Description

Custom T-Shaped Cushion Covers – Expertly Tailored, Built to Fit

T-shaped cushions are a devil to cover with anything off the shelf. Whether it’s the armrest cut-outs on an old armchair or the wraparound seat in a caravan, these shapes demand precision — not compromise. That’s where our made-to-measure T-shaped cushion covers come in.

So if you’re restoring a beloved chair, fine-tuning your boat cushions, or updating an LHF/RHF bench with a leg cut-out — this is the tailored solution you’ve been looking for.


Covers That Follow Every Contour

T-shaped cushions are nothing like the standard square or rectangle. They’ve got cut-outs, protrusions, and angles that don’t play nice with generic covers. But that’s exactly our specialty.

We make your cover to the exact measurements you provide — so it fits perfectly around every edge and corner. No more bunching, no awkward stretching, and definitely no “that’ll do” attitude.

Instead, you get a crisp, professional finish that fits like a glove — because it’s made just for you.


Style Options That Work With Every Setup

It’s not just about getting the fit right — it’s about looking the part too. So once we’ve nailed your T-shape, you can choose from a range of cover styles to suit the space:

  • Wrap Style – sleek and simple, great for a fuss-free look

  • Box Style – clean lines and solid edges

  • Box with Piping – adds a tailored touch for a smarter finish

  • Box Pleat Style – traditional, detailed, and perfect for classic interiors

Whatever your choice, every cover is hand-cut and sewn here in the UK — with no stock sizes or shortcuts.


Fabrics to Suit Every Use

Once your shape and style are sorted, it’s time to choose the fabric. Whether your T-shaped cushion lives indoors or goes on the move, we’ve got materials that’ll do the job:

  • For boats, campervans, or outdoor use, opt for UV-resistant, water-repellent fabrics that can handle knocks and spills.

  • For indoor comfort, choose from our wide range of soft, durable fabrics like velvet, cotton, or textured weaves.

Even better, you can go two-tone and choose a different fabric for each side — great if you like to mix it up with the seasons.

Still unsure? Ask us for fabric samples — we’ll get them sent out sharpish.


Foam Too? We’ve Got You Covered

There’s no point wrapping new covers around foam that’s gone soft or saggy. We’ll cut new foam to match your T-shape exactly, and you can choose:

  • High-density foam for firm, supportive seating

  • Reflex foam for a softer, more cushioned feel

Plus, we offer Dacron or Stockinette wrapping to help your cushion slide neatly into the cover and keep its shape long-term.


Smart Add-Ons for Daily Use

We know it’s the little touches that make a difference, especially when you’re dealing with unusual cushion shapes:

  • Choose your preferred zip position — front, side, or hidden

  • Add a non-slip base, ideal for use in boats or mobile setups

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

And of course, all covers are removable and washable, so clean-ups are quick and stress-free.


A Proper Alternative to Replacing the Lot

Let’s face it — T-shaped cushions aren’t easy (or cheap) to replace. But in most cases, the foam’s still fine. So instead of tossing the whole thing, just get a new cover made to fit.

It’s better for your wallet, better for the environment, and a lot less hassle — especially for fixed seating or made-to-measure furniture.


Ordering Is Easy – Here’s How

We’ve stripped away the confusion. Ordering your T-shaped cushion cover is simple:

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

  2. Enter your cushion’s lengths, widths, depths, and note the T-shape layout

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

  4. Add any notes (e.g. which side is the front, zip position, fabric sides)

  5. Click “Add to Cart” — and we’ll handle the rest

Need help with measuring or figuring out what fabric to go for? Just give us a ring or drop us a message — we’re here to help.


Why Go with Foam4U?

We don’t mess around with “close enough.” At Foam4U, we combine proper upholstery know-how with precision cutting and quality materials. That means your cover isn’t just made to fit — it’s made to last.

So whether it’s a T-shaped seat on your boat, a vintage armchair, or a custom camper build — we’ll deliver a cushion cover that does the job right.

Proudly made to measure, and made in the UK.
