A chair includes a support base, a back and a seat. A tilt mechanism connects the back to the base permitting the back to move from an upright position to a reclined position. A forward portion of the seat is connected to the base through a double pivot. A rearward portion of the seat is connected to the back through a single pivot. As the back tilts to its reclined position, the rearward portion of the seat moves rearwardly and downwardly and the forward portion of the seat moves rearwardly and downwardly lowering overall seat height and eliminating leg lift.
