Foam Guide

What Foam Do I Need?

Not sure which grade to pick? Our simple guide helps you choose the right foam density and firmness for your project.

Foam Grades Explained

Medium Density (36kg/m³)

Firmness: Medium

Best for: Back cushions, occasional seating, headboards

A softer foam ideal for areas where you lean against rather than sit directly. Perfect for back cushions and decorative seating where firm support isn't critical.

Firm High Density (40kg/m³)

MOST POPULAR

Firmness: Firm

Best for: Seat cushions, sofas, dining chairs, window seats

Our most popular grade. Provides excellent support for everyday seating. Ideal for sofa seat cushions, dining chairs, and bench seats that get regular daily use.

Extra Firm (50kg/m³)

Firmness: Extra Firm

Best for: Heavy-duty seating, commercial, medical

The firmest option for areas with heavy or constant use. Ideal for commercial seating, medical cushions, and seats where maximum support is needed.

Memory Foam (50kg/m³)

Firmness: Medium (moulding)

Best for: Mattress toppers, wheelchair cushions, comfort upgrades

Conforms to body shape for pressure relief and comfort. Excellent as a mattress topper or combined with a firm foam base for seats where comfort is the priority.

Reflex Foam (40kg/m³)

Firmness: Supportive

Best for: Mattresses, sofa beds, bases

A resilient foam that bounces back quickly. Often used as a mattress core or combined with memory foam on top. Good balance of support and comfort.

About Extras

Dacron Wrap

A polyester wadding wrapped around the foam. It softens sharp edges, adds loft and roundness, and gives cushions a plump, inviting look. Highly recommended for sofa cushions.

Stockinette

A stretchable fabric sleeve pulled over the foam. It lets cushion covers slide on smoothly, protects the foam from friction, and gives a neater, more professional finish.
