Do not use it myself, but an elderly lady with leg problems. First of a great idea for the elderly, run walker for itself and when it is difficult simply reinsetzen and can be pushed. The chair is quickly assembled, adjustable in height and unfortunately a bit chunky in Tropic like regular walkers. The older woman thinks he might be a little easier, I is not so noticed, but it will have quite. What strikes uncomfortable, the higher it is pulled out, the more unstable the vehicle in bumpy trails, at least the feeling is present. There is some play in the linkages during the height adjustment at the highest level. Nevertheless, price performance is fine if under 280 or he would be too expensive.
