Custom Hexagon Bay Window Cushion — Made-to-Measure Window Seat Cushion

A bay window seat is one of the hardest to cushion. A box or angled bay has a flat front with two corners that cut back to the wall, making a six-sided shape — also known as a clipped trapezoid seat cushion — so a plain rectangle jams into the angles or leaves triangular gaps, and foam trimmed at home never holds a clean edge.

A Custom Hexagon Bay Window Cushion is built for exactly that seat. You give us the front (bottom) width, the two side heights, the length of each angled corner, and the back (top) width, and we cut the six-sided shape and the foam to match, with the angled corners finished cleanly.

Why customers choose us:

• Exact fit: we cut to your front, sides, angled corners, and back, so the cushion fills the bay with no gaps
• Seat and back together: order matching pieces so the whole window seat lines up
• Foam that lasts: choose the density for light seating or a daily reading nook
• YKK zipper covers: removable covers that unzip for easy cleaning
• Indoor or outdoor: upholstery fabric for a reading nook, performance fabric for a sunny bay window

How to Measure a Hexagon Bay Window Cushion

Measure the front edge, which is usually the widest and faces the room. Then measure each straight side height, the length of each angled corner, and the back edge along the wall. Add the thickness you want. The two angled corners are usually equal, but measure both to be sure. If the shape is unusual, trace it on kraft paper and send us the template.

A Custom Cut-Corner Cushion is a rectangle with the two top corners cut off at an angle. It fits benches and seats that meet a wall on a slant, where a plain rectangle would jam into the corner or leave a triangular gap. You give us the bottom width, the two side heights, the slanted corner length, and the top width, and we cut it to match.

Perfect for:

• Bay window benches where the seat runs wide at the front and the back corners angle into the window frame
• Fireplace hearth cushions that sit along the hearth with clipped front corners
• Window seat cushions in nooks where one or both back corners meet an angled wall
• Entryway and mudroom bench cushions built into a corner with a beveled edge
• Dormer and attic window seats where the roofline cuts the corner of the seat
• Need a straight three-panel bay instead? See our custom bay window trapezoid cushion

Order it as a seat, a back, or both, so the whole bench matches. Send the shape and we cut the foam to fit the first time.

This cushion fits any bench or seat where the top two corners are cut at an angle instead of square. If your seat is widest along the front and the back narrows because one or both corners meet a slanted wall or window frame, the cut-corner shape matches it. To confirm the fit, measure the bottom width, each straight side height, the slanted corner length, and the top width, then send those numbers. It can be made as a seat, a back, or both, indoors or outdoors depending on the fabric you choose.

A cut-corner bench sits in both indoor nooks and sunny window bays, so the fabric catalogue covers both. The right cloth depends on where the bench lives.

All fabrics are:

• Fade and UV resistant, so a cushion in a sunny bay window holds its color
• Easy to wipe clean, for entryway and mudroom benches that see daily traffic
• Moisture and mildew resistant for window condensation or a covered porch
• Built to take daily sitting without thinning at the angled edges
• Offered in a wide range of solids and patterns to match trim and walls

For a bright bay window seat, choose a fade-resistant performance weave. For an indoor entryway or reading nook, soft upholstery fabrics and faux leather give a tailored, lasting finish.
