We need the measurements of the cushion cover that you are looking to fill. Turn your cushion cover inside out and then measure the dimensions as shown in the diagrams below. It is extremely important that we get these measurements correctly and accurately as we will use them to produce your order. Once we have the sizes from you, we will be able to make the cushion filling. We will very slightly oversize the cushion filling to make sure that you get the full and plump fill your cushion covers will need. Our fillings will never be smaller than the empty cushion cover measurements you give you us.

Made to Measure Triangle Foam Cushions

Our triangle foam cushions are designed for angled seating, campervan interiors and bespoke furniture layouts where standard square cushions cannot provide the correct fit. Their shaped triangular profile follows specialist seating layouts precisely while delivering firm support and structured everyday comfort.

Perfect for compact seating areas and custom-built furniture projects, every cushion is handmade in the UK to your exact supplied dimensions.

What Is a Triangle Foam Cushion?

A triangle foam cushion is a shaped seating cushion designed for angled furniture layouts and specialist seating applications. These cushions are commonly used where sloped seating areas, corner spaces or compact layouts require a more precise triangular seating shape.

The triangular profile allows the cushion to fit neatly within angled seating layouts while maintaining a clean and professionally tailored appearance.

Firm Foam Support for Structured Seating

Using premium furniture-grade foam, these cushions provide dependable support and long-lasting comfort while maintaining their structure through regular use.

Foam filling helps provide:

  • Firm seating support
  • Improved posture comfort
  • Long-lasting shape retention
  • Structured seating feel
  • Consistent support performance

This makes triangle foam cushions especially suitable for compact seating layouts and high-use furniture applications.

Ideal for Campervans, Benches and Angled Seating

Triangle foam cushions are regularly selected for:

  • Campervan seating
  • Boat seating
  • Angled bench seating
  • Corner furniture layouts
  • Bespoke seating projects
  • Compact seating areas
  • Custom-built interiors

Their shaped triangular design helps create a seamless and professionally fitted finish throughout specialist seating layouts.

Restore Comfort to Worn Seating Areas

Many customers choose replacement triangle foam cushions when their existing seating becomes flat, uneven or uncomfortable.

Replacing the cushion interior is often considerably more affordable than replacing the full seating layout, particularly when the furniture frame and upholstery remain in good condition.

New foam cushions can help restore:

  • Firm support
  • Shape definition
  • Structured seating comfort
  • Seating height
  • Furniture appearance

Foam cushions are ideal for customers wanting supportive seating that maintains its structure and comfort over time.

Their durable construction makes them suitable for both residential and commercial seating environments.

A More Structured Alternative to Fibre Cushions

Customers often choose triangle foam cushions when they want firmer seating support and improved structure compared to softer fibre interiors.

Foam filling is ideal for angled seating layouts where posture support, durability and shape retention are prioritised.

If you prefer a softer and more relaxed seating feel, you may also wish to explore our fibre cushions, seat cushions and bench cushions.

Every order is handmade specifically to your supplied dimensions and delivered ready to refresh your seating and furniture layouts.
