ONEX GX2 gaming chair, $149 click and collect or shipping available from Officeworks.
Got one from Costco for $160 yesterday (Google automatically alerted me for the Officeworks price drop) it's decent quality I cannot fault it compared to the horrendous Bathurst chair I had been using for work.
Used to have a DxRacer king chair a couple of years ago- faux leather material doesn't feel as nice compared to actual leather, otherwise feels very similar.
Watched/ read a few reviews before biting the bullet- happy with the product for the price.
(Unaware of end date, assume people price matched at Officeworks for Costco- hence the price)
