Description


Custom Mitred Bench Cushion Covers – Precision-Made to Fit, Built to Last

When your bench seating has mitred corners, standard cushion covers simply don’t cut it. That’s where we come in. Our made-to-measure mitred bench cushion covers are designed to follow your angles precisely, offering a smart, seamless fit that ties the whole space together.

Whether you’re fitting out a built-in dining bench, fine-tuning an L-shaped camper setup, or giving your boat’s saloon a proper finish — mitred covers make all the difference.


Tailored for Angles, Not Guesswork

Unlike generic options that only come in square or rectangular shapes, our covers are custom-cut based on your exact dimensions — including those tricky mitred corners and joins. As a result, you avoid the usual hassle: no baggy sides, no awkward gaps, and no “close enough” fabric fudging.

Instead, you get a clean, accurate fit that hugs the space perfectly — every time.


Choose a Style That Works for You

Once you’ve nailed the fit, it’s time to think about style. After all, function matters — but so does finish. That’s why we offer a range of styles, so your cushions not only sit right, but look the part too:

  • Wrap Style – neat and understated, ideal for modern settings

  • Box Style – adds crisp edges and structure

  • Box with Piping – offers a more traditional, tailored look

  • Box Pleat Style – elegant, detailed, and classically styled

Whichever you choose, each cover is cut and sewn by hand right here in the UK — so there’s no skimping on craftsmanship or fit.


Fabrics That Suit Your Setting

Next, let’s talk materials. Once you’ve chosen your style, the right fabric brings the whole thing to life.

  • For outdoor or mobile spaces (boats, vans, caravans), we recommend UV-stable and water-resistant fabrics built to handle the elements.

  • For indoor use, we offer soft, hard-wearing options — from plush velvets to woven cottons and easy-care blends.

What’s more, you can even specify different fabrics for each side — great if you want a reversible look or a seasonal refresh.

Still deciding? No problem — we’ll send free samples so you can see and feel the options before committing.


Need New Foam Too? We’ve Got You Covered

If your cushion inserts are worn out, there’s no sense in putting a new cover on a tired core. That’s why we also supply custom-cut foam, made to match your mitred measurements exactly.

Choose from:

  • High-density foam for firmer, more structured support

  • Reflex foam for a softer, more laid-back feel

Additionally, we can wrap your foam in Dacron or Stockinette, making the cushion easier to insert and giving it a fuller, rounder shape.


Practical Features That Make Life Easier

We’re not just about looks — we also think about the day-to-day. That’s why we include thoughtful design features that make a real difference:

  • Choose where your zip goes for easy removal

  • Add a non-slip base, especially useful in boats or mobile homes

  • Include Velcro tabs, ties, or fastenings to keep everything in place

On top of that, all our covers are removable and washable, making maintenance quick and easy.


A Smarter, More Sustainable Option

Let’s be honest — throwing out a perfectly good cushion just because the cover’s worn isn’t just wasteful, it’s unnecessary. A custom mitred cover gives your seating a fresh lease on life — without the cost or hassle of starting from scratch.

Especially in built-in seating areas or tight corners where replacements are hard to find, going custom is the most sensible and sustainable option.


Ordering Made Simple

We’ve taken the guesswork out of it. Here’s how to order your mitred bench cushion cover:

  1. Choose your preferred units — mm, cm, or inches

  2. Enter your cushion’s length, width, depth, and mitred angles

  3. Pick your cover style and any extras you’d like

  4. Add any notes or preferences (zip location, front-facing edge, fabric sides, etc.)

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

And if you’re unsure? Just give us a shout. We’ll guide you through the measuring and fabric choices so you get it right the first time.


Why Foam4U?

At Foam4U, we bring together traditional upholstery craftsmanship with modern precision tools. This means your cushion cover isn’t just well-made — it’s built to fit and built to last.

No more slipping, sagging, or settling for second-best.
Just spot-on, made-to-measure covers that do the job right.

So whether you’re sprucing up your home bench, refitting your camper, or upgrading your boat interior — a mitred bench cushion cover from Foam4U is the smart finishing touch.

Proudly handmade in the UK, and built the way things used to be — properly.
