I purchased 4 of these. Excellent products. No issues. Packed perfect. Perfect. A++
Finally found a chair that fits my needs to a tee. Although not used as it originally was meant to be used for, it was exactly what I needed. It fits in my space and is so very comfortable. My legs and back are in their correct position and they don't hurt any more. And the price was so good. Thank you.
I looked everywhere for this stool at a reasonable price. Nothing comparable on ebay or Amazon. OpticsInc. had the best price and fast shipping. The stool works great.
Fast delivery. As advertised and at a great price. Will definitely order again.
