The tall back of the Mica High Back Office Chair provides greater support to relieve tension in the lower back and prevent long-term strain. The contoured seat with waterfall edge dissipates pressure points and improves circulation while the tilt lock and adjustment mechanism allows for a comfortable rocking or reclining motion. It is upholstered in white LeatherSoft with a chromed steel frame and base. LeatherSoft is leather and polyurethane for added softness and durability. Dual wheel casters provide mobility and this modern executive office chair has a swiveling height adjustable seat.
