Custom Foam Cut to Size in Perth: How to Measure, Choose & Order

Need new cushions, a caravan mattress, or a custom foam insert? Choosing the right foam cut to size in Perth can make all the difference in comfort, durability, and cost. At Foam Supplies WA, we make it simple to order foam tailored to your project — but before you buy, it pays to know how to measure, what foam type you need, and how to order the right fit.

Why Getting Size & Foam Type Right Matters

• A snug fit avoids sagging, wrinkled covers, and uneven wear

• The right density and thickness make cushions and mattresses more comfortable and supportive

• Outdoor and marine projects require UV-resistant, water-resistant foams to last in Perth’s climate

• Ordering custom cut foam means less waste and better value

Tools You’ll Need

• Tape measure (steel or rigid for accuracy)

• Flat surface to measure on

• Existing cover or foam (if replacing)

• Pen, paper, or phone to record sizes

• Optional: cardboard template for curves or odd shapes

How to Measure Custom Foam

1. Length & Width

Measure the inside dimensions of your cover or frame, seam to seam, at the widest points.

2. Thickness

Measure the depth from base to top. For seating and mattresses, 75–100mm is common, but firmness may require more or less.

3. Special Shapes

For rounded, wedge, or T-shaped cushions, trace a cardboard template to ensure accuracy.

4. Allow for Fit

If foam is going inside a cover, order a few millimetres larger so it fills neatly.

Choosing the Right Foam for Your Project

Real Examples

• Patio Cushions in Rockingham: A 1100mm × 500mm seat base, 75mm thick, cut in outdoor UV-resistant foam.

Tips to Avoid Mistakes

• Measure twice, order once

• Always measure the cover or frame, not just old foam (which may have shrunk)

• If unsure between two thicknesses, go slightly firmer — foam softens over time

• Keep old foam until the new one arrives for comparison
