The All-Weather High Back Seat has been a durable standard for over 20 years. With its bullet proof design and heavy duty construction, these seats might even outlast your boat. Not just durable, but comfortable 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 1/4" x 20 t-nuts allow mounting to any standard marine swivel, slide, or seat spider. The All-Weather Seat Shell will also accept our proprietary Quick Disconnect Mounting Kit for even more functionality. Includes custom fitted cushion, (also available as a replacement item). These cushions feature a wrap around design, 30oz marine grade UV stable vinyl, and high density foam inserts. The High Back All-Weather Combo dimensions are 18 1/2"H x 18 1/4"W x 17"D.
