Description

L-Shaped Foam Core Fibre Seat Cushion – Made to Fit, Built to Last

Designed for corner seating, built-in benches, or wraparound window seats, our L-Shaped Foam Core Fibre Seat Cushions offer a custom fit and lasting comfort. With a solid foam centre and soft fibre wrap, these cushions deliver the structure you need with the comfort you expect — no sagging, no fuss.

Each one is made to your exact cover size, with a built-in return section to fit snugly around corners or into L-shaped frames.

🧵 How They’re Made

Every cushion is constructed with a foam core shaped to your specific layout and then wrapped in soft polyester fibre for that full, plush finish. The L-shape is cut as one piece to ensure a clean fit without shifting or gapping.

You can choose from three comfort levels:

  • Soft – relaxed and sink-in feel, ideal for lighter use

  • Medium – our most popular balance of comfort and support

  • Firm – for a more structured feel or high-use seating

This combination of foam and fibre gives you support that doesn’t sag, with a layer of softness to keep it comfortable.

📏 How to Measure – 5 Key Dimensions

To ensure a perfect fit, measure your empty cushion cover and send us these five measurements:

  1. Section A – Maximum width of the cover

  2. Section B – Front to back measurement

  3. Section C – Cushion thickness/border

  4. Section D – Front to back of the return leg

  5. Section E – Width along the back edge of the cover

If you’re unsure, send us a paper template or the cover itself — we’ll do the rest.
