This is the most amazing walker. The Upwalker by Lifewalker is so comfortable to use and way better for your posture than a regular walker. It has adjustable height arm rests, the brakes lock, comfortable table seat and strong sit to stand handles. This is the larger unit which accommodates users up to 6' 5" and 350lbs. I originally paid $1300 for this unit but am only asking $850. Barely used, in excellent condition. Come give it a try.
