Get a Perfect Fit With Custom Cut Foam Corner Pieces

A custom cut foam corner cushion is the secret to a sectional, banquette, or window seat that looks tailored instead of patched together. Corner seats rarely match standard rectangles, so foam cut to your exact angles fills the space cleanly, supports evenly, and keeps your fabric covers smooth and wrinkle-free.

Where Corner Foam Works Best

• Sectional sofas: Replace a flattened corner seat so it matches the rest of the set.
• Kitchen banquettes: Fill L-shaped bench seating for comfortable everyday dining.
• Window nooks and boat seating: Shape foam to odd angles and tight built-ins.

What to Look For

Start by measuring each side of the corner, including any angled or curved edges, and note the thickness you need. Consider firmness: firmer foam holds its shape on heavily used seats, while softer foam feels plush for lounging. For outdoor or damp areas, choose foam designed to drain and dry quickly. Adding a layer of batting before upholstering helps soften edges and fill out your cover.
