Something about base chair

The chair may also include a support in the form of a pedestal coupled to the base. A yoke may be coupled to the pedestal, with the seat assembly coupled to the yoke and adapted for pivotal movement and for vertical adjustment with respect to the base.
As has been noted, such known arrangements for nestable and folding base chair are intended to provide for compact storage and space savings, and may generally achieve that purpose. However, these known arrangements typically achieve compact storage and space savings only at the sacrifice of overall functionality, i.e. comfort, adjustability, ease of use, transportability, etc. Moreover, these known arrangements for nestable and folding chairs by their very nature also tend to limit aesthetic design possibilities.
