The High-back Navistyle™ Seating System is a perfect blend of ergonomic craftsmanship and smooth functionality. Subtle curves provide lumbar support while the tapered sides allow for the lateral movements desired by active users. The Navistyle™ also features 30 oz UV stable vinyl and our exclusive “no-pinch” hinge, with automatic locking mechanism that secures the seat in the folded position. The High Back Navistyle™ dimensions are 23 1/2" H x 18 1/2” W x 19 1/2" D. All Tempress boat seats will mount to most seat swivels or slides with the built in Stainless Steel T-Nuts, and include Stainless Steel mounting hardware.
