Fabulous comfortable chair at a great price. We bought two of these for myself and my wife when they were on sale during the holidays to replace unsuitable chairs that had been pressed into daily duty owing to professional Zoom commitments imposed by Covid. We didn't realize how horrible an non-ergonomic those office chairs were until we tried this Union & Scale chair. Easy to assemble with a functional side bar that allows you to raise/lower the seat height to fit under your desk. You can leave the chair arms off or install them if you prefer arm support (not all office chairs have this feature). The height control on this chair also allows you to recline the chair or lock it in an upright position very handy! The rollers are smooth and do not mar our hardwood floors even without a chair pad in place. Comes in three color choices we selected blue and black. The fabric and cushioning has held up well so far. Couldn't be more pleased with this purchase. Next time we need another desk chair this will be the one.
