Measure the usable flat seating surface inside the window seat or built-in bench. Record the length, depth and desired thickness in inches. Measure at more than one point if the seat is not perfectly square, then use the smallest usable measurement so the finished cushion has room to sit flat.

A custom window seat cushion can work for many bay windows and built-in seating areas. Before ordering, confirm whether your seat is rectangular or has angled, curved or irregular sections. If the shape is unusual, contact Favoyard before placing an order so you can confirm the best approach for your project.
