Abstract
A chair comprises a leaf spring for biasing a seat towards the substantially horizontal position and an adjustment mechanism comprises a front and rear support configured to adjust a force curve of the leaf spring. The front support to enable (a) the front end portion of the leaf spring to deflect upwardly for relieving at least a portion of an increase in a spring reaction force induced by downward movement of the rear support as the seat moves in the rearward tilting direction through a range of rearwardly tilted positions, and (b) the front support to deflect the front end portion of the leaf spring downwardly for restoring at least a portion of a decrease in the spring reaction force induced by upward movement of the rear support as the seat moves in the forward tilting direction through the range of rearward tilted positions.
