Custom Bay Window Seat Cushions

Bay window cushions — answered
Should I get one cushion or a three-section set for my bay?
Both fit an angled bay. A single trapezoid cushion looks seamless; a three-section set (one per pane wall) is easier to lift for storage below and hugs each angle precisely. Most bays suit the 3-section approach — tell us which you prefer.
How do you handle the angled corners?
We build the trapezoid and angled shapes into the cushion from your front and back widths, so the front edge follows the glass and the back sits flush to the wall with no triangular gaps.
How do I measure a bay window seat so the fit is right?
Measure the front and back width of each angled section and the depth into the corners, rounding to the nearest cm or ¼ inch. Every cushion is cut to ±1 cm. Not sure on the angles? Send a photo on WhatsApp and we work them out before we make it.
How thick should a bay window cushion be?
2–3″ of high-density foam gives a firm, comfortable perch without sitting too high in the window; go to 4″ if you'll lounge in the bay. You set the exact thickness when you customize.
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.
