Because Windsor back bar stools are typically made from wood, the weight capacity often depends on the quality of the joinery and the wood’s Janka Hardness Rating. However, you can expect a high-quality bar stool to support up to 300 lbs.
For a higher weight capacity look for Winsdor back bar stools made from pressure-treated hardwood, such as cherrywood, maple, or oak. You can also check the manufacturer’s specs for indications of the joins used. Look for joinery terms, like mortise-and-tenon and dovetail, as these offer the greatest strength and stability.
You could also opt for a Windsor back bar stool with a metal base and wooden seat for increased durability. Opt for powder-coated heavy gauge steel to prevent corrosion.
