Alera ALEIN4811 Interval Swivel Tilt Task Chair Black

Interval Swivel Tilt Task Chair

The Alera ALEIN4811 is a black task chair built for general office work. Its molded plastic shell resists impact while a waterfall seat edge reduces pressure on the underside of the legs. A five-star base with casters provides smooth mobility across the floor. The chair ships as a single unit.

Adjustable back height for task workers

Workers who need pneumatic seat height adjustment and back height adjustability will find the core ergonomic controls covered. Buyers who require integrated armrests should look elsewhere because arms are sold separately. The 100 percent acrylic tone-on-tone pattern suits professional environments but offers no mesh or fabric breathability options.

Armless configuration sold separately

The single specification that decides fit is the absence of included arms, with optional arms available as a separate purchase. This determines whether the chair matches a workstation that requires immediate arm support or one that allows a later upgrade. Verify the separate arm SKU before ordering to complete the setup.
