Indoor Rectangular Window Seat Cushions

Some bay windows have a flat centre section rather than angled sides throughout, and a rectangular cushion suits this straight-edged part of the seat. Entering your own length, width, and thickness lets you create a cushion that follows the flat section of the bay rather than settling for an approximate off-the-shelf size.

Choose from our range of indoor fabrics, with Dacron wadding included as standard, for a softer feel in a spot that gets everyday use.

A window nook built for reading needs a cushion that's thick enough to sit comfortably in for long periods, rather than a thin decorative pad. Custom dimensions let you match the exact width and length of your nook, so the cushion sits flush without gaps at either end.

Select high-density comfort foam for a supportive seat, or comfort-plus foam for a softer feel, and add ties or sewn Velcro to keep the cushion in place.

Banquette seating and built-in dining benches that run beneath a window usually follow a straight line along the wall, making a rectangular cushion the right shape for a close, gap-free fit. Custom dimensions let you match the exact length of your bench, including longer runs that off-the-shelf cushions rarely cover.

Add piping for a tailored finish, or choose commercial-grade foam for banquette seating in busy family kitchens or dining areas that need to withstand daily use.

A rectangular window seat cushion suits window seats with straight front and back edges. If your window seat has angled sides, such as a bay window, our indoor trapezium window seat cushion is designed to follow that angled shape. If your window seat wraps around a corner where two walls meet, our left or right mitred window seat cushion is designed to follow that corner.
