I would like to say the chair is working great for my mother, also my mother called me said she set in chair and was lowering when she heard a pop and the chair stop working, so my brother went to look for problem, he noticed chair had lowered on wires, so I called Wayfair service line and spoke with an agent that was the nicest and understanding sorry for not remembering her name but she was great. She heard the frustration in my voice and told me I can order another chair so my mind was thinking here we go again I’m going to buy another bad product but she assured me all is ok, she order new chair and it arrived earlier than expected my mother called me and said thank you for the new chair and it’s working great. Thank You Wayfair I would purchase more of your products .
