This is a great chair for back problems and it was simple to put together. Highly recommend for in-office use or home office. Rolls smooth on carpet too!
As long as I wear long pants or cover the seat so the mesh doesn't bite my thighs this is a comfy chair. Rolls well on a hard surface. Nice color better than basic black or the 'grey' which actually looked white in the store.
Chair needs to be assembled (unless you want to pay for assembly) but the process is pretty easy. No special tools required -- allen wrench provided. Probably want to have an extra pair of hands to help hold things. Everything fit great. Comfortable chair to sit in. No issues or complaints.
