It is a shame there is no local australian sources for a good binocular
mount/chair. They can hold big binoculars up to 12 lbs (or 5.5 kg).
I found two US sources in the internet :
1. It is called couch potato telescope binocular chair (US$ 260 without beach chair) plus shipping

2. The other one is called Ez Gazer (US$ 350 without the beach chair) plus shipping

It is not that difficult to construct with the kit and using local materials from a local hardware store. But, I am no handyman, and the shipping cost for a ready made bino chair costs nearly the binocular chair itself. And the low australian dollar doesn't help.
I wish there is someone out there locally who makes such a product.
