Solve helps anyone achieve optimal balance and alignment, making it an ideal solution for everybody.Intelligent Design + ReActiv TechnologySmart people deserve smart chairs. Solve is available in three back styles — 4-way stretch mesh, ReActiv and upholstered ReActiv — that provide three levels of comfort and support. For an exceptional level of comfort, the ReActiv back offers a hexagonal pattern that flexes and moves with you to provide a firm fit while keeping the body cool with continuous air flow. Seating options are available with or without arms and feature a waterfall seat contour that doesn’t just look good, but feels good, too.
