foam cut to custom size

Ordering foam cut to custom size is the easiest way to get a cushion that fits perfectly the first time, with no wrestling an oversized slab with a bread knife. Whether you're reviving a window seat, replacing a flattened dining chair pad or building a daybed mattress, custom cut foam gives you clean edges and exact dimensions ready for your fabric.

Choosing the Right Foam for Your Project

Not all upholstery foam behaves the same, so match the material to how the piece will be used.

• High density foam holds its shape under daily sitting, making it a strong pick for sofa and bench cushions.
• Softer, lower density foam works well for backrests, headboards and decorative pillows.
• Outdoor cushion foam with an open-cell structure lets water drain and dry quickly on patio furniture.

How to Measure for a Perfect Fit

Length, Width and Thickness

Measure the frame or old cushion at its widest points, and note any angled or rounded corners. For replacement seat cushion foam, many sewists add a little extra to the length and width so the cover looks full and crisp.
