Custom Circle Cushion Covers – Made to Fit Every Curve, Built to Go the Distance

Circle Cushion Cover look great — until you try finding a cover that fits them properly. Whether it’s a floor cushion, a round window seat, a central bench in a boat, or a statement cushion in your lounge, one thing’s for sure: standard square covers just won’t cut it.

That’s why we offer made-to-measure Circle Cushion Covers, cut with precision and finished with care. No bunched seams. No makeshift stretching. Just a smooth, snug fit that’s crafted for comfort — and built to last.

So if you’re tired of trying to cram your circular cushion into something made for corners, this is the solution that finally makes sense.


Perfectly Tailored – Because Circles Aren’t Squares

Circular cushions are unique. They don’t have corners, but they do have challenges. A few millimetres off and suddenly your cover is puckered, loose, or just plain wonky.

That’s why we build to your exact measurements, ensuring a clean, symmetrical fit that follows the curve perfectly. We’ll cut your cover to match the diameter and depth of your cushion — no pulling, twisting, or guesswork.

As a result, your cover won’t just fit better — it’ll look better, sit better, and last longer.


Style Options to Suit Every Setting

Just like any other shape, round cushions deserve a proper finish. That’s why we offer four distinct cover styles — each one tailored to suit different aesthetics:

  • Box Style – adds height and structure around the edges
  • Box with Piping – timeless, with a crisp tailored outline

  • Each cover is cut, sewn, and finished by hand in our UK workshop — made to order, and made to last.


Fabrics That Work in Every Room — Or on the Move

Once you’ve got the shape and style sorted, choosing the right fabric brings it all together. Whether your round cushion lives inside or out, on land or at sea, we’ve got you covered.

  • For outdoor or marine cushions, choose our UV-resistant, water-repellent fabrics — tough enough to handle weather and wear

  • For indoor seating, pick from plush velvets, breathable cottons, or woven textures in a wide range of colourways

Even better, we offer reversible options — choose a different fabric for each side so you can flip your cushion whenever you want a change of look.

Still undecided? No stress — request your free fabric samples, and we’ll send them right out.


Need Foam? We’ll Cut the Perfect Circle

If your cushion core has seen better days, we’ve got your back. We can supply circular foam inserts cut to your diameter and thickness — no more chopping corners to make it fit.

Choose from:

  • High-density foam – firm and supportive, ideal for upright or decorative use

  • Reflex foam – soft and cushioned, great for lounging or floor use

We also offer Dacron and Stockinette wrapping for added comfort, easier fitting, and a more polished finish.


Finishing Touches That Make All the Difference

To make sure your cushion stays in place and functions perfectly, we’ve added a few smart extras to choose from:

  • Pick your zip location to suit how you’ll use and access the cushion

  • Add a non-slip base, especially useful for smooth floors or moving vehicles

  • Include Velcro tabs, ties, or fastenings to secure it in position

And of course, every one of our covers is fully removable and washable, making it easy to keep clean.


A Smarter Way to Refresh Your Cushion

Let’s be honest — throwing out a perfectly good cushion just because the cover’s worn out is wasteful. Especially with circular cushions, which are notoriously tricky to replace.

Instead of starting from scratch, upgrade the part that matters most — the cover. It’s cost-effective, sustainable, and it’ll make your whole space look better instantly.


How to Order Your Circle Cushion Cover – No Fuss, Just Fit

We’ve made ordering easy — even for unusual shapes. Here’s how it works:

  1. Select your unit of measurement — mm, cm or inches

  2. Enter your cushion’s diameter and thickness

  3. Choose your cover style and fabric

  4. Add any extra notes — like zip placement or different fabrics for each side

  5. Click “Add to Cart”, and we’ll take it from there

Need help measuring? Just get in touch — we’re happy to guide you through it.
