DON'T FORGET FREESHIP:
Just bought the 2 chairs in the title plus a Bella Vita lumbar/back support for use with any chair. My total was 307 after using the free shipping code.
I think most/all of these chairs note ready for dispatch in 1-2 days, and should take up to 4 days to deliver to metro areas - that works out to up-to 6 business days for me in south west Sydney.
Hope this helps someone else out there with a stupid lower back!
Does anyone have experience with the quality of Kogan chairs?
