I have some health issues that will not longer allow me to site at my PC, as a graphic designer that's a nightmare. I was looking for a learning stool which I found the right one to suit my needs. I had problems finding a seller place orders and they were cancelled a week later. Until I came across SmartTeck which saved my life not only did they have the item I needed I received it within days. The leaning stool is great as it's described and nice and steady build. Now I can stand for more then two hours without lower back ache. I thank SmartTeck for service and prompt delivery.
