Alera Etros High-Back Mesh Chair

The Alera Etros ALEET4117B is a high-back swivel chair built for office workers who sit for long periods. Its breathable mesh back promotes airflow while the cushioned mesh fabric seat provides consistent support throughout the day.

Adjustable Lumbar and Waterfall Seat

Adjustable lumbar support lets each user tune lower-back pressure to their preference. The waterfall seat edge reduces contact stress behind the knees, helping maintain circulation during extended sessions at a desk.

Swivel Tilt Mechanism Included

The integrated swivel/tilt function allows the seat and back to recline together while the chair rotates freely. This built-in movement supports posture changes without requiring separate levers or add-on accessories.

Questions about this item

Will the Etros ALEET4117B mesh back match the look of my existing black office furniture?

Yes, the chair comes in a black finish with a breathable mesh back and cushioned mesh fabric seat that coordinate with standard black office pieces.

How can I verify the adjustable lumbar support is set correctly after assembly?

Sit fully back; the lumbar curve should contact your lower back without gaps, and the waterfall seat edge should leave a small space behind your knees.

Does the box include a headrest or must I purchase one separately for the ALEET4117B?

The supplied components are the chair frame, mesh back, cushioned seat, adjustable lumbar mechanism, casters and hardware; a headrest is not included and would be a separate purchase.
