Trapezium Replacement Cushion Covers – Made to Measure UK

Trapezium Cushion Covers – Covers Only or Foam Filled

We manufacture trapezium replacement cushion covers made to measure for campervans, caravans, boats and domestic seating.

Designed for angled and tapered layouts, trapezium cushions require accuracy — which is why all our covers are produced to your exact measurements.

You can order:

• Covers only – ideal if your existing foam is still in good condition
• Foam filled cushions – complete cushions with new foam inserts

Every order is made to size, ensuring a precise fit and a clean, professional finish.

Made to Measure Trapezium Cushion Covers for Angled Seating

Trapezium cushions are commonly used where straight edges won’t work, including:

• Campervan side seating and rock and roll bed sections
• Caravan front lounges and corner seating
• Boat and marine seating layouts
• Bay windows and shaped domestic furniture

These tapered shapes are rarely standard, which makes made to measure trapezium cushion covers the only reliable way to achieve a proper fit.

Three Core Cushion Cover Styles

We offer three main styles for your trapezium cushion covers, depending on use and finish:

Wrap Style Cushion Covers

A simple, flexible design where the fabric wraps around the cushion. Suitable for backrests and lighter-use areas.

Box Pleat Cushion Covers

A more structured design with defined edges, ideal for seating where a tailored appearance is required.

Box Cushion Covers

A full box construction with straight sides, designed for seat bases and high-use areas where support and durability matter.

Each style can be customised with:

• Piping (or no piping)
• Buttoned finishes
• Knee rolls and shaped edges

Covers Made to Fit Tapered and Angled Shapes

Trapezium cushions require more than just length, width and thickness — the angles must be correct.

Our replacement trapezium cushion covers are made to your exact dimensions, ensuring:

• Accurate tapered edges
• Clean lines and tight corners
• No excess fabric or poor alignment

If you can measure it, we can make it.

Covers Only or Foam Filled – Choosing the Right Option

If your existing foam is still supportive, ordering covers only is the most cost-effective option.

If your cushions feel uneven, worn or uncomfortable, our foam filled cushions allow you to fully upgrade both comfort and appearance.

We also supply foam cut to size for trapezium cushion inserts if required.

Important – Fabric Is Sold Separately

Please note the following before placing your order:

All prices shown include VAT but do not include fabric.

Fabric must be purchased separately.

This allows you to select the exact material, colour and finish to suit your project.

Made to Measure Means a Proper Fit
