I used to design office spaces and sell commercial furniture. It is all about ergonomics. If the furniture supports the task, you are more productive. Office furniture, like living space furniture, evolves and supports the task...thinking our television set ups over the decades as well as stereo equipment. Sewing furniture is no different. If you can afford to buy the Koala, buy it! I am envious myself but if I was shopping for any sewing furniture, I would want at least a desk that allows for the sewing machine to be recessed to be the same height as the table top. Less strain on shoulders. You will get that with your set up!
Fortunately for me, I found a great sewing desk at a garage sale that fit this purpose and oh boy, what a difference it has made !!! Sure beats my 10$ banquet table with the extension table on the machine....too high! Less strain.
It does not stop be from drooling over Koala,etc tho. It is a long term investment that you will love! Do post pics!!
Congratulations!!
