I have bought "sewing chairs", office chairs, and used a used office chair....by far the best chair is the used chair I bought at an office supply store. It is dusty rose and was replace by a large company because they changed their color. I did pay $100 for it which caused me to scratch my head and wonder about my sanity but the sales rep told my it originally was about $800 yikes! and it has every sort of adjustment you can think of on it. It is very sturdy and stable and comfortable. I used to use it to slide along my concrete floor when doing quilting on my little midarm long arm. still in good shape. The other two chairs not so much....I really need to replace them soon.
