Terrible design of mechanism.  When ottoman is extended the chair will still tip all the way forward, enough to dump someone out.  It isn't stable.   When our dog or grandchild tries to climb in to sit with you the entire chair flops forward, making the ottoman hit the floor and you have to put your feet on the floor in order to stay in the chair.   We thought it defective but Wayfair says "No."  Our last Wayfair purchase.
