Task: Design a chair for a person with severe muscle disorder

Year: 2009

 

Music fills our everyday life and to be able to practise it is something most people take for granted.

The user of the ”chair”, a boy with a severe muscle disorder, would like to be able to play the piano for extended periods of time without feeling pain or discomfort.

A few guidelines where given from the boy and his family: 

  • The piano chair for the the boy must be portable since he quarterly participates in concerts.

  • The pressure on the boy’s body should, if doable, be divided on as many pressure points as possible.

  • The “chair” would have to allow for expressive playing and not “lock” the shoulder or arm in a way that would hinder the ways of playing. 

The current solution, leaning on a kick scooter and hanging over the handles puts the pressure on his armpits. This solution makes playing the piano possible but causes severe discomfort when playing for a long time.

The materials in the end product where chosen, mainly on the criteria’s to work technically and to keep a low weight and give stability and comfort.

The piano chair consists of a frame of aluminium tubing, with several folding and adjustment settings.  

The cushion that the boy’s body rests against is made in one piece from a body cast and covered in leather. This gives friction and although the chair looks a bit odd a more of a classic appearance to it.
