Understanding Different Foam Shapes & Their Uses: A Guide for Every Project
When it comes to foam, one size—or shape—definitely doesn’t fit all. Whether you're reupholstering a beloved armchair, soundproofing a studio, or customizing cushions for a caravan or boat, choosing the right foam shape is just as important as selecting the right density.
At Foam Supplies WA, we offer foam cut to size and in a variety of custom shapes to suit every type of project across Perth and Western Australia. But what do all these shapes mean, and how do you know which one is best for you?
Let’s break it down.
🔲 1. Square and Rectangular Foam

🛏️ 3. Bolster Foam
Best for: Armrests, neck rolls, and caravan headboards.
Bolster-shaped foam is cylindrical and works wonders for adding support and style to chairs, lounges, or beds. It’s especially popular in caravans and campervans where space-saving foam shapes are essential.
