This is a really good buy. It’s very comfortable and provides excellent back/lumbar support. The mesh back is supportive and breathable. The fabric seat is quite squishy and supportive as well. The arm rests are molded and really do a nice job cradling the arms as you type. One star was removed for the slightly rickety feel of the chair back. It wiggles a tiny bit. Also the coasters do not roll smoothly.
