custom cut foam triangle

A custom cut foam triangle is the secret behind a comfortable reading wedge, a sleek daybed backrest, or a supportive bolster that keeps its shape year after year. Instead of forcing a standard pillow to fit, a triangular foam insert gives you clean angles and steady support exactly where you need it.

Where Triangle Foam Shines

Triangle shapes are surprisingly versatile around the home. Popular projects include:

• Wedge pillows for reading in bed or elevating legs
• Triangle bolsters for window seats, benches, and daybeds
• Floor lounging cushions and kids' play corners
• RV and boat seating backrests

What to Look For

Firmness and Feel

Choose firmer foam for backrests and bolsters that need to hold an angle, and a softer feel for leg rests or casual lounging. Think about how much weight the cushion will carry day to day.

Size and Angle

Measure the space carefully, including height, depth, and length, and consider how steep you want the slope. A gentle angle suits reading, while a taller profile works well as a seat back.

Cover Fabric

Pair your foam wedge cushion with a durable upholstery or outdoor fabric for easy care.
