Alera Interval Task Chair

The Alera ALEIN4819 Interval swivel-tilt task chair is built for general office and task work. It features a moulded plastic shell that resists impact and a waterfall seat edge designed to relieve pressure on the underside of the legs. The chair ships without arms, which are available as a separate purchase. Pneumatic seat-height adjustment lets each user set their preferred working height quickly.

Thermals Noise Power

As a non-powered mechanical chair, the Alera ALEIN4819 produces no operational noise and draws no electrical power. Thermals are not a factor because there are no electronic components or motors to generate heat. The five-star base with casters rolls quietly across hard floors or low-pile carpet without fan or pump sounds. Maintenance is limited to occasional caster cleaning and bolt checks.

Build Fit Requirements

The chair fits standard office desks and workstations thanks to its pneumatic height range and five-star caster base. No arms are included, freeing up lateral space for close desk access or the addition of separately sold arm kits. The impact-resistant plastic shell and waterfall seat suit high-traffic shared environments. Buyers needing integrated armrests, a headrest, or a mesh back should look at other models.

Questions about this item

How do I attach the optional arms to the Alera ALEIN4819, and which step is often missed?

Bolt the arm brackets to the pre-drilled holes under the seat using the supplied hardware, then tighten all screws evenly; the step people skip is confirming the brackets sit flush before final torque.

What part of the Alera ALEIN4819 will need replacement first with daily use?

The casters on the five-star base wear fastest on hard floors; keep spares handy and swap them when rolling becomes uneven.

What limit appears first on the Alera ALEIN4819 during long sitting sessions?

The molded plastic shell and fixed lumbar contour create a pressure ceiling after several hours, so the seat foam compresses before the pneumatic lift reaches its travel end.
