Description
Triangle cushions cut to your exact angles — for corner benches, window seats that meet a wall, boat berths, wedge-shaped nooks and custom furniture where a rectangle simply won't fit. Enter your base, height and thickness and we hand-cut each triangular piece so every edge lines up with your space.
Choose firm high-density foam for supportive daily seating or lighter fiberfill for decorative and occasional use, then pick from our indoor and outdoor fabrics. Add piping to sharpen the angled edges and ties to hold the cushion in place. Measure the two straight sides and the longest edge, note any right angle, and your exact price appears on screen instantly — no quote, no waiting. Backed by our 14-day perfect-fit guarantee.
How to measure
- Measure and note the base, height and thickness you need.
- Enter each size in the Measurements step of the configurator, then choose the fill and the fabric.
- Check every value under Review & Confirm before you add the cushion to your cart.
Sizes can be entered in inches or centimetres on each product page.

Do’s and don’ts · 12 tips
Do
- Brush or vacuum before any wet cleaning.
- Blot spills immediately with a clean lint-free cloth.
- Test any new cleaner on a hidden seam first.
- Clean the whole panel, seam to seam, to avoid water rings.
- Dry everything completely before storage or reuse.
- Plump, rotate and swap cushion positions weekly.
Don't
- Never machine-dry outdoor or velvet covers.
- No pressure washers — they break down fabric coatings.
- Avoid rubbing in circles — it spreads and sets stains.
- Skip fabric softeners and scented detergents.
- Never leave foam in direct sun for more than a few hours.
- Don't store cushions damp or sealed in plastic.
