Abstract:
An adjustable armrest having a base and an armrest that are coupled together through an articulating joint assembly. The joint assembly includes a body with a first articulating ball joint and a second articulating ball joint. The first articulating ball joint is coupled to the armrest with the second articulating ball joint being coupled to the base.
Abstract:
A chair base assembly including a leg assembly, a seat support and a support column coupling the leg assembly to the seat support. Either one or both of the seat support and the leg assembly including an insert member that extends about a bore defined within each, configured to accept the support column. Such an insert member includes a winding that is outwardly deformable so as to be outwardly deformable. The insert member may include a winding of a substantially uniform wire-like member having a substantially uniform cross-sectional configuration so as to define a circular cross-section.
