The Urban M1³ barrier-free was developed to break down barriers in everyday office life without the box seeming like a “special solution”. It fits seamlessly into the modern design of the Urban Line.

Barrier-free access and operation

• Ground-level access: No base, no steps - the wheelchair enters the cabin directly at floor level.

• Access control options: Can be optionally combined with password or face scanning systems for protected work areas.

Transparency to DIN 18040

In order to give you maximum planning security, we are concerned with the dimensions transparent:

• Door lights: approx. 82 cm (The M1³ is therefore wheelchair accessible. For the full DIN standard of 90 cm, please select the L2³ barrier-free).
• Interior: Due to the design The turning area is just under the required 150 cm, but is optimized for standard wheelchairs.

Sound insulation (measured according to the latest ISO 23351-1 standard):

• Plus: 32±3 dB (ISO class A)
  • Maximum discretion for concentrated work and phone calls.

(Important: The switchable "Smart Glass" option automatically includes the best possible plus sound insulation).
