Custom Window Seat Cushion Sets — Seat and Back, Any Size & Fabric

A window seat with just a seat pad leaves your back against a hard wall or cold glass. Standard cushions come as single pads, so most window seats never get the back cushion that makes them comfortable. The seat looks half finished and feels worse.

USCUSHION makes the seat and back as a matched set, both cut to your dimensions. You give us the seat size and the back height, choose one fabric and foam, and the set arrives ready to turn the window seat into a spot you actually want to sit in.

Why customers choose us:

• Seat and back as a set: Both pieces cut to your exact size and finished in the same fabric and dye lot.
• Cut to your window: The seat fits the bench and the back fits the wall behind it, with no gaps.
• Foam for each job: Firmer foam for the seat, softer for the back, so each piece feels right.
• Sun-resistant fabric: Both pieces hold color against the daily sun a window seat collects.
• Removable zip covers: YKK zipper covers come off for washing on both the seat and the back.

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

A window seat set against a wall needs more than a seat pad. A matching back cushion turns a hard ledge into a real place to lean and relax. A custom window seat cushion set gives you the seat and the back cut to your exact dimensions, in one fabric, so the whole seat looks built for the space.

Perfect for:

• Window seats with a back where the bench sits against a wall and needs a cushion to lean on
• Reading nook window seats where a seat and back set makes long sitting comfortable
• Bench window seats used as casual seating where a back cushion adds real support
• Sun-facing window seats where seat and back need the same fabric to hold color together
• Window seat sets replacing a worn pad where you want to add a back cushion this time

For the seat section on a curved or angled window, pair this with our custom bay window trapezoid cushions. Order the seat and back together and they arrive matched in one fabric.

Window seat cushion sets suit reading nooks, living room bays, and bedroom window seats set against a wall. The matching seat and back work with modern, traditional, and cottage decor, turning a bare ledge into comfortable everyday seating.

A window seat set has two pieces that sit side by side in the same light, so matching fabric matters. The seat takes the weight and the back takes the lean, and both face the sun from the window. Our catalogue covers fabrics that wear evenly across both pieces.

All fabrics are:

• Fade-resistant so the seat and back hold the same color through daily sun from the window
• Easy to wipe clean after everyday use in a living room or bedroom window seat
• Soft and comfortable for both sitting and leaning during long sessions
• Durable enough for daily family use across both the seat and the back
• Available in a wide range of colors so the set reads as one built-in piece

For sunny windows, a solution-dyed performance weave keeps the set matched. For softer rooms, velvet and linen give the seat and back a warm, finished look.
