I bought a couple this year that had arm rests and shooting rails, but no back support. The stand seems nice, and the tree trunk seems to work well for back support, but I did notice that my suit will make noise rubbing on the bark of the tree. One tree causes a lot more noise than the other. I didn't think about this happening when I bought them. I will either wrap a fleece blanket around the tree next season, or bungee a piece of foam around the trunk.
