Helmi seating system

Daily seating

The time per day spent seated is significant. Finding and configuring a comfortable and therapeutically correct seating position requires knowledge and skill. There is no substitute for that skill, but the work can be made easier.

The Helmi seating system is extremely easy to adapt even while the child is seated.

All adjustments are ”outside” the seat. This enables a smooth variation of the seating position without having to transfer the child in and out of the chair or removing any upholstery.

The ease of use, combined with a strong structure and reliable functions, make the Helmi seating system a long-term and trustworthy chair for many needs.
