I have tried everything and can not get the chair to stay UP in the highest height position. Chair looks great so am keeping. Going to drill a hole thru the metal tube and put a cotter pin thru to keep it up in the highest height. Easy to assemble just takes a bit of time. To much hassle to return it for another.
I wanted a chair that is firm but not huge (like my last chair). This is firm but comfortable was easy to assemble and looks like it will last a long time.
The desk chair exceeded expectations. Easy assembly and good quality really like the color and comfort and able to change height to accommodate desk. I would highly recommend the Tervina Luxura mid-back Manager chair.
After assembling the chair I discovered the gas lift mechanism is defective. When I sit on the chair it lowers by 1-2 inches. Otherwise the chair is pretty nice. Will be returning it.
