The Huku Balance Boards are 100% Irish and are hand made from Baltic Birch plywood, where several layers are glued in a former to create a strong platform. The deck measures 770mm long by 340mm wide which gives a stable platform for all sorts of tricks and exercises. The wooden rollers are hand turned on a wood lathe and finished to the same exacting high standards, and measure 140mm in diameter by 370mm wide. The Huku balance board improves balance, fitness, especially core strength, equilibrium, co-ordination, and reaction time. They are perfect for athletes (especially those in love with a board) kids, or those looking for a new way to work out.
