Beautiful chair.  Had less than 2 weeks, chair stopped working, appeared to be a short in the electrical system.  Control panel warm to touch, electrical odor.  Unplugged for 24 hours, chair began to work again, USB port does not work.  Wayfair put me in contact with manufacturer.   To date, problem has not been resolved with Manufacturer.   
Wayfair customer service representatives have been wonderful to work with.
