Custom LHF Corner Sloped Back Cushion Covers – Made to Fit Even the Most Awkward Corners

LHF corner cushions are already tricky — throw in a sloped back, and now you’ve got a shape that most covers simply can’t handle. Whether it’s a wraparound seat in a motorhome, a corner bench in a narrowboat, or a bespoke installation at home, standard solutions just won’t do.

That’s why we offer made-to-measure LHF Corner Sloped Back Cushion Covers — crafted to follow every curve, slope, and angle. Built to your exact dimensions, these covers give your corner cushions the clean, tailored finish they deserve.

So if you’ve got a left-hand-facing (LHF) corner back cushion with a sloped angle, you’re in the right place.


Shaped for Angles – Cut to Your Spec, Not the Shelf

LHF sloped cushions combine a lot of elements — a directional layout, a backrest incline, and a precise corner join. Off-the-shelf? Forget it. Even basic square covers can’t keep up.

That’s exactly why we work to your measurements, not generic templates. We cut and shape the fabric to your specs — including slope depth, seat height, and any mitred or corner joins.

As a result, the cover sits flush, fits properly, and looks like it belongs there — because it does.


Choose a Style That Complements Your Space

Beyond function, your corner cushions need to look the part. That’s why we offer four distinct cover styles — each designed to match different aesthetics:

  • Wrap Style – minimal and contemporary, perfect for simple setups

  • Box Style – structured, clean, and sharp-edged

  • Box with Piping – a polished finish with classic detailing

  • Box Pleat Style – traditional, textured, and full of character

Each one is made to order by our skilled UK upholstery team — no shortcuts, no compromises.


Fabrics That Work as Hard as Your Cushions Do

Choosing the right material is just as important as getting the shape right. Depending on where your cushion lives, we’ll help you match form with function:

  • For outdoor or mobile use — such as boats, caravans, or campervans — choose from our tough, UV-stable, and water-resistant fabrics

  • For indoor seating — like corner nooks or kitchen benches — go for soft velvets, natural cottons, or woven blends in a wide range of colours

Even better, we offer the option for reversible covers — two different fabrics, one on each side — so you can switch up the style whenever you like.

Still unsure? No problem — we’ll send you fabric samples, free of charge.


Need Foam Too? We’ll Match That Sloped Profile

If the foam in your LHF corner cushion has gone flat or out of shape, don’t worry — we also supply custom-cut foam inserts, shaped to follow your sloped backrest exactly.

Choose from:

  • High-density foam – firm, supportive, and great for upright seating

  • Reflex foam – a softer option for more relaxed seating areas

And for a perfect finish, we can wrap your foam in Dacron or Stockinette to plump it out and make it easier to fit.


Smart Finishing Touches That Make Life Easier

We know this shape is tricky, so we include optional extras that help your cushion stay where it should — and make maintenance a breeze:

  • Choose your zip placement for straightforward removal and refitting

  • Add a non-slip base — especially useful for cushions in boats, vans, or high-traffic zones

  • Include Velcro tabs, ties, or fixing straps to keep your cushion secure

And yes — every cover is fully removable and washable, making cleaning simple and stress-free.


Why Replace When You Can Refresh?

Let’s face it — finding a replacement LHF sloped corner cushion is near impossible. But chances are, the foam is still doing its job.

So instead of throwing away the whole cushion, a made-to-measure cover lets you give it a new lease of life. It’s the practical, affordable, and sustainable way to upgrade your space.


How to Order Your LHF Corner Sloped Back Cushion Cover – Quick, Easy, and Accurate

We’ve taken the hassle out of ordering. Just follow these steps:

  1. Select your measurement units — mm, cm or inches

  2. Enter your cushion’s length, width, depth, and the details of the slope and corner layout

  3. Pick your cover style, fabric, and any extras

  4. Add any special instructions (e.g. zip location, front-facing edge, reversible fabric request)

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

If you’re unsure how to measure the slope or layout, just ask us — we’re always happy to help.


Why Choose Foam4U?

At Foam4U, we don’t do guesswork — we do things properly. Our team has decades of experience creating cushion covers that are built to fit, made to last, and designed to look good doing it.

We use traditional upholstery craftsmanship, modern cutting tools, and top-notch materials to deliver a result that’s head and shoulders above the rest.

So whether you’re kitting out a camper, fitting cushions into your boat, or adding comfort to your corner seating at home — our LHF Corner Sloped Back Cushion Covers are the finishing touch you’ve been looking for.

Made to measure.
Made in the UK.
