Description

When a cushion is wider at one end than the other, a standard rectangular cover will twist, skew, and pull at the seams. Custom trapezoidal cushion covers are patterned with independent front and back widths plus depth and thickness, so the finished cover naturally follows the taper, staying centered and aligned on your furniture.

You’ll measure the narrow edge, wide edge, depth from front to back, and overall thickness. If the corners are angled or slightly rounded, include that information and share photos or a quick drawing. This is especially helpful for custom-made cushion covers in RVs, boats, bay windows, or tight corner seating.

Why choose custom trapezium cushion covers?

  • True tapered fit: Eliminates the twisting and bunching that happens when forcing a rectangular cover onto a trapezoid cushion.

  • Space-optimized: Perfect for angled walls, narrowing benches, or any layout where one edge must be shorter.

  • Ready for real-world use: Performance fabrics and YKK zippers are built for frequent use and simple cleaning.

Fabrics information

Trapezium cushions appear in built-ins, RV seating, boats, dining nooks, and tight spaces where furniture must narrow at one end. Waterproof Horizon handles outdoor, marine, and high-moisture situations, while breathable Canvas delivers comfort and airflow in protected or interior areas. Both are excellent for custom cushion covers that must follow a precise taper without twisting or wrinkling.

Feature highlights

 

  • Designed for tapered cushions where one side is longer or wider than the other (trapezoid shapes).
  • Built to a specific front width, back width, seat depth, and thickness.
  • Available in Sunbrella Horizon (waterproof vinyl) or Sunbrella Canvas (breathable acrylic).
  • UV, fade, mold, and mildew-resistant performance fabrics suitable for indoor–outdoor spaces.
  • Durable YKK zippers for easy removal and consistent performance.
  • 5-year fabric warranty, plus Horizon’s 3-year warranty against bacterial pinking.

Frequently Asked Questions

Measure the width of the narrow side, the width of the wide side, the depth from front to back, and the cushion thickness. Note whether the side edges are straight or angled, and include a quick sketch or photos to show which side is which.
If the difference between the two sides is noticeable when the cushion is in place, a trapezium cover will give a cleaner, more centered look. Even small tapers are easier to manage with a pattern that matches your actual dimensions.
If the cushion is in a space that sees moisture, spills, or open windows, Horizon’s waterproof protection is often the best choice. For interior, climate-controlled seating where comfort is key, Canvas typically feels better while still resisting stains and fading.
Because the cover is patterned with different front and back widths, it is designed to sit in one orientation and stay centered. Using the correct measurements and quality foam helps maintain that alignment over time.
Yes. Using the same fabric family and color for your trapezium, rectangle, L-shape, and curved cushion covers creates a cohesive, tailored look across all your seating.
