Optimal fit

I have a 15-year-old office swivel chair manufacturer TopStar, who at that time cost 400 DM. Now the gas spring was broken. I on the chair - unlike many of today's office chairs - very good seats, I did not want to just throw it away. The requested from me office furniture dealers could not or would not fix the chair. The manufacturer TopStar could not help, because in the chair no type designation is also attached. Instructions and statements are not been detectable after 15 years. Also consult the manufacturer of the gas spring I got no further, this produces now no gas springs for chairs more.

Finally, I have the gas lift yourself then expanded by means of penetrating oil (WD-40) and hammer and accurately measured. (Instructions can be found on YouTube.) The gas spring of ProNova fits beautifully and has even a greater adjustment than the original gas spring. The delivery was quite fast (2 days after ordering).

The quality impression is good. The low suspension works flawlessly even with heavy people. Total me this gas spring appear rather better than the originally built by TopStar original gas spring.

Now I am very happy that I was able to fix my "precious" Office chair for 28,70 Euro (incl. Shipping) itself. Probably he will serve you well for many years.
