Symple Stuff Oasis Mesh Office Chair with Headrest

I would have liked it to move a bit higher

The chair is ok - it's labelled "Mirage 11" office chair. The chair was fairly easy to assembly but the levers under the sear do not fit on very well and are quite flimsy - I expect they will fall off after a few weeks. Once you have the chair in position (and not needing to use the levers) it is fine though.
