These chairs are great. They stack nicely, the holes in the resin chair surface prevent water and dirt from building up. They are definitely strong enough for my husband, who is a big guy. I got 4 black and 4 olive-the olive is a bit more of a bright/saturated color than I expected, but the color looks great around a table with green trees surrounding. The delivery came when it was supposed to and they were packed well. Highly recommend.
