It helps me stand at night or early in the morning when I want to go to bathroom. I have osteoarthritis in my left knee. But almost did not buy your product. I went to the store at Laird/Eglinton, in Toronto. I wanted to try out a 2-wheeler walker there but it was in a box. The Sales Assistant was helpful & understood that no one buys something over $100.00 without trying it out in the store!! He was a young man! The chinese lady would not let me try the 2-wheeler walker out!!!!!!! She did not want to take walker out of box!!!!!!!!!!!!! Why? That was mean-spirited and I would never go to that store or recommend it. The same day I went on internet looked up Wellwise and I ordered 2-wheeler using internet. It was $40.00 cheaper!!!!
