Very stiff; the arm rests are a lot lower than they seem and are a bit awkward. It's difficult to assemble, as there are no holes or any markings as to where the holes for the legs need to go, so it's very easy to drill in misaligned leg stands. Also, the sliders for the side back side pieces don't fit with each other. Our solution was to just awkwardly hook them on, so if anyone touches them they fall off, but that was the best we could do. It does however look very nice and modern.
