Hello there, Just got my EPIC chair a few days ago and I love it! However there's one little problem that I have and I don't know if it's normal or something I'd have to worry about, would like to know the opinions of fellow OCUK members that have the same chair. When the tilt mechanism is unlocked i can tilt the chair by leaning forward/backward without any issue but when the tilt mechanism is locked I though it wouldn't move at all, but there's movement, very small but when I lean forward/backward I can feel and hear the chair move and making a sound ( when the mechanism reaches the lock point) . Video included , most likely low sound so have to raise the volume. https://www.youtube.com/watch?v=79R_QV2j6iA I did experience this with much older office chair so just want to know if this is normal for this particular model.
