Maximum height 83 cm. Folded size between 31 cm (with the ball) and 25 cm (unscrewed kneecap). With removable center tube can even make a mini boom of 25.5 cm. Excellent product guaranteed 10 years of good quality with textile cover for a reasonable price. Ordered Sunday and Tuesday delivered by mail (this is still better than a private carrier when you live in !!! campaign), bravo Amazon.
