The Oceansouth Boat Seat Boxes with Integrated Waterproof Storage deliver a smart combination of strength, practicality, and style. Built from UV-treated, marine-grade ABS plastic, these seat boxes are engineered to withstand years of exposure to sun, saltwater, and heavy use. Their heavy-duty construction, combined with stainless-steel hardware and a watertight seal, ensures reliable performance while protecting your gear from the elements.

Beyond durability, these seat boxes provide true onboard functionality. The integrated waterproof storage compartment offers a safe, dry space to stow tackle, tools, keys, phones, and safety essentials, while the smooth, clean white finish and subtle tapered design give them a sleek, professional appearance.

Available in two height options to suit different deck layouts, they are designed for easy installation and are compatible with Oceansouth boat seats as well as most other popular seating systems.

Whether used as a primary seating base or as an upgrade to add secure, waterproof storage, Oceansouth’s Boat Seat Boxes are a dependable choice for boat owners who want to maximize space, comfort, and protection on the water.

With their rugged marine-grade construction, integrated watertight storage, and versatile seating compatibility, the Oceansouth Boat Seat Boxes offer boaters the ideal combination of seating comfort and practical storage. Choose either the compact 16″ model or the taller 20″ version—both built to deliver reliability, strength, and convenience for years to come.
