Through a little research on the internet I have an offer of 46, - Euro incl. Shipping Found, which he only 16, - Euro is more expensive than a China product from the hardware store! For the Hazet has storage compartments and solid rubber wheels, no plastic wheel as the normal low stool. Only Ster disadvantage of gas springs could something go further upwards. If one is slightly larger, the legs are otherwise very angled. This could also even more change by exchanging the cartridge, which I will possibly make more. For now it is sufficient, however, and you can finally do minor work in the garage on an ordinary seat!
The stool is indeed designed to 150kg, but I would try this is not quite up to this limit. I myself weigh 85kg, as everything goes, with momentum but one should also not sit on ;-)
