This folding chair is not for long work sessions esp. Not for elderly or sick people suitable-but want very good for party people spend a lot of money and do not do the back convenience. This chair is not very comfortable, because the seat flexes so much by the one spührt the legs of the chair at the rear. The cup holder is made of a fine mesh Thin. On the whole I must say that this chair certainly will not stay long on the whole.
