Electric height adjustment, but with a back regulated with gas springs. This is adjusted with one hand, with slight pressure with the other hand. This chair swivels through up to 350°, helping to provide functional comfort and good ergonomics for anyone taking samples. You do not need to change sides when taking samples from the other arm, and the seat can easily be locked in the preferred position using the lever on the side. Note that the frame of the chair has no castors and rests on the floor, in the same way as a swivel chair. This makes rotation extremely smooth.
The armrests are flat and infinitely adjustable with one hand. The calf support moves automatically when the back is moved, and the chair can be moved all the way down to shock position. When upright, the calf support moves right in so that it is not in the way when the patient goes to sit down. The patient knobs also facilitate getting into and out of this chair. The chair is supplied complete, as pictured.
