The Enova Sparta 3, model ESP3-003A, is a black task chair built to the BIFMA furniture standard with a rated seat load capacity of 136kg. Its defining component is an Italian Donati chassis, paired with TPE lumbar support, 4D armrests and a foldable footrest. This is a chair specified around its mechanism rather than around its upholstery.

The chassis is an Italian Donati unit offering six levels of tension control. Tension governs how much effort it takes to push the backrest away from you, and six steps is enough to suit a light frame and a heavy one from the same chair. Donati is a specialist furniture mechanism manufacturer rather than a generic component, which is why it is named.

The tilt locks at four separate positions, so you can fix an upright angle for keyboard work, a slight lean for calls and a deeper recline for reading. Locking matters because an unlocked tilt makes you brace continuously against the backrest, which is tiring in a way most people never trace back to the chair.

A seat slider is built into the chassis, letting you move the seat pan forward or back to match your leg length. Correct seat depth leaves a small gap between the front edge and the back of your knees. Get it wrong and the edge either digs in behind the knee or leaves your thighs unsupported for the whole day.

Lumbar support is moulded from TPE in black, a flexible material that gives under load rather than presenting a hard shelf against your spine. Flexibility is the point: a rigid lumbar block supports one posture, while a flexible one keeps contact as you shift between leaning forward at the keyboard and sitting back to think.

The lumbar support adjusts vertically as well as flexing, so the contact point can be raised or lowered to meet the natural curve of your own back. That curve sits at a different height on a tall person than a short one, which is exactly why a fixed lumbar pad works for some people and irritates others.

The headrest moves on two axes, so both its height and its angle can be set rather than only sliding up and down. Neck support that meets the head at the wrong angle pushes the chin forward, which causes more strain than no headrest at all. Two axes of movement is what lets it sit correctly for different sitting heights.

The armrests adjust in four directions and carry PU pads on their upper surfaces. Height, width, depth and pivot all move independently, which is what lets the armrest carry your forearm at desk height instead of forcing your shoulders up. PU keeps the top surface soft against bare arms through a long summer day.

The Sparta 3 uses a foam seat rather than a mesh panel, giving a cushioned surface with more give underneath you. Foam suits anyone who finds mesh too firm across the sit bones over a long stretch, and it holds an even surface under a laptop bag or an elbow when you turn sideways to talk to someone.

Height adjustment runs on a Korean KGS class 4 gas lift in the 100/70 size, finished in black. Class 4 is the top tier of the common gas lift ratings, and the 100/70 size gives this chair a longer travel range than the shorter cylinders used on entry-level models. The cylinder is what decides whether a chair holds height or sinks.

The chair stands on a black nylon base. Nylon is the standard material for a five-star chair base because it combines the necessary strength with a small amount of flex, which absorbs shock rather than transmitting every movement straight up the column. Its black finish matches the frame and upholstery.

The chair rolls on 60mm casters with black PU treads. PU is the softer of the two common caster materials, which makes it markedly quieter than nylon on a hard floor and far less likely to scuff laminate or wood. At 60mm they are also large enough to climb a rug edge without needing a shove.

A foldable footrest is built in under the seat and pulls out when you want to put your feet up between tasks. Because it folds fully away, the chair keeps a normal footprint when you push it under a desk. It is the feature that turns a task chair into somewhere you can take a fifteen minute break without leaving.

The Sparta 3 is built to the BIFMA standard with a rated seat load capacity of 136kg. Net weight is 19.67kg and gross weight is 22.27kg in a carton measuring 830 x 350 x 640mm. That is a slim box for a chair of this size, which makes it easier to get up a narrow staircase.
