The OfficeMaster WH96 is an extremely unique chair that was developed as a hybrid of the DB family with models from the Wharton Collection. Featuring the benefits of a foam insert that helps free your shoulder blades from being blocked, the WH96 also offers a more adjustable version of the same "clean-design" control of the Wharton Premier series. What this means is that even on this synchronized knee-tilt model, you have the option of an independent back angle adjustment. Designed to accomodate users up to 300 pounds
