This chair is made with a lot of thought, it has reinforced hand rests, and back rests. The mesh is a double weave and is on the entire portion where you back and butt touch, I am sure this will help with the sweating. The arms have a buckle and strap on the back to raise or lower for each individual. It is a light grey and double stictched... I will post pics as soon I get it figured out. (new device) Only one issues some may have if you are really tall you might think this chair is a bit short. Works great for me!
Update on pictures
In the ssrchair #1 (not the advertisment) the strap is buckled on the right but I left the left side undone so you could see it!
Notice the black material where the metal inserts into the material in chair pic #2 the buckle and the strap hook up there and is reinforced! Also on the underside of the hand grip area of the armrest.(pic #3)
