Cheap mattress in a box prices, especially good for those in places where local selections are overpriced or limited.
I actually bought one of these last weekend with the 5% off code am waiting for it to arrive so unfortunately I can't comment on quality/experience yet. I will update when I can. From reading online, there doesn't seem to be too much info but mainly happy customers, eg. http://whrl.pl/Re4AbD For the price I reckon it seems like a pretty good thing.
Unfortunately no free shipping for: QLD South East, Northern Territory, QLD Regional, Perth Metro, QLD Far North, WA Regional, SA Regional, Tasmania, WA Remote, PO Box
However, I'm in Darwin and they charged an additional $51 for shipping for a double or $75 for a queen, which I found reasonable. Still came in well under most mattress in a box competitors.
