In this episode of The Campervan Podcast from Vansage.com, we answer the questions:

β€’ How do you cut a foam mattress?

β€’ What’s the best DIY way to cut a foam mattress?
β€’ What tools are need to cut foam?
β€’ How do you measure and cut foam?

And this applies to us because so many of us are creating custom campervan mattresses and cushions and bed sections. There are a lot of people asking this question online.

I've cut many pieces of foam myself for custom mattresses, bed sections and cushions. And it's not difficult. You can do it.

The best DIY approach to cutting a foam mattress is with a snap blade knife because the long sharp, thin blade will easily cut through the foam while allowing you to maintain a straight accurate cut.

Conversely, the best professional approach to cutting a foam mattress is with a foam cutting tool. Well, here's the thing with foam cutting tools: They cost several hundred dollars. The only advantages to using a foam cutting tool are that the cut will be slightly more straight or clean, and you can make the cut quickly.

So just real briefly, first of all, there's no reason to spend several hundred dollars on a foam cutting tool, unless you're going to get into the foam cutting business.

Don't spend the several hundred dollars for a tool that you'll use once every several years.

And as far as the speed and accuracy of the cuts go, here's what you're going to find:

When you use your snap blade knife, or some of the other tools I'm about to talk about here, you'll find that the cut will be a little bit imperfect.

You'll find that cut is somewhat imperfect, but you're going to cover it up with a mattress cover or a cushion cover. And no one will be the wiser.

The only people who know that my foam mattress cuts are a little bit jagged are me and you. So don't worry about that. It's not a big deal.

Again, the, the characteristics you're looking for in a cutting tool for foam are

β€’ The knife should be thin and long and very sharp.
β€’ So it is possible to use something other than a $2 snap blade knife, such as a chef's knife or a bread knife, but that knife has to be very, very sharp.

Snap blade knives: The nice thing about them is that they provide a long, straight, very sharp, almost razor-sharp edge. And of course you would want your snap blade knife to be new.

So you extend it all the way. If you're not familiar with snap blade knives, the way that they work is the reason that they are called snap blade knives is because you come out maybe it's an inch and you use this section of blade for a while until it's dull and then you snap it off and then can slide the knife out, another click and there's another section of blade there and it's new and sharp.

Well, when you're cutting foam, you just extend the snap blade knife all the way, and it comes out four or six inches or so.

When cutting foam, the length of the knife doesn't have to be the same as the thickness of your foam.

In other words, if you have a six inch piece of foam, six inch thick piece of foam, your knife, even if it's only three inches long, that's fine because no matter what, you'll need...
