Kids’ Booster Cushion

Project preview

This video is for members

Join Lulu Ferris to watch the complete class and sew along at your own pace.

What you’ll make

Sew a portable booster cushion that raises a child at a dining chair for meals, drawing, or play. It is intended for children who can already sit independently.

Adjustable buckle straps fasten around the chair back and beneath the seat. A lightly padded back adds comfort, and the zippered cover can be removed from the foam for washing.

What you’ll learn in this class

Reinforce lightweight fabric with interfacing.
Finish edges with a serger, zigzag, or overcasting stitch.
Sew and turn straps and attach adjustable buckles.
Add batting to the padded back panel.
Install the zipper in the center panel.
Match centers and corners while assembling the cover.
Reinforce the chair-strap attachment points.

Fabric and sewing choices

The sample combines sturdy canvas with poplin. Canvas or another heavyweight fabric is recommended; lighter poplin can be reinforced with interfacing.

Backpack webbing or bias tape can replace sewn fabric straps. Use a serger, zigzag, or an overcasting stitch and foot to finish fraying edges.

Make it your own

For easier cleanup, use waterproof fabric or coat the outer fabric with a suitable waterproofing gel. The zippered cover can be removed for washing.

Personalize the cover with a child’s name or appliqué. The source also suggests making a bag-style cover for storage and transport.

Verified dimensions

The cover is designed for a foam insert measuring 33 × 33 × 8 cm. Custom-cut foam can be ordered to fit these dimensions.

The video class includes a measured PDF for the cushion panels, chair straps, and foam insert.
