How to Cut Memory Foam without Messing Up the Whole Process

April 12, 2017 by Maria

A high quality material used in the preparation of mattresses, best memory foam mattress toppers, and pillows, memory foam is essentially a polyurethane material that comprises of extra chemicals to enhance the viscosity and density. Memory foam tends to soften up when brought in close contact with the heat of the body. As a result it wraps around a warm body and gives it a greater degree of comfort. Upon removal of weight, it recovers to the original shape with the recovery process being a very quick one. This is one of the main reasons why memory foam is highly rated as a bedding material. However, when it comes to cutting or shaping memory foam it can be a very challenging process. With the right kind of equipment your disposal, you can overcome this challenge and go about cutting memory foam down to the required size.

Getting a clean edge is where you need to start

One of the most common issues faced when it comes to cutting memory foam is that it does not give you a clean edge. Being too aggressive with the right tool or starting out with the wrong tool altogether contributes towards the foam becoming rough and jagged along the edges. You should use the right tool with care to ensure a smooth and clean cut for your memory foam.

Carving knife

A carving knife comes with a serrated blade compared to those knives that have a smooth blade on them. There are tiny points on these serrated tips which are crucial to providing a straight, clean cut on the memory foam. With the help of gentle, short back and forth motions you can saw through the foam. It is important to ensure that the foam is not compressed.

Electric knife

An electric knife that is commonly available is another option. This too comes with a serrated blade similar to what you get in a carving knife. This is especially useful if you are cutting foam with the help of a template. The edge could be your guide as you slide the knife along the template to get the cut.

Utility knife

Craft knives or utility knives are surgically sharp and this makes them a good choice for cutting memory foam. The secret to using this equipment lies in making a number of easy passes over the memory foam material. Rather than sawing through the foam – something you would usually do while using a serrated blade – start by making a shallow cut-line before eventually deepening it till you finally manage to cut through the foam.

Heavy-duty scissors

You can make use of heavy-duty scissors for cutting thinner quality memory foam. Short chops are helpful in getting the right kind of cut especially when you are using the part of the blades that meet near the handles.

Additional tools to put to use

Apart from the usual knives and cutters, there are a number of other tools that you can use for cutting and shaping memory foam – marking pens, straightedge, Drywall square. All of these will help you in getting lines to give an accurate cut to your memory foam.

Drywall square

These are ideal for cutting long and straight pieces of foam. Take the necessary measurements and place the implement on the foam to square it up. Keep your knees on top so that the square remains steady. The side of the square will act as your guide with a utility knife running along the edge to give you a nice, clean cut.

An alternative to a conventional Drywall square would be a chunk of plywood with straight edges. You can use it in a manner similar to that of a Drywall square set.

Secure it down if necessary

Large pieces of memory foam have sufficient magnitude of friction that helps in keeping the object in place when you are cutting it. When dealing with smaller pieces, it is recommended that you have some heavy object placed along the edge or clamp it down if necessary. This will prevent your cut from going awry.

Some advice with the cutting

It is important that the memory foam is kept on a hard surface with the cutting edges hanging out of the surface. Hold it in place with one hand and have your cutter in the other to cut the foam along the required lines and surfaces.

Also if you are using an electric knife ensure that your fingers or the electrical cord is kept away from the cutting blade. You also need to be in a comfortable position before starting to use a cutter for cutting memory foam. Last but not the least you need to be cautious with everything while cutting the memory foam because all of it can prove to be very lethal.

Memory foam is a polyurethane material that has added chemicals to increase density and viscosity. A well-made memory foam mattress or memory foam mattress topper tends to soften when it gets in contact with body heat.

How to Cut and Size Your Personal Memory Foam Mattress

Memory foam has become very popular as a material to sleep on. It’s very comfortable, and a memory foam mattress or memory foam topper can transform your sleep experience.

However, memory foam mattresses and memory foam toppers usually only come in standard sizes, such as single, full, queen or king. If you have a particular bed or mattress that is not a standard size, that means you either have to get one custom-made or you will have to cut a standard size to fit.

A custom-made memory foam mattress or topper can be very expensive, and it can take a long time to get to you. An easier way, perhaps, is to cut your own mattress or topper to size, so that you don’t have to spend extra money to get a custom-sized memory foam topper or mattress.

There are several steps to cutting your memory foam mattress or topper to size.Here’s what you do:

Take the memory foam mattress or topper out of the package and let it breathe for about 48 hours. Lay it on a flat surface and let it expand to its full size. Usually, when memory foam products come to you, they are compressed somewhat at first. Laying your memory foam mattress or topper out and letting it expand it to its full size is going to give you a much more even cut.

Make sure you cut the memory foam bed or memory foam topper on a flat, firm surface. A mattress topper is going to be significantly easier to cut, of course, than a full mattress, but either can be done as long as you know what you’re doing.

The surface you cut your memory foam mattress or topper on should be completely flat and firm. For example, a tile floor is optimal for this, although you will want to put a piece of plywood or something similar underneath the mattress so as to protect the surface you’ll be cutting on.

Measure the bedor mattress you are going to place the memory foam on, and then measure the memory foam accordingly as well, with a tape measure.

If you’re going to be cutting a memory foam mattress, measure starting at the inside corners of the bed frame. For a mattress topper, measure the mattress itself that you’re going to place the foam topper on top of.

Then, mark the measurements you’ve made on the memory foam with a black marker. So, for example, if you are cutting an inch off of the memory foam all the way around, measure from the outside corner inward one inch in several spots, marking with a dot one inch in. Connect the dots when you’ve done all of your measuring, all the way around so that you have a straight line to cut on.

How to cut the memory foam

An electric carving knife will do a good job in cutting the memory foam, but make sure, again, that you put the mattress or topper on a surface that can take knife cuts. As stated previously, placing a piece of plywood underneath the memory foam mattress and on top of the surface you are going to cut on is a good idea, to protect your floor.
