The stool is comfortable, supporting my spine in it’s natural curvier. Thus no more lower back pain. Delivery was prompt. However there was no assembly instructions, which made it difficult to assemble.
It takes a bit of getting used to but over the weeks I’ve found myself using it for more hours each day. I have kyphosis of the spine and it has eliminated all of my back pain. Just my bottom has to get accustomed to sitting on a saddle all day.
