Description
Standard cushions cannot fill a trapezoid bay window seat. The angled sides leave triangular gaps at the corners, a rectangular pad slides toward the center panel, and the whole window seat looks unfinished no matter how you position it. Custom bay window seat cushions cut to your exact angles are the only way to make the seating look built-in.
USCUSHION cuts each bay window seat cushion to your exact angles and dimensions. You measure the front edge, the back edge, and the depth of each angled panel, and we cut the trapezoid precisely to match. Order the full three-panel bay window set together and every piece arrives in the same fabric from the same dye lot, so the seating reads as one designed area across the whole window rather than pieces pushed together to approximate a fit.
Why customers choose us for bay window cushions:
- Cut to your exact trapezoid: Provide the front width, back width, and depth for each angled panel and we cut to your specific bay window geometry — no gaps at the corners, no overhang at the sides.
- Full bay window sets matched: Order the center and both angled side cushions together and every piece arrives in the same fabric and dye lot so the bay looks like a single designed seat.
- Sun-resistant fabric options: Bay windows get concentrated UV; choose fade-resistant fabrics that hold color through daily morning and afternoon sun.
- High-density foam that holds its shape: An HD foam core stays supportive through years of daily use in a reading nook or living room bay window seat without compressing flat at the angled edges.
- Cover + foam, removable: Every cushion is the complete unit — cover and foam together — with a YKK zipper cover that comes off for washing without replacing the foam.
How to Measure a Bay Window Seat Cushion
A bay window seat is usually three panels — a wide center and two angled sides. Measure each panel separately: its front width, back width, and depth, plus the angle where the panels meet (most bays are 135 degrees, but measure yours). Order it as separate trapezoid sections or as one shaped cushion that follows the whole bay. If the shape is unusual, trace it on kraft paper and send us the template.
