Last year I bought a
chair for my office. It is classic style with a high back and five caster
type wheels. The chair sits on a large plastic pad so the wheels easily
roll. One by one every one of the original casters has broken. I
bought a set of five replacement wheels and over the course of about 3 months I
had to replace every one of the original casters with the replacement wheels.
The replacement wheels have
held up nicely and none of them has broken yet. As expected, the chair and the
wheels were all made in China. Another Bad Chinese product. The replacement
wheels were made in the US. Even a heavy person, weighing say 250 pounds would
have his or her weight divided among the 5 wheels. There is no excuse for this
kind of inferior product.
