PRO CHAIR
Plusminus
Children grow. Especially at school, they sometimes surpass themselves. That requires a chair that fits any size. The PRO Plusminus, with a 51 cm seat heigh and a flexible foot rest, simulates the DIN EN 1729 sizes 2, 3, 4 and 5. The height can be easily adjusted with a single hand movement, without tools.
Elementary school classes in particular profit from the flexible chair that grows with the child. So do learning groups that span across several grades. Who else is happy about it? Teachers, because they don’t have to bend down as deeply as before.

What people in practice say about this:
“Whoever is responsible for the procurement of school furniture, like me, knows the problem. Especially in the primary school sector, we are dealing with different chair and table sizes that are in doubt too small or too large. With the PRO Plusminus footrest chair, on the other hand, I’m investing a single chair that always fits.”
And the best thing about it is that our PRO CHAIR Plusminus requires only one table height.
