Chair does support the lumbar well. The back pops when reclining. A sign the screw arrangement is not sufficient. The seat is slightly wobbly on the pneumatic post. A sign the base assembly is insufficiently sturday for the chair assembly. The mesh is not as thick as I hoped. Overall the chair is of mediocre quality.
Interesting that this chair is now listed at Staples for $20.00 less than I paid within the last two weeks. The chair was very easy to unpack all parts were included easy to follow picture instructions. Everything fit perfectly and the chair was fully assembled within minutes.
