. You can use special tools or use an electric knife. The following are the steps you need to take when cutting:

Make sure you have a ruler, a marker pen, and a sharp knife on hand

Most importantly, make sure that you have your mattress and bedsheet in front of you.

The size will determine how many times you will need to cut it. Before cutting, do a quick measurement to ensure that each section will be at least 4 inches apart from one another! Check if the place where you will be placing the mattress has enough room for it!

Determine the size and dimensions of the mattress that you desire.

For example, if you want to create three mattress pieces measuring 4″ x 6″ each, you need to find the center of your mattress first.

To do this, use a marker pen and draw lines connecting one corner of your mattress with the other until it reaches its widest point! You can also lay down on your bed and imagine a line connecting one corner of the mattress to another.

Draw a diagonal line from one corner to the other, measuring 4″ on each side. Make sure that it is from the widest point of your mattress! You can also print a pattern online and trace around it until you get a perfect fit!

Remove the mattress cover.

Place the ruler on the widest point of your mattress and make a mark with your marker pen! Do this all along the width of your mattress.

Take off the cover and place the ruler on any one corner horizontally. Make a line at 2″ to create extra space for cutting.

Measure and mark where you want to cut.

Make a mark every 2″. This will allow for a comfortable fit to your bed frame or any other bed where you plan on placing it!

Measure and mark where you want to cut from both corners until you get to the center of your mattress. Make sure that there is at least 4″ between each section to have a comfortable and easy movement.

Remove the memory foam or mattress topper from its packaging and carefully on a flat surface without compressing it.

Carefully cut along the line using a very sharp knife! Do not press on the memory foam while cutting it since this will make the mattress lumpy.

Trim off the excess and replace the mattress cover (re)fit.

Remove any excess memory foam and put back the mattress cover.

Make sure that you have made an even cut before fitting the new pieces to your bed frame or another surface!

Use a ruler to measure if each piece is 4″ apart from one another and arrange them accordingly on your bed.

Measure and mark where you want to cut from both corners until you get to the center of your mattress. Make sure that there is at least 4″ between each section to have a comfortable and easy movement.

Cut your memory foam mattress with a large, horizontal saw

Use a saw that can cut through the entire length of your mattress. If you lay down on your bed and it is wider than 5 feet, you will need to use a larger saw or have it extended sideways!

If you do not have any tools at home, consider going to a hardware store to ask for help from an expert who can cut it for you.

Measure and mark where you want to cut with a marker pen or sharp knife. Make sure that the pieces are equally spaced!

Place your memory foam on flat ground so that it will not roll during cutting! Lay underneath it so that you can see the areas marked with your marker pen.

Cut your mattress by slowly running the saw along your marked line!

Do not press on the memory foam while cutting it since this will make the mattress lumpy and difficult to clean. Do not try and speed up the process as well, or you might hurt yourself with the sharp blade of your saw!

After slowly cutting through one section, do the same to the other end of your mattress!

Once you are done, replace any leftover memory foam with its original packaging.

Use a hot wire to cut horizontally through your memory foam mattress

Choose a hot wire that has at least 1.5ft in length. Make sure that the wire is still flexible enough to cut through your mattress!

Plug your hot wire into an outlet and wait until it gets hot enough to melt the memory foam. This might take up to 30 seconds, depending on the strength of your wire’s electrical cord!

Kneel next to your memory foam and run the hot wire along any lines you might have drawn earlier with your marker pen or knife. Always make sure that it is hot enough before doing this because you do not want to cause a fire accident in your own home!

When done, reheat the wire and repeat for the other pieces that need to be cut!

Use an electric or manual miter saw to cut your memory foam mattress horizontally

Make sure that you have a piece of wood and some wooden planks under the area where you will be cutting. This is to prevent injuries from accidental falls as well as unnecessary damage to your floor!

Use a miter saw with a thin blade to cut through memory foam. Cut slowly and carefully so that you will not injure yourself or damage the thin blades of your saw.

After cutting, place any leftover pieces back into their original packaging boxes for future use.

Use a handsaw to cut your memory foam mattress in a straight line horizontally

You will need a handsaw, marker pen, and mattress cover for protection from flying sawdust!

Make sure that you have placed your memory foam on flat ground so that it will not roll around when sawing through the center of each section. Kneel next to your memory foam to make cutting easier!

Use your marker pen to make lines on the mattress where you want to cut. Mark one line at the very center of the mattress and then mark another line about 4 inches away from it. Since memory foam can be heavy, consider placing a piece of wood or two under your mattress for ease of cutting!

Run your handsaw along each line and make sure to saw through the entire length of your mattress.

After cutting, put any leftover pieces back into their original packaging boxes for future use.

Which Kind of Knife Should You Use to Cut Memory Foam Mattresses and Mattress Toppers?

There are many different ways to cutting, and while some will require special tools, others can be done using a knife.

Electric knife

An electric knife is ideal for cutting through your mattress. However, be careful not to cut yourself with the sharp edges of the blade and prevent any accidents from flying electrical sparks! Remember that electricity and water do not mix, so under no circumstances should you submerge your electric knife in water or run it while it is wet.

Manual knife

Manual knives such as the ever-popular Swiss Army Knife are also suitable for cutting, and they can be bought at most department stores or online shops like Amazon.com. However, avoid using a manual knife if you have arthritis due to its bulkiness and small size.

Carving knife 

Carving knives are also suitable for cutting through memory foam as long as you have a steady hand. They come in various shapes and sizes, but a carving knife with a serrated edge would be the most effective kind. Remember always to use a carving knife with a sharp blade, or else it will tear your mattress instead of cutting it! To make the cutting easier and faster you may use an electric carving knife. You can buy the electric carving knife from an online store like Amazon.

Craft (utility) knife

Craft knives or utility knives come in different shapes and sizes, but they are mainly used to sharpen or cut through thick pieces of paper. They are also suitable for cutting through soft materials such as foam so if you are on a budget, consider using a craft knife!

Extra-large scissors

Extra-large scissors are also suitable for cutting as long as you have a steady hand. They come in various shapes and sizes but try to find extra-long stainless steel scissors to make the blades very sharp. Remember always to open wider your scissors when cutting through thick materials!

Long serrated knife 

A long serrated knife is also good for cutting through due to its long and very sharp blades. They are usually sold in sets of three or four so if you need more than one, consider getting a set instead of buying them individually.

You’ll also need the following tools:

Scissors 

Scissors are also good for cutting, although it is recommended that you use large ones to avoid exerting too much pressure on the thin blades of your tool. You can buy scissors at most department stores or online shops like Amazon.com as well! Remember not to cut yourself with the sharp edges of the blades!

Marker pen 

A marker pen can also be used to make lines on your mattress that you want to cut. You can buy a pack of these pens from most office supply stores or discount superstores like Walmart and Target. Be mindful not to use permanent markers as they tend to bleed through the printed ink over time.

Handsaw

A handsaw can also be used to cut your mattress horizontally. However, it will take you more time to make cuts using this tool than using an electric or manual knife because of its bulkiness and slower cutting speed. Make sure that you place your memory foam on flat ground to not roll around while you are sawing.
