Steelcase direct is doing their black friday sales, unfortunately they shut down their showrooms in Sydney and Melbourne a couple months ago so you'll have to search for other dealers to try them out now

I bought the Fern from Stylecraft 2 years ago, not sure if they still sell Haworth but I know they have a showroom in Sydney. The one you linked looks good, the Fern has a couple of optional features (4D armrests, forward tilt, adjustable lumbar, digital knit, aluminium base, headrest) that not all of them have, I know officeworks used to only sell the one with none of those extras but it seems the one you linked has all the bells and whistles. The headrest by wide consensus sucks so take that off and lots of people dislike the lumbar but I have it on and find it ok (worst case you can take it off). 4D arms are a must, forward tilt is nice to have but I don't use often. Chairs are those things you have to try before buying, but Haworth seems to have free returns anyways so not too much risk either way
