Wipeable upholstery with a padded finish

The seat, backrest and headrest are upholstered in PU synthetic leather, described by STEMA as eco-leather. The seat contains foam with a density of 40 kg/m³. The close-up images show the softly rounded seat edge and stitched upholstery. For routine cleaning, follow the operating instructions and use gentle cleaning products suitable for the upholstery.

Seat depth that adapts to your sitting position

A 5 cm seat slide lets you move the seat forward or backward while keeping the backrest in place. The supplier drawing gives a seat width of 51 cm and a seat depth of 46.5 cm, with the slide range shown separately. Set the depth to support your thighs while leaving space behind your knees.

3D armrests with soft PU pads

Adjust the armrest height through 7 cm, slide the pads forward or backward through 4 cm, and rotate them inward or outward. The pads are 25 cm long. These three adjustments help position your forearms comfortably for keyboard work or a change of posture.

Height-adjustable headrest and shaped backrest

The upholstered headrest moves up and down through 5 cm. The shaped backrest provides integrated lumbar support; its height is fixed. The headrest, seat and armrests can be adjusted independently so you can find a comfortable working position.

Three-position synchro mechanism

The synchro mechanism coordinates the movement of the seat and backrest and can be locked in three positions. Its anti-shock function prevents the backrest from springing forward immediately when the lock is released. The operating manual explains how to adjust the reclining resistance using the control beneath the seat.

Smooth height adjustment and a stable five-star base

The class 4 gas lift adjusts the seat height from 49.5 to 58.5 cm. A nylon five-star base with a 68 cm diameter supports the chair. The soft 60 mm castors are intended for hard floors; the supplier recommends a chair mat where additional floor protection is needed.

Four distinct upholstery and frame combinations

Choose black upholstery with a grey frame (SELLA GF black), grey upholstery with a grey frame (SELLA GF grey), beige upholstery with a black frame (SELLA beige), or black upholstery with a black frame (SELLA black). The gallery includes the front, rear, side, close-up and adjustment views for every version.

Tested upholstery and everyday office use

The supplier’s abrasion report for coated upholstery A-PU 360 records a positive result at an average of 102,400 Martindale cycles. This is an upholstery abrasion test. The operating instructions specify a maximum user weight of 130 kg and use for 8 hours in a 24-hour period. The product cards state a two-year warranty.

Dimensions, delivery and assembly

The overall height shown in the supplier drawing is 117.5–126.5 cm. One chair is supplied in one 86 × 32 × 65 cm carton. Packed weight is 21 kg for the two grey-frame versions and 21.5 kg for the two black-frame versions.
