Excellent kit of parts, not too hard to assemble and looks good  now finished.  One MAJOR problem  the control system to tilt the seat is locked solid so, as yet, I have only one sitting position .  I had to fit it to complete the assembly.  Fortunately it is fairly comfortable  but I would like some action to free or replace the faulty part as soon as possible.  I would suggest one of your fitters visiting to do the job as it is a manufacturing  fault.
