I'm an ergonomics technician at a biological research institute. Some of our more compact scientists were left with their legs dangling when they raised their chairs up to be as close to the bench as possible. I ordered one to be sure that it was sturdy enough and would fit the needs of the scientist who requested it.Delivery was lightning fast which always makes our department look good. It seems sturdy. It fit the scientist's needs exactly. I will be ordering more.I agree with the reviewers who recommend that the company ditched themassage rollers. They do not add value. For one thing scientists are not allowed to take off their shoes in the lab!
