ErgoTask seating combines the support of a high-back chair with the user-mobility of a mid-back chair. The tapered back give outstanding lumbar and thoracic support without the bulkiness of a traditional high back. The sculpted high-resilience foam seat cushion, contoured back cushion, and multiple adjustability (nine ways on chair; seven ways on stool) provide a customized fit. Optional sculpted arms adjust vertically and horizontally for better ergonomics.
