Really pleased with my replacement chrome gas stem. Arrived within 2 days of ordering and the 9inch stem is perfect to fix my (very expensive) ergonomic chair at a fraction of the price quoted by its manufacturer
I’m 5ft 4 so this height is perfect for me. I could probably have gone for the 7inch stem but this one means my taller partner can also use the chair.
Would highly recommend Bimi and this product. So easy to install
