We were most interested in this chaise lounge because we wanted something which is unlikely to rust.  There was no description of the construction.  It looked like this was a fully plastic chair but we found on delivery that the support to change the back position is metal and painted and since there is solder apparent under the paint, only time will tell if we will have problems with rusting, something we had hoped to avoid.  A second inconvenience is that to obtain a full flat position, the slider caps that you need to open at initial setup to place the back support into the track for adjustment positions must be opened and the support removed outside the track.  Otherwise the quality of the frame and the fabric used is excellent.  Comfort is greatly improved with use of a cushion which is not provided.
