I purchased 2 very comfortable Windsor-style chairs at a yard sale and would like to try to find 4 more (exact match) if at all possible. All I know is that the owner said she purchased them years ago at Penneys. What I found out is that Penneys changes the chairs a bit each year so the ones today I noticed are not the same and also not as comfortable. Any suggestions where I might look?

That is just because I am an antique Dave. The 50's were my teenage years on the farm. Folks who preferred white corn had no hybrid choice until Silver Queen was introduced in 1960. White corn dominated the Sweet corn market until the introduction of Burpee's Golden Bantam in the early 20's. Yellows took off as there many efforts to improve on the original including some hybrids introduced in the 30's. The old op's ( 19th century varieties) were popular until Silver Queen started a new era. They are antique old commercial varieties Stowell's Evergreen, Country Gentleman/Shoepeg, Black Mexican ( my mother's favorite), Howling Mob. Robson Farms introduced a long line of Seneca series sweet corn starting in the 30's and they were good but all yellows

I think the first of your lazy susan solutions would be easiest. The second looks like you would need a second, maybe wooden piece to act as a base. The hardware isn't designed to act as a base on its own. If you purchased a wood base--I googled "circular wooden plaque" and you can find them at craft stores--I think the end result could look nicer than the first option If you are okay with wooden legs for the cheese tray, you could easily cut a fat dowel to appropriate lengths.

These are called Windsor Chairs and you can find them almost anywhere. Many come in fun paint colors, too. They come in a round-back style, too. Here's the one from Maine Cottage.
