Balder Junior J340 – Children's Standing Powerchair

From fun in the park to trips to the zoo, a child's life is all about new and stimulating experiences. Being able to play happily and enjoy the company of other children is incredibly important, and this has inspired Baldertech to design a very special powerchair - the Balder Junior 340.

The J340 is much the same as our Balder J335, but with the added function allowing you to stand. When the J340 begins to move to an upright position, the supporting castors will automatically lower when the surface is level, enabling your child to move safely while standing. The 340 Junior will also raise and lower your child as they sit or lie, so they can reach up higher or down closer to the ground. In addition, they can tilt forward and back into positions that make them more comfortable as they play, relax and work.
