We got these to replace similar chairs we bought over 10 years ago.  The mesh fabric holds up very well in the Florida sun.  Our chairs are on the patio of our RV and get as much use as our living room furniture.  They spend 5 months in Florida and 7 months on our deck in Ohio.  They are very comfortable for both my wife at 100 lb. and me at 6' and 180 lb.  They are not the oversize chairs.  They have a comfortable angle to the back, but not too far back to use at the table.  In Florida we appreciate that no metal can touch skin even wearing a bathing suit.  And the fabric doesn't hold moisture.  Even wet with dew they can't hold much water.  They are our favorite folding chair, even better than most of the non-folding chairs.  Most everyone who visits comment on how comfortable they are.
