Work Smart Mid-Back Multi-Funtion Ergonomic Office Chair

Sarah from Devils Lake, ND– Verified Buyer

The chair was easy to assemble and came with all of the parts. I would recommend the chair to someone who is tall. Anyone needing lower lumber support will not find it in this chair. The adjustments on the chair all work except for the height adjustment lever. It was my fault for not paying attention to the full details of the chair functions. It clearly says in the title that the chair is for the mid back rather than the lower back. Overall I think the chair is comfortable.
