The following photos will document the attaching of the textile on a prepared chair.
The spring system was already installed in the seating area. The following photo shows the seat ready to apply the textile.

The textile is cut - minding borders and the patern.
The textile has to be attached with some auxiliary nails while streched - always nailing two opposite sites and not sinking the nails totally to correct errors. If the textile is stretched unevenly, the patern is warped on the seating area. 
The auxiliary nails are applied and the even stretch is verified based on the textiles pattern - now the textile can be tacked.
We spare the corners because here the textile has to be applied correctly and fixed with needles before it can be sewed.
The textile is tacked onto the frame and the front corners are sewed, now we can rejoin the parts of the chair.
The bottom side will be screened with a white textile which is sewed to the top textile.
That's how the result looks like.
