About this Chair

The 4u office chair was built with your comfort in mind, offering an array of ergonomic features and a sleek design that will compliment any office space perfectly.

The ergonomic seat of the 4u office chair is constructed with ergonomic proprietary foam technology. The closed-cell, cold-cured foam is designed to provide body-cradling and balancing support where needed while the softer edges alleviate pressure points for better circulation.

Adjustable back with a 4-position tilt limiter allows you to move while you work.

Height-adjustable arms that move 2-3/4”, allow arm height to be adjusted to your preference.

White frame and groove back create a natural curve for consistent lumbar support and comfort throughout the day.

The groove back is crafted using welded fabric to provide an incredibly comfortable hybrid between a mesh and upholstered back.
