Indoor round stool LEITZ Ergo Cosy, Ø 650 mm, height 650 mm, yellow, max load 100 kg

Leitz Ergo Cosy Yellow is a 650 mm diameter indoor round stool/seat designed to promote micro-movements of the back and core muscles, helping to improve posture and reduce back discomfort. Suited for office desks, meeting rooms, classrooms or lounge areas, this compact seat combines the functionality of an exercise ball with the stability of a stool. It inflates quickly and includes a hand pump, two plugs and a durable carry handle for easy transport between rooms. The matt yellow finish and minimalist design integrate smoothly into shared workspaces and flexible seating arrangements.

It is multifunctional — usable as an additional desk chair, a yoga or gym ball for workouts, and for physiotherapy or back stretching.
