That should be obvious, one would think. When chairs are put up for the cleaning crew, many damage the tabletop, which is frustrating. The C frame in the Flötotto PRO series is equipped with a tabletop guard.

In addition, it has an extremely robust seat shell which allows for ergonomic, 360° sitting. The C frame is available in six sizes in accordance with DIN EN 1729 – from size two to seven. The colour code on the frame makes it easier to match it with the sizes and simplifies variable use at changing locations.

What people who use it say:

“As a teacher, I place value on switching between instruction and group phases during class. We need chairs that support both: Flexibility and (!) concentration. What it noticeable about the PRO
is how straight, actively and dynamically the children sit on the chair, without arching their backs. They intuitively place their elbows on the backrest when the focal point in the room changes. A phenomenon that excites me: when discussing conflicts, we sit in a circle, but backwards on the chair. That way, everyone has a protective shield in front of them. This makes it easier to discuss and solve problems.”

Ingeborg Fröhlich, teacher
