Keep in mind all staples chairs have mechanisms rated to 114kg including chair. If you are heavier person, above 90-95kg after about a year of 6h+ a day use the machanism, rather than the chair, it will get noisy and then fail either due to broken welding around column or by developing slack at the top of the column and permanently leaning to one side. Other than that - great chair (purely because of the material used).
Had about 5 of their chairs in 4 years, including previous generation of the Kashmere, in "sandy" colour. With exception of one set of armrest screws snapped, all of them died because of the cheap, shoddy lifting mechanism. Mechanisms rated to 250kg for US market are available from the same chinese manufacturer for about 10 bucks more but our importers prefer the cheapest ones, because it means higher rotation of chairs - our fatties will keep braking them and then keep buying them. There are few alternatives, EU and Irish importers seem to prefer scissor tilting mechanisms with shorter column in new models, but it will take few years for those to penetrate our local "everyone sells the same 20 chairs with different names" market.
