The chair I received does not have a center tilt and lock feature. It has the lever (which says "luck" instead of "lock") but the lever does not function. I contacted Wayfair about the issue and they promptly sent me another chair, but the replacement chair doesn't tilt either. I double checked the description of the chair and it is suppose to center tilt, which is further verified by the extra lever on the chair. I'm disappointed, as this is a feature I frequently use. On another note, the material and look of the chair is great! So if you don't care about the tilt feature, this chair is for you!
