The PC recline screw cover kit is necessary for Human Touch Perfect Chairs that fall under the Perfect Chair recall notice. If you own a power-recline Perfect Chair, we ask that you take a moment to review the Recall Alert to determine if your Human Touch chair is included in the recall. The Recall Alert has photographs to help you in this regard. If the screw is visible and not fully enclosed (that is, if you can see any of its threads), then your chair is probably included. If your Perfect Chair falls into this category you may order the kit online at no charge. PLEASE NOTE: This accessory is only compatible with wood-based Perfect Chairs and does not work with PC-085, PC-086 and other fully upholstered models.
