Custom Bay Window Cushions — Seat Pads & Corner Wedges

Factory-direct, cut to your bay — front pads plus corner wedges at any angle you measure.

A bay window is three window seats and two corner turns — which is exactly why stock cushions fail at it. The front panel is never quite the width of the glass, and the corners aren’t square: most bays angle at 30, 45, or 60 degrees, and a rectangular pad bunched into that corner never looks right for long.

We cut bay window cushions the way the window was built: one front pad to your exact width, plus two corner wedges cut to your actual angle — measured in one pass with a protractor or a piece of paper. All three pieces in the same fabric and foam, finished with welt edges or rounded fronts to echo the architecture. Made to order by the factory, shipped as a set that drops straight into the bay.

Build Your Bay Window Cushions

Start with a corner wedge — enter your angle and both widths, and see the piece drawn to scale.

Front width, rear width, and your measured angle in degrees — the drawing updates as you type, and the same order holds all three pieces in one fabric lot.

Straight front section? Switch to Rectangle in the same customizer for that piece.

Pricing — estimated starting at (per piece)

Piece / fabric tierCotton LinenPerformanceSunbrella
Corner wedge (e.g. 24 × 16 avg × 24 deep)$112$137$169
Front pad (e.g. 60 × 20)$197$252$322

*Each piece: $39 make-base + top area × fabric rate ($19.0/$25.5/$34.0 per sq ft) × 1.15 wedge factor on the corners. Order all three pieces together in one fabric and one dye lot. Every dimension is confirmed with you before we cut.

For comparison: U.S. custom-configurator specialists’ 2026 listings for made-to-order cushions in common sizes (16×16 through 24×24) run roughly $71–$119 before shipping — and most only reveal that price after a quote request. We publish the formula above so you can check the math before you order.

Yours differs? That’s the point — we cut to your numbers.

How to Measure a Bay Window Seat

  • Measure the corner angle first: press a piece of paper into the corner, crease it, and read the fold with a protractor — or use a phone angle app. Most bays are 30°, 45°, or 60°; confirm before you order, not after.
  • Front width goes clear edge to edge — from where the wedges start on the left to where they start on the right.
  • A curved bay is a bow window, not a true bay: those are built from multiple narrow rectangles, not wedges.
  • Order all pieces in one fabric and one dye lot so the three sections read as a single run.

Fabric on Three Sides of Glass

Bay windows face glass on three sides — the strongest light exposure of any seat in the house. Colorfastness leads the recommendation: solution-dyed acrylic (Sunbrella’s indoor line) holds its color where ordinary weaves bleach within a year, and performance weaves cover the mid-tier. Whatever you choose, all three pieces come cut from the same lot — one fabric, one dye run, no shade shift from wedge to wedge. See the full fabric guide for the tier-by-tier comparison.

Frequently asked questions

How do I measure the corner angle of my bay window?

Three ways, easiest first: hold a piece of paper into the corner, crease it, and measure the fold with a protractor; use a phone angle app; or measure both edges off a known square. Most bays are 30°, 45°, or 60° — but confirm before you order, not after.

Do I need separate cushions for the corners?

If your bay has angled side walls, yes — wedge cushions fill the corners so the front pad runs straight. If your bay is a curve (a bow window), we cut multiple narrow pads instead. Send a top-view sketch and we’ll map the pieces with you.

Can the front cushion follow a curved bay?

Yes — choose a bowed front on the front pad, or for full bow windows we divide the run into segments so the whole seat follows the curve. Both options start with the same measurements.

Can I order standard bay window cushion sizes?

Standard sizes too — in 3 clicks, for the straight front pad — common runs land 16–24 inches deep at 3 thick, and typing the numbers in gets the same instant factory-direct quote, never out of stock. The corner wedges are the custom part: angles vary house to house, which is exactly why we cut to measurements.
