Finding the right outdoor cushions for non-standard furniture is frustrating. Most stores only sell fixed sizes — leaving gaps, overhangs, or cushions that slide off. At USCUSHION, every cushion is cut to your exact measurements: width, depth, and thickness you specify.
Choose from 50+ performance fabrics including Sunbrella, marine vinyl, and pet-friendly options — all tested for UV resistance, fade protection, and easy cleaning. Whether you need patio seat cushions, chaise lounge pads, or deep-seat replacements, we make it to fit.
Ships in 5–7 business days. Free shipping on all orders. Backed by a 3-year warranty.
Measure the seat area: width (side to side), depth (front to back), and your preferred thickness. Round to the nearest 0.5 inch. Our product pages walk you through each measurement step.
Sunbrella and solution-dyed acrylic fabrics are the gold standard for outdoor use. They resist UV fading, mold, and moisture. Marine vinyl is ideal for boat and poolside settings.
Most orders ship within 5–7 business days. Rush options are available at checkout for select fabrics.

About this collection
Custom Window Seat Cushions for Every Shape and Scene
Window seats rarely match standard cushion dimensions. A built-in bench in a reading nook, a bay window with angled returns, or a breakfast nook with a fixed seat depth all need a custom window seat cushion cut to the actual space. Most window seats run 18 to 24 inches deep and 36 to 72 inches wide, but custom nooks can be any dimension — which is why a made-to-measure cushion is almost always the right call over an off-the-shelf pad that leaves gaps or hangs over the edge.
Window seats also sit directly in sunlight for much of the day. Sunlight exposure near windows requires fabrics with strong fade resistance and UV protection , which is why fabric choice matters as much as size. This collection covers every window seat configuration — general bench sizes, trapezoid bay windows, nook and niche shapes, cover replacements, and tufted finishes.
Browse by Window Seat Type
- Window Seat Cushions — the general-purpose custom window bench cushion for any straight rectangular seat, available in every fabric and foam option.
- Trapezoid Bay Window Cushions — cut to your exact angle and width for angled bay window seats where standard rectangular cushions leave uncovered corners.
- Window Seat Nook Cushions — sized for reading nook and breakfast nook window seats, including non-standard depths and widths that built-in nooks often require.
- Tufted Window Seat Cushion — a tufted finish option for window seats that serve as a design focal point in living rooms, bedrooms, or entryways.
- Window Seat Cushion Cover — a replacement cover cut to your existing cushion dimensions, for when the foam is still good but the outer fabric needs replacing.
Fabric Options for Window Seat Cushions
Window seats sit in direct sun for hours each day, which rules out fabrics that fade quickly. Solution-dyed acrylic fabrics handle direct sunlight without color loss, repel water, and clean easily — a practical choice for any window seat regardless of room type. For bedroom and living room window seats used mainly for reading or lounging, softer upholstery fabrics like velvet and linen-look weaves are available in the same custom sizing. Breakfast nook and kitchen window seats benefit from stain-resistant performance fabrics that hold up to daily use and spills. Every cover includes a removable YKK zipper so the fabric can be washed or swapped without replacing the entire cushion.
Foam Thickness for Window Seat Cushions
The right thickness depends on how the seat is used and how much clearance there is between the bench surface and the windowsill. For everyday seating like a breakfast nook, 2-inch medium-density foam provides enough support without sitting too high. For reading and lounging, 4-inch foam delivers the comfort needed for extended use. Cushion thickness of 3 to 4 inches is ideal for most window seats — thinner cushions feel hard, and thicker ones raise the seating height uncomfortably close to the sill. For bay window trapezoid seats that are primarily decorative, a 2 to 3 inch profile keeps the cushion proportional to the angled frame.
