The latest installment in the TEMPRESS line of marine seating is a rotationally molded Helm Seat that incorporates the patented NaviStyle StylePanel system and ensures superior comfort, unequaled quality, and a wide possibility of styles. Like all TEMPRESS products the Helm Seat is constructed of materials designed to withstand the rigors of the marine environment. By utilizing TEMPRESS StylePanels, the Helm Seat goes beyond the standard snap on upholstery common in the market place today. Additionally, the contoured StylePanels create a comfortable seating surface that is ergonomically correct without the excessive use of foam. Built in lumbar support and a rolled front edge make the TEMPRESS Helm Seat perfect for any boat seat application in which comfort, durability, and superior style are desired.*** If mounting to a standard swivel with 4 holes, this seat requires a reinforcing plate. The Reinforcing plate can be purchased separately under part 57005.WARNING: Cancer and Reproductive Harm -www.P65Warnings.ca.gov
