I have been searching for well over 4 years for an office chair. Quite by accident I found the ergoCentric retail location in Yorkdale. The chair i have purchased is to say the least amazing. The sales representative, Octavio Coloma and the store manager, Mohamad Kuidir were wonderful to work with. They guided me through the introduction to the chair process in a very professional and knowledgeable fashion and i recommend this product line to anyone who spends a great deal of time in an office chair.
