When your cushion curves into a corner, finding a cover that actually fits is like trying to find a needle in a haystack. Whether it’s a quarter-circle bench in your camper, a bowed seating area on a boat, or a curved corner nook at home, standard covers simply can’t keep up.
That’s why we offer made-to-measure Curved Quarter Cushion Covers, crafted to follow the arc, hug the edge, and fit every inch of your seat — properly.
So if your cushion’s shaped like a quarter of a pie, you’ve just found the perfect slice of the solution.
Curved quarter cushions bring comfort and visual flair — but they also bring measurement nightmares. Get it even slightly wrong, and the result is baggy seams, pulled edges, or a wonky sit.
That’s why every cover we make is cut to your exact radius and depth — ensuring that it not only fits like a glove but follows the curve naturally, without distortion.
Compared to off-the-shelf attempts, our covers don’t force a round peg into a square hole — they’re shaped from the start to fit curved corners properly.
The shape’s sorted — now it’s time to style it. Whether your space is modern, classic, rustic or nautical, we’ve got a finish to suit.
Choose from:
Wrap Style – simple, minimal, and sleek
Box Style – adds sharp edges and a more defined structure
Box with Piping – for that classic upholstered look
Box Pleat Style – traditional, detailed, and full of texture
All styles are made to order by skilled hands right here in the UK, using time-tested techniques and quality materials.
Shape and style aside, fabric makes the biggest difference. Whether your cushion is indoors, outdoors, or constantly on the move, we’ve got fabric choices to suit every scenario:
For boats, caravans, and exterior benches, our UV-stable, water-resistant fabrics are a solid, durable choice
For indoor cushions, we offer velvets, cottons, easy-clean blends, and woven textures — all handpicked for comfort and longevity
Want something with variety? No problem. We can make your cover reversible with a different fabric on each side — ideal for mixing up your space without changing the cushion.
Not sure which way to go? Request free fabric samples and see for yourself before you decide.
Sometimes the problem isn’t the cover — it’s the foam underneath. If your cushion core’s lost its bounce, we’ll supply curved foam cut to match your quarter shape exactly.
Select from:
High-density foam – firm, supportive, long-lasting
Reflex foam – soft and springy, great for lounging and informal setups
We can also wrap your foam in Dacron or Stockinette for a smoother fit and a plumper look inside the cover.
Awkward shapes need practical solutions — which is why we offer a few extras that make all the difference in daily use:
Pick your zip location to suit where the cushion sits
Add a non-slip base, especially useful for moving vehicles or smooth benching
Include Velcro tabs, ties or fixings to keep everything secure
And yes — all our covers are fully removable and washable, so cleaning is quick and painless.
Why bin a perfectly good curved cushion just because the cover’s looking a bit tired? Especially when that shape’s near impossible to replace?
Instead, go custom — and give your existing foam a second life with a new, properly made cover. It’s the cost-effective, sustainable, no-nonsense solution.
We’ve made the process simple and accurate. Just follow these easy steps:
Choose your units — mm, cm or inches
Enter your cushion’s radius and depth, and note any specific details (e.g. flat edge measurements)
Select your cover style, fabric, and extras
Add any special notes — zip placement, fabric preferences, etc.
Click “Add to Cart” — and we’ll take care of the rest
