Wobbel Original Balance Board

The Wobbel is an open-ended toy with a near-religious following, and we get it. It’s a curved plywood board that becomes a bridge, a tunnel, a boat, a slide for cars, a stepping stool, a spaceship. Our test two-year-old put theirs through all eight uses within a single afternoon. Pricey ($150+) but lasts to age 8 and beyond. Made in the Netherlands from FSC-certified beech.
