The bar height of my kitchen counter is an unusually tall 46-1/2". Unfortunately, typical store-bought bar stool are 24 or 29". We have two of the larger stools, but they were not tall enough for our counter. Our counter required 33-1/2" stools. I used White Oak with non-thorugh mortice and tenon joinery. The seat bottom is a piece of 3/4" plywood and the curved back is a White Oak frame sandwiched between two pieces of 1/8" plywood (similar to hollow-core door construction). The seat and back were professionally upholstered with a patio furniture material. I used the design of our existing 29" bar stools but added mortice and tenon joints all around. The upper mortice and tenons overlapped, so half of each intersecting tenon was notched to allow space for its neighbor. The seat and back are removable so that the woodwork can be refinished and the cushions re-upholstered, if necessary. For finish, I used two coats of Zinsser Seal Coat and four coats of General Finish's water-based satin polyurethane. Both finishes have super-fast drying times so I was able to complete that phase in two days. Very pleased with the outcome and stool is rock-solid sturdy.
