The All-Weather Low Back Quick Disconnect Seat Shell has been a durable standard for over 25 years. With its bullet proof design and heavy duty construction, these seats might even outlast your boat. Not just durable, but comfortable and functional as well, the All-Weather features a double contoured seat pan that eliminates pressure points. Stainless Steel hinge pins secure the fold down back and included proprietary Quick Disconnect Mount provides for even more functionality. The QD mount allows the seat to swivel on a low profile corrosion proof disk, and can also be removed for storage or to be used in another location in the boat. The All-Weather QD dimensions (including mount) are 18"H x 18 1/4"W x 17"D.
