Posture and Flexibility with Classic CoreChair
Watch how the CoreChair Classic promotes healthy active sitting with its thoughtfully designed ergonomic features. This video showcases the chair’s ability to enhance posture, support core stability, and encourage gentle movement — delivering all-day comfort and flexibility for both office and home settings.
Improve Focus and Well-Being with the Classic CoreChair
The Classic CoreChair is a premium ergonomic active-sitting chair designed to encourage movement while providing exceptional support and comfort throughout the day. Its individually adjustable, patented motion-resistant mechanism allows smooth, controlled movement in all directions, helping to improve posture, mobilise joints, stimulate circulation, and strengthen core muscles.
The sculpted seat is expertly designed to optimise pressure distribution, prevent sliding, and ensure long-lasting comfort, even during extended periods of sitting. The durable 3D knit stretch fabric cover features a special traction surface, enhancing stability and support.
The ergonomic backrest works in harmony with the seat cushion to embrace the pelvis, stabilising it to promote ideal spinal alignment and balance. This natural support encourages an upright posture, reducing strain and enhancing overall well-being. The patented mechanism also offers adjustable resistance, allowing users to control the degree of movement – ideal for engaging the core and improving mobility.
Designed by Patrick Harrison, the Classic CoreChair is particularly recommended for individuals with pre-existing back pain or those seeking additional postural support.
The sturdy five-star base features a comfortable footrest, and the seat height is adjustable with two ranges: 43cm–49cm (for users 5'7" and below) and 47cm–57cm (for users 5'7" and above). It comfortably accommodates individuals 1.50m–2.00m tall.
Castor options for hard and soft flooring ensure smooth movement in any workspace. The chair exceeds BIFMA/ANSI durability and safety standards and is NEAT certified by the Mayo Clinic for promoting active sitting and increased calorie burn.
Backed by an 8-year warranty, the Classic CoreChair is a long-term investment in health, comfort, and workplace well-being.
