Four-wheeled walker stable and safe for the user.
Large wheels allow you to easily overcome unevenness of the ground, i.e. Curbs. The placed shelf for sitting allows you to rest at any time of the walk without having to look for a bench.
An additional advantage of the balcony is a shopping basket and a tray for transporting things.
Ergonomic handle ensures comfort of using the walker. Adjustment to the user is done by adjusting the height of the handles.
