Designing an armchair in 3D

[Julian78]

Hi, 

I am struggling designing this armchair -not the legs or cushion but mainly the back and side. Does someone has a way of doing this efficiently? 

 

For the cushion I would use subdivision to create the plumpness but for the back, I am totally stuck as there is this curved shape that goes up in the middle.    

 

Any tips would be appreciated!

 

Thanks

Thanks for the detailed process!  I'll give it a bash and see how it goes. The sectioning curve extrude is something I would have never considered.

Cheers
