I'm very pleased with my Union & Scale FlexFit Dexley Mesh Task Chair. My husband put it together -- so I can't comment on how easy that was -- but the chair looks great and I've adjusted it so that it is very comfortable to sit in. Easy to change height and angles. The mesh seat is far more comfortable than I expected. Stylish looking. Another plus is that the arms are adjustable front to back so I can pull all the way up to my desk without the arms hitting. I'd recommend to other buyers.
At time of purchase the seat felt comfy. After sitting in it for a couple of 8 hr. days my rear aches. The 2.5 inch molded tabs under the mesh on each side of the seat frame puts pressure on the top of my legs. This pressure becomes painful. In case you wondering my weight is 204 lbs.. Due to these tabs I do not recommend this chair.
Only had it a couple weeks but so far so good. Bought it to replace one where the cylinder lost gas and you'd wind up on the floor. Use it every day for home office.
