These lounge chairs are extremely sturdy with backs that recline to any position you would want, including perfectly flat. I love that the frame is a resin plastic, so it will never rust or have a coating that will wear off.  Clean lines and comfortable.  I'm fairly short, at 5'4" and feel like the back should be higher for anyone with a long torso.  The back measures 25" high.  (It's fine for me and my husband who is 5'9".)  High quality fabric.  My only disappointment was that the picture showed the color looking more of a light aqua, which is what I wanted, while in reality they are a very bright turquoise.  I'm hoping the sun may fade them a little, but the fabric may be too high quality to allow that!  I'll get used to the color with time.  Well built and designed lounges.  Wish they came in more colors.
