Specifically designed for high-speed boat applications, our Sea Post® Pacifica Torsion is a premium, marine-quality suspension seat that offers “bottomless” seat comfort at high speeds and in heavy seas.  It features intelligent ergonomic design, elegant contoured styling, a rich feature set, and marine-grade materials.

The Torsion mechanical suspension system includes an easy-turn dial to adjust the dual torsion bar suspension for a level ride for operators weighing anywhere from 110 lbs (50 kg) to 300 lbs (136 kg). Select from the Torsion-380 or Torsion-580 shock-isolating suspensions systems, which provide 3.8" (97 mm) or 5.8" (147 mm) of shock-absorbing ride zone, respectively. Choose between built-in or adjustable lumbar support to reduce back fatigue and increase rider comfort.

Elevate the voyage with additional features available only in the Pacifica Torsion-580: height-adjustable headrest, dual dampers to absorb energy and prevent full compression, and an optional 6-way electric power adjust. The Pacifica Torsion-580 delivers an impressive 85% shock reduction, from 26G to 3.8G.

The rugged internal steel frame and serpentine springs are pre-treated and finished with an E-Coat baked TGIC powder coat. All Sea Post marine products feature this marinized finish to deliver superior protection against corrosion, abrasion, and impact. Each Sea Post seat undergoes 1,000 hours of salt spray testing and is tested and ABS certified to IMO High Speed Code Annex 10.
