"SLACK BEAN BAGS". That's where we bought ours. They have all sizes and prices. The guy that owns it is called Felix. The shop is in the industrial part of Aberdeen, easy to find.
we bought a bean bag for our baby at Langham Place in Mongkok... the shop was on the 7,8 or 9th floor... sorry i can't remember exaclty... that place is really confusing....
it cost us $480....
i've attached some photos of it for you to have a look at...it looks like a frog and our boy loves it!
I've got our made in a shop on Lyndhurst Terrace, where you can choose material colour and texture. It's was around $1500, I can't remember exactly! Let me know if need more info. Cyndi
