Description

Custom Equal-Sided Taper Cushion Covers – Made to Fit, Built to Last

Got cushions that taper evenly on all sides? Standard covers don’t stand a chance — but we’ve got the solution. Our made-to-measure equal-sided taper cushion covers are expertly crafted to hug every angle, offering a clean, snug fit wherever you need it.

Whether you’re refreshing your boat cabin, revamping your campervan, or upgrading a bespoke bench at home — if it’s tapered, we can cover it.


Made for Angled Cushions, Built Around You

Unlike generic covers, ours are tailored to the exact dimensions you provide — including those tricky taper angles. This means no bunching, no awkward corners, and no fighting with fabric that doesn’t quite sit right.

Instead, you get a crisp, professional finish that follows every line of your cushion — even on all four sides.


Choose a Style That Suits Your Space

To make sure your cushions don’t just fit well, but look the part too, we offer a variety of cover styles — each with its own character:

  • Wrap Style – streamlined and understated, great for modern spaces

  • Box Style – adds form and definition, ideal for built-in seating

  • Box with Piping – introduces a touch of tailored detail

  • Box Pleat Style – elegant and traditional, with a decorative edge

No matter your taste, every cover is individually cut and sewn by our skilled UK team — no shortcuts, no generic sizing.


Fabrics to Match Any Environment

Once you’ve chosen your style, it’s time to pick a fabric. And here’s where you can really make it your own.

  • For outdoor or mobile use (boats, vans, caravans), we recommend UV-stable, water-resistant materials that stand up to the elements.

  • For indoor seating, we’ve got a wide choice of plush, durable fabrics — from tactile velvets to woven cottons.

Better still, you can even choose a different fabric for each side — perfect for a reversible look or seasonal switch-up.

Not sure what works best? We’ll send out free samples to help you decide.


Need New Foam Too? We’ve Got That Covered

If your cushion inners are past their prime, why stop at the cover? We also offer foam cut to size, shaped precisely to match your taper specs.

You can choose from:

  • High-density foam for a firmer, structured feel

  • Reflex foam for something a bit softer and more forgiving

Additionally, we can wrap your foam in Stockinette or Dacron to give a plumper shape and a smoother fit.


Small Features, Big Difference

We’ve thought through the details — so you don’t have to:

  • Select your preferred zip position for easy access

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

  • Include Velcro, tie-backs, or other fixings to keep everything in place

And yes — all our covers are removable and washable, so they’re easy to keep looking fresh.


A Smarter Way to Upgrade

Let’s be honest — chucking out a cushion just because the cover’s gone isn’t just wasteful, it’s expensive. A new, custom-fit cover gives new life to what you already own.

Especially in spaces with fixed or hard-to-replace seating (we’re looking at you, narrowboats and campervans), a made-to-measure cover isn’t just the best choice — it’s the only one that makes sense.


How to Order – Simple and Straightforward

We’ve taken the guesswork out of the process. Here’s how to order:

  1. Choose your units — mm, cm or inches

  2. Enter your cushion’s length, width, depth, and taper measurements

  3. Select your cover style and any extras

  4. Add any special instructions (e.g. zip side, fabric sides, etc.)

  5. Click “Add to Cart” — and leave the rest to us

Need help? Just shout — we’re happy to walk you through it.
