Bought a Global Obusforme highback office chair (1260-3) from ABCO, and just picked up today. The chair is excellent. You can adjust it anyway you like, and is very comfortable. I mean extremely comfortable.
People from ABCO are very helpful and nice. We spend 2 hours together to choose the chair that I wanted, explained to me the characteristic of different kinds of fabric, and how to adjust the chair to my comfort patiently.
Price is also great. I did a lot of research and it found it is much cheaper than places like Home Depot and other stores in Toronto. For $440, I got my high back model with Schukra control fully assembled which is excellent. Delivery costs $50 extra, so I just picked up mine to save some money although it is quite heavy.
Since the chair is custom made, it took Global 3 weeks to build which is a bit long. But all in all, it is a great experience to shop at ABCO Scarborough Store! 5 Stars!
