Take a little time to read our extensive feedback. We are an established spares supplier Herman Miller Aeron's but from time to time cross over onto other chairs. If you like the feedback you see then hopefully we're the spares supplier for you.


The spindles we supply are manufactured by the same company herman miller and many other quality office chair manufacturers use. Cheaper options are available from other sellers but they're cheap for a reason!!


Replacement Gas Lift / Spindle for Human Scale Freedom & Liberty Chairs


The gas lift may also fit some Diffrient World Chairs - on some the gas lift diameter is larger than the top aperture the gas lift slots into on the chair base. 

The (approx) crucial measurements are: The gas lift diameter is 48mm at the bottom where it 1st slots into the chair base widening to 50mm at the point where the gas lift will sit at the top of the chair base.  


 Gas lift measurements - Top of the lift measures 26mm widening to 28mm - this top taper measurement is what most would refer to as standard gas lift fitment size in that it fits 95% of all chairs on the market.


Bottom of the gas lift measures from 47mm and widens to 50mm. 


These are not cheap generic gas lifts. Samhongsa have an annual gas lift turnover of in excess of £90 million and are an official provided to Herman Miller and many other quality brands for their office chairs. 

Please note these are not drop through gas lifts so will sit slightly differently in the base. The internal gas lift workings are exactly the same.

Please note this gas lift will not fit all DIfferent World Chairs due to a change in the base. We believe this to be post 2020 chair althugh if you are unsure please message and we can offer guidance.
