I'm in the market for a new mattress and have been trying to assess the online offerings from Koala, Greywing and Ergoflex. I did register on Koala's website and tonight received an email that Koala are celebrating World Sleep Day with a coupon for $100 off the purchase price on their mattresses (expires midnight tomorrow night). Free delivery and 120 trial period too (these are normal).
I have no idea if World Sleep Day is actually a thing though. I'm not going to google it.
It appears you can normally get $50 by just registering your email with. They are also running another promotion at the moment of $50 off + a $25 Coles Myer voucher using the code SLPMYER. This may be good for those who dont want to save a further $25 (get off OZB….)
Still have not decided if I'm going to go with Koala. But $100 off does appear to be more than has been posted on OZB in the past.
thankyou - just ordered one.. will see how it goes.
