Hi Sarel,Thank you for taking the time to share your feedback. We are pleased to hear that the delivery was fast, the chair arrived fully assembled, and that your initial impression of the quality is positive.We are sorry that the free-floating tilt mechanism was not immediately clear. Some chair mechanisms can take a little explanation, especially when the online information does not give enough practical detail.We are glad George was able to make contact with you, explain how the mechanism works, and resolve your question.Thank you for giving us the opportunity to assist. We appreciate your support and wish you many comfortable hours in your new chair.
