I used to believe that a chair is a chair. Boy, was I wrong? I tried a mesh chair that was nowhere near the same quality as this Herman Miller Aeron chair and I could tell the difference right away. When it was time for me to buy a new office chair, I decided to test one of the cheaper brands that make mesh-back chairs. When I sat in the chairs, I felt like I was going to fall right through the mesh. Herman Miller just offers a support like no other chair. I'll never use anything but a Herman Miller chair ever again.
