TITANIUM shock mitigation
The Titanium is a series of strong, rigid and durable shock mitigation seat bases with infinitely adjustable suspension, and swivel, slide and height adjustment as options.
A complete system under your boat seat.
According to the product development strategy for the Titanium seat suspension systems, steps have included a several-year-process with attention to:
- Analyzing customer needs
- Different kind of driver ergonomics in boats
- Selection of suitable materials and methods
- Development of optimal compression/rebound profiles
- Testing in different types and sizes of waves
- Testing in different sizes of boats
- Repeated impact- and endurance tests
- Building up an efficient, reliable supply- and manufacturing process
As a result of this process, Scandinavian Seat Suspension Systems (4S) has created a stream-lined product without compromising on the quality in any detail or function.
A reliable product with easy access to adjustment handles and levers while sitting in the seat.
A sturdy product with easily understood and maintained functions – avoiding small and sensitive details/handling (valves, loose parts, tiny adjustment wheels, sensors, etc).
An affordable product making it possible also for private owners of smaller boats to have a comfortable, pain-free ride in whatever sea condition.
The 4S shock mitigation seat base minimizes the risks of pain and permanent injuries from wave impacts, and will make the overall boating experience safer and more enjoyable.
The driver seat should normally NOT be moving when the boat passes small waves and softer sea, as a moving seat affects the ability to feel and maneuver the boat in a safe way.

Shock absorption overview – compiled by SICS (Swedish Institute of Computer Science)
Blue: Impact force on a normal, fixed seat base
Yellow: Impact force with 4S Titanium shock mitigation seat base
The diagram shows a short 2-minute drive in medium rough conditions.
Covering impacts up to between 5 and 6G a few times.
Note that shock absorption efficiency increases the rougher the impacts are.
Tests were carried out with Racefox® accelerometer sensors under seat cushions.
