Triangle cushions — answered
Can you match an unusual triangle angle?
Yes. We cut right-angle and equilateral triangles to the exact edge lengths you enter, so the cushion fits your corner bench, bay or bow precisely. For a non-standard angle, send a photo on WhatsApp and we'll size it before we make it.
How do I measure a triangle cushion?
Measure the two straight edges that form the corner — usually a base and a height — plus the thickness, rounding to the nearest cm or quarter inch. Every cushion is cut to ±1 cm. If one edge is curved, note that and we'll advise.
Foam or fiberfill for a triangle cushion?
High-density foam suits corner seating you use daily; fiberfill is softer for a decorative accent or occasional nook. Both are options when you customize.
Can I get a triangle cushion for outdoors?
Yes — choose a water-resistant, UV-stable outdoor fabric and quick-dry foam for decks, boats and patios.
How long does it take and do you ship to me?
Each cushion is made to order and shipped worldwide with free, tracked delivery — you'll see the current lead time at checkout. If the fit isn't right, our 14-day perfect-fit guarantee means we remake it.
