The rectangular seat of Etac Smart can be used from different sides. One offers a wider seating area and the other a narrower one. The corners make it easy to straddle the seat for extra stability. The push button lock function makes it easy to both fit and remove the legs. The oval shape prevents the telescopic legs from turning when adjusting the height. To ensure stability, the legs are angled outwards. This means that the higher the seat, the larger the footprint. Responsive, non-slip ferrules adapt to the floor and provide stability on the most uneven of surfaces. 81951010 Stool, standard height, grey Seat: Polypropylene Legs: Aluminium, polyamide Ferrules: TPE Max user weight 200kg Seat area 430 x 380 mm Seat height 420 - 570 mm Weight 3,2 kg Width mm 455 - 465 x 410 - 430
