The stool is completely made of painted aluminum, comfortable, sturdy and has an attractive design. However, the processing is more like the cheap no name products from the hardware store (we had an exchange because he has extremely wobbled and the parts were wrong. In addition, a thread and the paint was missing was moderate). The other wobbles also -only not as strong. Due to its low weight, it can be moving or transporting easy. Unfortunately, he does not stack! For permanent weather resistance can not say much, because the furniture is always covered and come down to the basement in the winter. A good, recommendable with limitations branded product. But as I said, the process would have to be much better at this price.
