LOVE these!! I wasnt sure at first but went ahead and did it! BOY, I am glad I did! I have a 8 ft long VERY old library table that I use for dining table. Currently the chairs I have are so heavy moving them to vacuum daily is getting old.  So, These looked cute, I loved the shape, and color but I was afraid these would be too flimsy. I WAS WRONG!!
I am 5'7" & 150# and I fit perfectly in these chairs. The kids can actually pick them up and move them too. They are sturdy and easy to put together (just screw in legs). I would say even an average man would be comfortable in these chairs too. However, I would not recommend for wider derrieres because these seats are not that wide.
