custom cut foam window seat cushion

A custom cut foam window seat cushion turns an awkward ledge into the coziest spot in the house. Standard cushions rarely match the odd angles of a bay window or built-in nook. Foam cut to your exact measurements fills the space edge to edge, so the seat looks tailored and stays put.

Getting the Fit Right

Measure the length and depth of your seat at several points. Walls and window frames are seldom perfectly square. Note any angled corners or notches so your window seat foam can be cut to size and match the true shape.

Choosing Thickness and Firmness

• Thickness: Thicker foam feels plush for lounging. Thinner foam keeps the seat low beneath a window sill.
• Density: High density upholstery foam resists sagging and holds its shape through daily use.
• Wrap: A layer of batting softens the edges and helps the cover fill out smoothly.

Finishing With Fabric

Choose a durable cover fabric that suits the room. A tight weave stands up to frequent sitting. Look for fade resistance if your nook gets strong sun, and consider a washable or removable cover for easy care.
