This one is actually advertised on Milan Direct - who are in fact very similar to Officeworks in that they are not a commercial furniture specialist. Rather they are a big furniture company (Officeworks is an office supplies specialist) who use their buying power to get extremely cheap rates from Chinese factories. They then flood the Australian market with these cheap chairs and sell to people & businesses who want a "affordable" and value solution.
The problem is, as the saying goes, you get what you pay for. No where is this more evident than in office / boardroom chairs.
Here's why you should avoid these IKEA, Milan Direct or Officeworks boardroom /executive chairs.
