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.
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.
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.
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.
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.
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.
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.
We’ve stripped away the confusion. Ordering your T-shaped cushion cover is simple:
Choose your measurement units — mm, cm or inches
Enter your cushion’s lengths, widths, depths, and note the T-shape layout
Pick your preferred style, fabric, and any extras
Add any notes (e.g. which side is the front, zip position, fabric sides)
Click “Add to Cart” — and we’ll handle the rest
