Office Hippo are good chairs.
There are plenty of office refurbs for sale. As I mentioned earlier have a look at a site called 2ndhnd. Humanscale, Herman and Steel case are all excellent manufacturers.
I bought an office hippo ages back for about £200. You can sit on that for hours. The chairs you mentioned are you're best bet if you want this style. Almost bought one myself. These will probably have rickety arms and the material will wear quickly. Would look at paying about £75 to £90 if I was going cheap. This is too much for a cheapo brand. The one morty linked on amazon is better value.
Agree but some of these chairs at work cost a fortune £1000 plus and nobody will pay that much for a home office chair or gaming chair unless minted. Would love a Herman Miller but alas not going to happen. Secret Labs or Noble seem a lot better than these no name Chinese identikit chair on Amazon etc.
(lol) (lol) (lol) , no. Rubbish 'gaming' crap. Wouldn't get past health & safety in a proper office environment
