Residential-grade bar stools are known to be less resilient and durable than their commercial counterparts. They simply are not designed for restaurant use. For starters, they will hold approximately 250 lbs., where many commercial ones have a 500 lb. weight capacity. Residential-grade stools often do not feature fully welded metal frames, or mortise and tenon joinery, as with commercial stools. Residential stools are also offered with a minimal warranty, if there is one at all. Our range of commercial bar stools comes with the best warranties in the industry. As warranties vary between styles, please contact our customer service representatives for specific warranties.
