Ergo Elite Chair is engineered with your total comfort in mind. Aesthetics, form and function are merged seamlessly in a single design, allowing the chair to be minutely adjusted to achieve unrivaled, ergonomic fine-tuning. Tilt tension control with tilt lock allows you to adjust the recline rate based on your weight. Back-angle adjustment sets the back angle for personalized comfort in a reclined position. Synchro-tilt allows the back to recline in a preset ratio to the seat. Seat-height adjustment allows you to set the height to the desired position relative to the floor. Waterfall seat slopes to reduce pressure on the back of your knees for extra comfort through prolonged periods. Back-height adjustment allows the backrest to easily adjust relative to the seat for personalized lumbar region support and comfort. The arms are both depth-adjustable and height-adjustable for proper ergonomic positioning.
