Love love these chairs ... hold out to the hot Georgia sun.  Bought two 2 years ago and just bought another and can’t tell the difference from new to older ones.  No fading or sagging or discoloration. I searched long for an aluminum frame because did nt want rust and on decking. 
added protection ... sprayed with scotch guard.  Chair will get light mold dirt on the underside after season but comes off easily with 1 part bleach 1 part water before storing away for winter. Not stackable but legs come off easily for flat storage in shed or garage 
Price and quality is unbeatable. You will not be disappointed if you like this style and want a clause that lasts
