Foam is a versatile material used in a wide range of applications, from upholstery and crafting to insulation and packaging. Cutting foam accurately and cleanly is essential to achieve professional-looking results in your projects.
For over 20 years, FoamOrder has been providing foam to shops, workrooms and DIYers, serving a wide range of projects. In this guide, we’ll explore the techniques and tools needed to cut different types of foam effectively, empowering you to confidently achieve professional results.
To cut foam effectively, you’ll need the right tools. Many tools you might need can be found on our partner’s website, Upholster.com. Here’s a list of essential tools you may need:
A sharp utility or foam cutting tool is a must-have for cutting flat and curved surfaces on all types of foam.
For thicker foam or larger projects, a serrated electric carving knife provides a precise and even cut. It’s especially useful when cutting dense foam, such as memory foam mattresses or upholstery foam.
A hot wire cutter is specifically designed for foam cutting. It operates by melting through the foam cleanly, leaving smooth edges. This tool is excellent for intricate cuts and shaping.
Good-quality scissors with sharp blades are suitable for cutting thin foam or neoprene sheets. They come in handy for crafting projects that require detailed cuts.
Ideal for precision cutting, a rotary cutter with a sharp circular blade is excellent for intricate foam designs. It’s often used in quilting and crafting but can also be useful for foam projects.

Cutting upholstery foam can vary depending on the type of foam and your project’s complexity. Here are tips on cutting upholstery foam effectively:
EVA is a type of closed cell foam that is a popular choice for cosplay and craft projects due to its versatility and ease of cutting. Here’s how to cut EVA and other closed-cell foams like volara, cross-poly, and flotex foam:
To achieve smooth and sealed edges on EVA foam, you can use a heat source like a heat gun or a lighter. Gently pass the heat source over the foam’s edges, which will cause them to melt and seal.
Regardless of the type of foam you’re working with, it’s essential to prioritize safety. At FoamOrder, we provide top-quality foam materials and prioritize safety by offering guidance on best practices and material safety data sheets. To further ensure your safety, follow these steps:
Work in a well-ventilated area or use a mask when cutting foam, especially polystyrene. Proper ventilation helps reduce the inhalation of any potentially harmful particles.
Wear safety goggles or glasses to protect your eyes from foam particles and debris. Foam cutting can produce small particles that may cause irritation or injury if they come into contact with your eyes.
Ensure your cutting tools are sharp, as dull blades can lead to accidents and rough cuts. Regularly replace blades to maintain clean and precise cuts. Be sure that you are always aware of where electrical cords are and will be during your cutting to ensure you don’t cut the cord. A best practice is to simulate your full cutting plan/movements to ensure the cord won’t get in the way.
Pay close attention to your fingers while cutting, and be cautious not to cut yourself. Keep your hands clear of the path of the cutting tool to prevent accidents.
Properly dispose of any foam waste according to local recycling or disposal guidelines. Some types of foam can be recycled, while others may need to be disposed of in a specific manner.
Cutting foam is fundamental for diverse DIY ventures, spanning upholstery, crafting, insulation and packaging. At FoamOrder, we recognize the importance of selecting the ideal foam type, using the right tools and adhering to stringent safety measures to attain immaculate, precision cuts for your unique projects. Whether you’re tackling upholstery, EVA, polystyrene or closed-cell foam, these tried-and-true techniques are your gateway to professional-grade outcomes. Explore various methods to tailor your approach to the specific demands of your project, and unlock the boundless creative potential that foam offers in your DIY pursuits.
