Replacing a Mattress? How to Choose the Right Foam (and Get It Cut to Size)

29 May 2025 by

If your mattress is sagging, uncomfortable, or simply past its prime, replacing the foam can be a smart and affordable option. Whether you're updating a bed, caravan, campervan, or daybed, choosing the right foam is key to a good night’s sleep.

Why Replace with Foam?

Foam mattresses offer excellent support, durability, and comfort. They’re also lightweight, making them ideal for caravans or adjustable bases. Best of all, you can customise them to your preferred thickness and firmness.

Understanding Foam Density & Firmness

  • Density refers to how much material is in the foam (measured in kg/mΒ³). Higher density = longer-lasting support.
  • Firmness (measured in Newtons) determines how the mattress feels. You can choose soft, medium, or firm based on your sleeping preference.

For help understanding foam grades, see our foam buying guide.

Memory Foam vs. High-Density Foam

  • Memory foam contours to your body and offers pressure relief. Ideal for mattress toppers.
  • High-density foam provides firmer support and is often used as the core in mattress builds.

Standard Sizes or Custom Shapes

Whether you need a Single, Queen, or something uniquely shaped for a caravan or daybed, we’ve got you covered.
