Description

Custom L-Shaped Cushion Cover – Built to Fit, Styled to Last

Standard cushion covers don’t stand a chance with L-shaped seating. Corners, angles, and wraparounds all need proper attention — not one-size-fits-all solutions. That’s where our made-to-measure L-shaped cushion covers come in.

Whether you’re kitting out a corner bench at home, an L-shaped motorhome seat, or the saloon of your boat — we’ll tailor a cover that fits like a glove and looks the part.


Designed Around Your Corners

L-shaped cushions don’t play by the rules — so neither do we. Our covers are cut to your exact measurements, shaped to wrap smoothly around every angle and junction.

So instead of pulling, gaping, or sagging in the corner, you get a crisp, continuous fit that hugs your cushion all the way around — and actually stays put.

No guesswork. No bodging. Just a professional finish.


Pick a Style That Works With Your Space

Function comes first, but the finish matters too. That’s why we offer a range of styles to help your L-shaped cushions blend in — or stand out — exactly how you want them to:

  • Wrap Style – clean lines and a modern feel

  • Box Style – for structure and definition

  • Box with Piping – classic detailing that elevates the look

  • Box Pleat Style – traditional and refined, with added depth

Each cover is handmade to order by our experienced team in the UK — no shortcuts, no off-the-shelf fluff.


Fabrics That Fit the Job (and the Look)

Whatever space you’re working with, we’ve got the right fabric for the job:

  • For caravans, boats, or campervans, we recommend our tough, UV-stable, and water-resistant fabrics — built to handle moisture, heat, and motion.

  • For indoor use, choose from plush, comfortable options like velvet, cotton, or textured weaves — all available in a range of colours to suit your setup.

And if you like a little flexibility, go reversible. We can make each side in a different fabric so you can flip the look with the seasons.

Still unsure? Ask us for samples — we’re happy to send them out.


Foam Inserts Cut to Match Your L-Shape

Got saggy cushions or foam that’s lost its bounce? No problem — we don’t just make covers, we cut foam too.

We’ll shape new foam inserts to your exact L-shaped spec, and you can choose from:

  • High-density foam for firm support

  • Reflex foam for a bit more give and softness

To finish it off, we offer Stockinette or Dacron wrapping — making the cushion easier to fit and giving it that smooth, full look.


Smart Extras That Make Life Easier

Because we’ve been at this a while, we know the little things make a big difference:

  • Choose where you want the zip for easy fitting

  • Add a non-slip base — ideal for boats and motorhomes

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

And yes, all covers are removable and washable — because life gets messy.


An Efficient, Eco-Friendly Upgrade

Tossing a whole cushion just because the cover’s gone? Not on our watch. A custom L-shaped cover lets you breathe new life into the cushions you’ve already got.

Especially in built-in seating areas or oddly shaped spaces, a tailored solution just makes sense — it saves time, saves money, and saves waste.


How to Order – Quick and Straightforward

We’ve made it easy — no confusion, no back-and-forth. Just follow these steps:

  1. Select your units – mm, cm, or inches

  2. Enter your cushion’s lengths, widths, depths, and layout shape

  3. Choose your style and any extras

  4. Add notes (e.g. zip position, which side is front-facing, or fabric on each side)

  5. Click “Add to Cart” and let us take care of the rest

Need help measuring? Get in touch — we’ll talk you through it.


Why Foam4U?

At Foam4U, we take pride in doing things the proper way. That means no slapdash templates or imported knock-offs — just solid British craftsmanship, built to your specs and finished by hand.

So whether you’re remodelling a van, fitting out a boat, or refreshing a kitchen bench, we’ll deliver a cover that fits, lasts, and looks great doing it.

Proudly designed, cut, and sewn in the UK.
