How To Cut A Memory Foam Mattress

How To Cut A Memory Foam Mattress At Home


Step #1. Preparation

Before anything else, please check with your manufacturer before cutting your memory foam mattress if you don’t want to void your warranty accidentally. Once you have the signal, you can prepare a sharp knife, marker, and tape measure. You may need to sharpen your knife to ensure that you’ll cut the memory foam neatly. 

There are different mattress sizes, and you can use their standard dimensions as a guide for cutting. You also want to consider where you’ll use the memory foam and how much foot and headspace you have for it. Furthermore, memory foam mattresses vary in thickness, and some may use other materials in their layers. 

Some sizes for your mattress include twin, twin XL, king, California king, full, and queen. You must know their dimensions so you can mark your bed accurately. Remove the cover and trace a cardboard template according to the size you’ll cut. 


Step #2. Cutting

What if your mattress has a cover? You can cut it with cloth scissors along the short edge of the bed. You don’t need to fully cut the cover as long as you can take out the mattress comfortably. 

This way, you can reuse the cover later on by resizing it. Place your bare mattress on a flat and steady surface and position the knife so that it’s parallel to the bed’s height. The emphasis is on not applying pressure when slicing the mattress to avoid differences in the measurement and shape. 

For thicker memory foams, your knife might not cut all the way through. To ensure a neat slice, make a shallow cut first and then a deeper cut the second. Some mattresses may also have varying densities per layer, and if yours is too soft, put cardboard on one side to avoid compressing it as you slice. 


Is It Ok To Cut A Memory Foam Mattress?

You can cut a memory foam mattress as long as you’re mindful of the warranty and care throughout the process. Furthermore, it’s a great way to utilize some beds that you no longer use or have to make into a different size or shape. Your memory foam will be useful for other areas, and you can customize it for frames.  


Types of memory foam densities

To make cutting easier, it’s best to familiarize yourself with different foam densities. For example, soft memory foam is best as padding, while a medium-density foam is better in terms of lifespan. The latter is also useful for babies because it’s not as conforming as high-density memory foam. 

Memory foams labeled high and very high densities will have the best lifespan among the other types. They are perfect for beds, sofas, and even vans because they won’t flatten or sag quickly. Please note the characteristics to expect with every memory foam density as a guide when cutting your mattress. 


Materials typically mixed with memory foam

You should also know that some memory foam mattresses have other materials besides memory foam. They can affect the cutting, and they include gel and fiberglass. Since memory foam tends to retain heat, manufacturers add gel to help keep it cool. 

On the other hand, some mattresses have fiberglass as a fire retardant. Be extra careful with this material, significantly when cutting. Always wear protective gloves and glasses to keep debris away. 


What Is The Best Tool To Cut Memory Foam?

The best tool you can use to cut a memory foam mattress is a sharp knife. Some prefer a serrated type because it’s more comfortable for sawing. If you’re worried about the resulting serrated edge, do note that you’ll cover the mattress anyway. 

Some other tools that might work are electric knives and shears as long as they can handle the foam. But if you’re cutting a memory foam mattress horizontally, the hot wire might be the most convenient. It will also work if you have a particular shape in mind or if you’re using high-density foam.

You can also use an electric saw if you have no space to work with a hot wire. Follow the guidelines above, and then trim the excess if needed. 



Do you need to resize your bed? Then, you must understand how to cut a memory foam mattress correctly to avoid damaging the material. It’s also crucial that you check your item’s warranty beforehand. 

You can follow the standard bed sizes’ dimensions and cut a cardboard template for tracing on the mattress. Then, use a sharp knife and be mindful of the materials and foam density. As long as you don’t apply pressure on the foam, and you can be confident that you’ll cut it neatly.

What Is A Short Queen Mattress? 3 Best Reasons To Buy This!

What is a short queen mattress? It’s mainly known for three things: convenience, comfort, and hypoallergenic; these traits make this mattress one of the best options out there.

Yes, I know for a fact that you are familiar with queen mattresses.

But do you have any idea about a short queen mattress?

You cannot commonly see this among mattress stores not unless you are specifically looking for this.

Some people opt to get this for particular purposes.

Now to answer the question lingering in your mind, a short queen mattress, as per its name, is also a queen-sized mattress.

It’s only that this one is slightly shorter than a standard queen mattress.

If we go into the specific measurements, the standard queen measures 60 inches in width and 80 inches in height.

Whereas a short queen is also 60 inches wide but only measures 75 inches tall.

So yes, we are only talking about the five-inch difference here.

Maybe the difference only seems irrelevant to you and would never matter for some – depending on their height.

But for people that make a lot of movement in bed or what we call active sleepers, or even for tall sleepers, such a slight difference could mean great.


Reasons Why People Like Short Queen Mattress

The primary reason people want to get a short queen mattress is to use it in an RV.

There are a lot of reasons why RV mattresses are made shorter. Size and weight are the major ones.

As we all know, there is only a maximum of weight that a vehicle can pull when towing an RV.

Everything inside it contributes to the total weight, and that includes the mattress.

For that particular reason, RV manufacturers intentionally cut the weight wherever possible.

Just imagine a memory foam-type queen mattress that can weigh up to a hundred pounds. That’s quite heavy.

And since mattresses belong to those that are pretty heavy, they are included in those cut-offs.

Talking about cutting corners, the RVs are made tight and narrow with all their space efficiently utilized to maximize their capacity.

You can use the five-inch space provided by the mattress being cut off to expand the bathroom or the kitchen.

So even if the short queen looks like something that is a tight fit, at times, this type of mattress is just what you need.


Is It Comfortable To Sleep In A Short Queen Mattress?

Of course! Sleeping on a short queen mattress is completely as comfortable as the standard queen mattress.

That is especially true if you know what to buy.

Some RVs come with a subpar mattress that cannot offer you a good night’s sleep, but you may choose to switch it into a short queen mattress.

You might want those memory foam that NASA invents for astronauts.

They are intentionally made to minimize pain caused by strenuous travel.

So, if you wonder how, the memory foam eases the pressure points by cradling your body.

It conforms to your body, so the mattress equally cushioned, starting from your hips towards your shoulder and neck.

However, too snug-fitting memory foam can sometimes lead to overheating.

It happens when the mattress overly absorbs the shape of your body.

That is precisely the reason why people opt to get memory foam.

The gel beads integrated into the memory foam can diffuse heat, thereby taking away the sweaty feeling and providing you a good night’s sleep.
