Standard cushion covers are fine — until you’ve got a seat with a notch in it. Whether it’s a dining bench with a cut-out for a table leg, a campervan seat shaped around a panel, or a boat cushion designed to fit a bulkhead, you need a cover that’s made to fit the shape, not forced to stretch around it.
That’s exactly why we make custom notched cushion covers, cut and sewn to match every internal corner, contour, and measurement. These are not your average covers — they’re proper made-to-measure solutions.
So if your cushion has a notch, we’ve got it covered — literally.
Notched cushions are some of the most awkward out there. They’ve got internal corners, straight lines, and unexpected angles. That’s precisely why off-the-shelf just doesn’t work.
Rather than guessing, we build your notched cushion cover based on the precise dimensions you provide. That means the notch — whether square, rectangular or angled — is cut into the fabric and sewn cleanly, not squeezed in as an afterthought.
As a result, your cover fits snugly around the cushion without pulling, gaping, or bunching. It looks clean. It sits right. It lasts longer.
Of course, once you’ve sorted the fit, it’s time to get the finish right. Every space is different — that’s why we offer a range of styles to help your cushion match the look and feel of your setup.
Wrap Style – simple, modern, and minimal
Box Style – gives your cushion shape and structure
Box with Piping – sharp lines with a classic twist
Box Pleat Style – traditional, smart, and full of detail
Every single cover is handmade in the UK, stitched by skilled craftspeople who know their way around a tape measure.
The perfect shape needs the perfect fabric to go with it. Whether your cushion lives indoors or has to survive life on the road (or water), we’ve got a fabric to match.
For boats, caravans, and outdoor seating, we suggest durable, water-resistant, UV-stable fabrics that stand up to heat, humidity, and wear.
For home interiors, we stock plush velvets, breathable cottons, and a wide selection of textures and tones — all handpicked for comfort and durability.
Plus, you can even opt for a reversible cover with a different fabric on each side — ideal for changing up the look with the seasons or flipping when one side’s due for a wash.
Still unsure? Ask for free samples — we’ll send them out fast.
If your old cushion’s lost its bounce, why stop at the cover? We also offer foam cut to size and shape, including notches, corners, and tapers — all based on the details you provide.
Choose from:
High-density foam – firm and supportive, ideal for structured seating
Reflex foam – softer and springier for relaxed seating areas
Additionally, we can wrap your foam in Dacron or Stockinette to improve the fit and give it a smoother, more professional look.
Let’s be honest — details matter, especially when you’re working with cut-out shapes and complex installs. That’s why we offer practical extras that go the extra mile:
Choose your zip placement for easy access
Add a non-slip base, particularly useful for vehicles, boats, or high-use areas
Include Velcro tabs, ties or fasteners to keep the cushion securely in place
Of course, all our covers are removable and washable, so they’re easy to clean and maintain — even in busy spaces.
If the cushion’s still doing its job, why throw it out just because the cover’s tired? Especially when it’s a pain to replace — notched cushions aren’t exactly easy to find in stores.
Instead, a custom cover lets you keep what’s working and refresh what isn’t. It’s smarter. It’s more sustainable. And it saves you money in the long run.
Ordering a shaped cushion cover might sound complicated — but we’ve made it easy. Here’s how:
Choose your preferred units — mm, cm or inches
Enter your cushion’s lengths, widths, depths, and measurements for the notch or cut-out
Pick your preferred style and fabric
Add any notes or special requests — such as zip location, front-facing side, or fabric preference for each side
Click “Add to Cart” — and let us take care of the rest
If you’re unsure about how to measure, just ask. We’ll talk you through it.
At Foam4U, we don’t just cut fabric — we craft solutions. We take your awkward, oddly-shaped cushion and turn it into something that looks good, fits right, and lasts for years.
With decades of upholstery experience, modern cutting tools, and proper attention to detail, we build custom covers that fit properly — the first time.
So whether you’re fitting out a narrowboat, a campervan bench, a window seat, or a built-in dining nook — if it’s got a notch, we’ve got the answer.
