attwoodmarine.com SEATING SYSTEMS & PEDESTALS 185 Universal Factors Contouring • The seat’s backrest follows the natural curve of the spine • An upward curve at the back of the seat pan rotates the pelvis forward and properly positions the lumbar region • A rounded front (“waterfall”) edge reduces pressure on the thighs Backrest Angle • The seat relieves pressure by shifting upper body weight to the backrest, while not reducing support. This is done by angling the seat and seat mount • Optimal seat pan-to-backrest angle is 95° -105° for passengers, 95° - 100° for drivers Seat Height • Pedestal height is critical for comfort and driver’s vision. If too low: weight shifts onto the sitting bones. If too high: weight shifts onto back of the thighs and into the spine • Seat height should be adjustable within a 5" range — 14-1/2" to 19-1/2" above the deck Proper Dimensions • Seats should fit a range of body sizes • Attwood’s seats accommodate body frames ranging from small (5th percentile female) to large (95th percentile male) Dynamic Comfort Underway While underway, both SAS suspension types absorb up to 4Gs of impact from waves and hull pounding. Static Comfort for Relaxing Even while idle and sitting still, the SAS suspension adjusts to pressure and adds long term comfort. Specialized Factors Shock Absorption • Attwood was the first to create effective shock absorption that isolates the boater's spine from hull pounding. Attwood accomplishes this through our two revolutionary seating suspension systems. Both take a 4G hit without transferring shock to the rider by providing 3-inches of travel for a soft landing without bottoming out. Cushioning • On Attwood seats, the right amount of sculpted foam enhances the comfort and support already designed into the ergonomic contour • If foam is too thick, the body “swims” without support, and movement is restricted • If the foam is soft or thin, it “bottoms out,” leading to discomfort or injury Breathability • Venture folding fishing seats have ventilated seat back and pan to allow pass-through of air and water for increased comfort Accessories • A flip-up bolster can add height and improve the field of vision for maneuvering The Factors of Seating Comfort What makes a seat comfortable? The answer becomes complex as boating becomes more specialized and boaters more sophisticated. As your seating expert, Attwood stays ahead of design trends. In the columns below we list the universal and specialized comfort factors you should look for in any seat you choose. With Suspension Impact is absorbed by the suspension — not the boater. Without Suspension Repeated impact can cause pain and chronic disk injury. Conventional Seat Graphs show that conventional seats allow pressure points and impaired circulation around sharp "sitting bones". Seat with Suspension The Attwood suspensions have stretching action to minimize pressure points. SAS and 4G Mesh SAS Suspensions Provide
