Series 1 Chair by Steelcase

Features:

• Integrated Liveback Technology with Adjustable Lumbar Support Allows the chairback to change shape and mimics the user's spine as it moves throughout the day. Contours to fit a user's spine through a system of flexors tucked neatly inside the backrest, offering continuous lower-back support as you move in your chair.
• 4D Adjustable ArmsMove in height, width and depth, and pivot to better support the user's neck and shoulders. The cantilevered arm design encourages postural change.
• Adaptive BolsteringAdaptive bolstering in the seat cushion creates a custom comfort pocket. The seat foam is cored (small cylinders are cut out of it) to allow for more compression in some areas of the seat than others. This allows the Series 1 Chair's foam seat to adapt to your unique size and shape.
• Weight Activated MechanismAllows for quick, intuitive seat adjustments.
• Allows the seat to be positioned forward or backward for long-term comfort.
