Custom Bow Window Cushions — Curved Window Seat, Any Size & Fabric

A curved bow window seat is one of the hardest seats to cushion. The arc means a standard cushion touches only at the middle and gaps at both ends, and cutting a rectangle down never follows the curve cleanly. The seat ends up looking unfinished no matter how you angle the pad.

USCUSHION cuts each bow window cushion to follow your seat's curve. You give us the measurements along the arc, choose your foam density and fabric, and the cushion arrives shaped to sit flush against the whole window.

Why customers choose us:

• Cut to your curve: We shape the cushion to the arc of your bow window, so it sits flush with no gaps at the front edge or corners.
• Seat and back together: Add a matching back cushion in the same fabric and dye lot for a built-in look around the whole curve.
• Sun-resistant fabric: Choose fabrics that hold color against the heavy sun a bow window collects all day.
• Foam that holds its shape: A high-density core stays supportive along the curve through years of daily use without flattening at the edges.
• Removable zip covers: YKK zipper covers come off for washing, so a curved bow window cushion stays fresh without replacing the foam.

Every bow window cushion is made to order. See more shapes in our custom window seat cushions collection.

A bow window curves. Four, five, or six windows join in a smooth arc, and the seat below follows that same curve. A straight, rectangular cushion cannot sit on a curved bow window seat without leaving triangular gaps along the front edge or bunching in the middle. A custom bow window cushion is cut to follow the arc of your seat, so it sits flush from wall to wall.

Perfect for:

• Curved bow window seats where four to six windows form a continuous arc and the seat curves with them
• Bow window bench cushions for living room and bedroom bay areas used as a daily reading or lounging spot
• Curved window seat cushions for older homes where the alcove was built with a gentle bow rather than sharp angles
• Sun-facing bow windows where the fabric needs to hold color against concentrated light across the whole curve
• Bow window seat replacements where the frame is solid but the original foam has flattened along the curve

If your window seat has sharp, angled corners instead of a smooth curve, our custom bay window trapezoid cushions are cut to those exact angles instead. Order a seat cushion on its own, or add a matching back cushion for a bow window seat set against the wall.

Bow window cushions suit living room, bedroom, and dining bay areas built with a curved window alcove. They work with modern, traditional, and cottage decor, turning a curved bow window into a comfortable everyday seat.

A bow window wraps a lot of glass around one seat, so the cushion sits in direct sun for much of the day. The fabric matters as much as the fit. Our catalogue includes weaves that hold up to that daily sun while staying soft enough for a spot you actually want to sit in.

All fabrics are:

• Fade-resistant under the concentrated sunlight a curved bow window collects across the full day
• Easy to wipe clean after everyday use in a living room or bedroom window seat
• Soft and comfortable for long reading or lounging sessions in the curve of the window
• Durable enough for daily family use, including kids and pets who claim the window seat
• Available in light neutrals that suit natural window light, or richer tones that make the bow window a feature

For south and west-facing bow windows, a solution-dyed performance weave holds color best. For shaded or north-facing windows, velvet and linen give the warmest, most finished look.
