Feeling crafty, but don’t know how to knit? According to My Modern Met, you can create a handmade-looking hat without lifting a needle. Swiss designers Damien Ludi and Colin Peillex created the Rocking Knit, a rocking chair that harnesses kinetic energy in order to make knitted headgear.

Inhabitat reports that Ludi and Peillex designed the dual-purpose glider while studying at the University of Art and Design Lausanne. It looks like your typical rocking chair, but with a twist: The chair’s moving seat is attached to gears in a frame above your head. As you sit and sway, the motion moves the gears, which draw up yarn from a giant spool underneath the seat and feed it into a knitting round. The final product? A bright red beanie—and an ultra-relaxed wearer. Who knew sitting could be so productive?
