The Rock & Roll Headrest Hardware has been enhanced! The crescent-shaped piece is now longer, allowing for greater anterior positioning. Both the removable & the flip-down models are reinforced with two bolts at each knuckle joint. Many of the low-profile headrests in the industry today tend to slip over time. With this “double bolt” protection, Freedom Designs guarantees against any slippage. Both headrests are attached with tracks that do not require t-nuts. This, in turn, allows for an infinite initial set. The removable non-flip down has a new quick-release mechanism that is designed to prevent rotation as well as make it easier to remove & re-engage.
