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

Round cushion covers look great — until you try finding one that actually fits properly. Whether it’s a floor circle cushion, a round window seat, a central bench in a boat, or a statement circular 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, designed specifically for round and circular cushions. 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 circle 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 round cushion cover is puckered, loose, or just plain wonky.

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

As a result, your round cushion 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, circle cushions deserve a proper finish. That’s why we offer a choice of professionally tailored styles, each suited to different looks and uses:

  • Box Style – adds height and structure around the edges

  • Box with Piping – timeless, with a crisp tailored outline

Each round cushion 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 circular cushion lives indoors or outdoors, at home or on the move, we’ve got fabrics to suit.

We also offer reversible circle cushion covers, allowing you to choose a different fabric for each side — perfect for refreshing the look whenever you like.

Still undecided? Request free fabric samples and choose with confidence.

Need Foam? We’ll Cut the Perfect Circle

If your cushion core has seen better days, we can supply circular foam inserts cut precisely to suit your circle cushion — no trimming corners or forcing square foam into a round cover.

Choose from:

  • High-density foam – firm and supportive

  • Reflex foam – softer and more relaxed, ideal for lounging or floor cushions

Dacron and Stockinette wrapping are also available to improve comfort, ease fitting, and give your round cushion cover a more polished finish.

Finishing Touches That Make All the Difference

To ensure your circle cushion cover performs as well as it looks, we offer a range of practical finishing options:

  • Choose your zip position

  • Add a non-slip base

  • Include Velcro tabs, ties, or fixings

All our round cushion covers are fully removable and washable, making them easy to live with long-term.

A Smarter Way to Refresh Your Cushion

Replacing a whole circular cushion just because the cover is worn out is wasteful — especially when round cushions can be difficult to replace.

A made-to-measure round cushion cover refreshes your seating instantly, costs less than replacing the whole cushion, and is a more sustainable choice.

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

Ordering your circle cushion cover is simple:

  1. Select your unit of measurement

  2. Enter the diameter and thickness of your circular cushion

  3. Choose your cover style and fabric

  4. Add any notes, such as zip placement or contrasting fabrics

  5. Add to cart and we’ll take care of the rest

Why Choose Foam4U?

At Foam4U, we specialise in made-to-measure round cushion covers and awkward shapes that others shy away from. With decades of experience, skilled craftsmanship, and UK-based manufacturing, your circle cushion cover is in safe hands.

To make choosing even easier, we guide you toward fabrics that genuinely perform. For indoor use, our most popular choice is Keylargo fabric from the Warwick Fabrics collection — a durable, comfortable upholstery fabric that works beautifully for everyday seating, window seats and decorative circular cushions. It offers an excellent balance of softness, strength and colour choice, making it a firm customer favourite.

For outdoor spaces, campervans and marine settings, we consistently recommend Agora Liso outdoor fabric. This premium fabric is UV-resistant, water-repellent and colourfast, making it ideal for round cushion covers that need to withstand sun, moisture and regular use without fading or degrading.
