What makes a Windsor Chair Seat Comfortable?
Seat comfort can be regulated by depth and the front/back sloping of the entire seat. The 3/4″ to 1″ depth comment was a good one as this provides enough wiggleroom without the seat feeling like a plank. The F/B seat sloping of 1/2″ or so overall will feel like the seat is saddled more than it actually is. To feel the changes this would make, experiment by placing shims under the front legs. Don’t forget to relieve enough material where the thighs contact the seat. High spots or ridges create pressure points that can cause circulatory problems. Incorrect seat height (too tall) can also be a contributing factor to pressure behind the thighs. Again, play with shims under the feet to see how much to cut off the legs. This does however custom tune a chair to an individual (good for an easy chair or a stand-alone) but would not be practical for a set which different persons would use.
