The Z22 upright walker has been designed for individuals who need assistance walking and do not want to lose their independence. The surface of its patented gel shock-absorbing armrests are covered with anti-slip particles, which significantly reduces the impact on the arm joints when pushing; the flip armrest design eliminates the problem of seat width interference and ensures comfort when changing sitting positions. The 8" PVC all-terrain tires feature a deep tread texture to provide stable grip on complex terrains such as slippery roads and gravel, reducing the risk of tipping.
