Every photograph here is a real window seat cushion made to measure, read line by line by one of the seven masters. For sizes, foam and fabric, start at the Cushion Atlas page.
Will my cushions be made to the exact size I give, or rounded off? My window frame also sticks out a little.
The workshop's answer
Exactly as written. Seats of 22 x 99.5 in (56 x 253 cm) and 22 x 98.5 in (56 x 250 cm) were produced to those numbers, not rounded. For a frame that juts out about 3/4 in (2 cm), send a photo; a notch or an angled edge is no trouble with a drawing that shows the measurements.
Can you check my measurements and settle the final size for me? And is your mockup drawing exact?
The workshop's answer
The workshop makes the cushion strictly to the dimensions you give and cannot decide the final size for you. It will turn your numbers into a drawing so you can check the shape, but you confirm the numbers. The surest route is to sketch the final measurements on paper and send a photo of the sketch.
Can I buy just the L-shaped backrests and use them on my daybed?
The workshop's answer
Yes, choose the L-shaped backrest in the options. Each one covers a 39 x 39 in (99 x 99 cm) corner, so two of them span a 39 x 79 in (99 x 201 cm) sofa. One buyer used a pair on a 75 x 38 in (191 x 97 cm) daybed from another brand.
