MIRRA DESIGN ERGONOMIE FAQ

 


 

   
Which Mirra size is right for me?

The mirra comes in one size, that is designed to fit at least 95% of the human population.

 



   
What are the exact dimension of the Mirra?

 



   
What is the difference between upholstered and non-upholstered TriFlex Polymer Back?

The TriFlex™ back is Mirra’s one-piece moulded polymer backrest. It is generous in size to support the users entire back. Pliable and elastic, the TriFlex™ back has geometric shapes and spine construction that create flex zones in the cervical, thoracic, lumbar and sacral regions. This allows the back to automatically adjust to the users size, posture and movements. No manual back-height adjustment is needed. The back also provides aeration.

The upholstered version supplements the polymer backrest with a fabric cover.

 



   
Do I need hard floor casters?

If you have parquet, tiles, laminat or any other kind of hard floor, it is urgently recommended to order hard floor casters. You will profit from the following advantages:

+ less abrasion on your floor

+ lower noise when rolling

+ casters have a break which releases when you sit on the chair, no unwanted rolling around

 



   
Are there further options to configure my Mirra?
