Marine Cooler Boxes (Convertible to Seats) – Insulated Cooler/Seat Combo in Multiple Sizes (25–94 Qt)

Keep your drinks cold and your crew comfortable with these Marine Ultra Cooler Boxes that convert to seats. Each of these coolers is engineered for boating life – robust, weather-proof, and multi-functional. The concept is simple but brilliant: the lid of the cooler is flat and reinforced, ready to serve as a seating surface. By adding a snap-on cushion (available separately), the cooler’s lid becomes a padded seat. This is a great space-saver on boats where every piece of equipment might need to serve double duty. Even without a cushion, the lid is strong enough to sit or stand on, supporting the weight of an adult thanks to its sturdy construction and stainless steel hinge pins.

Superior Insulation: These cooler boxes feature thick insulation in both the walls and lid (often an Ultratherm® or similar high-density foam). They are capable of keeping ice and contents cold for many hours, even in the heat of midday sun. The larger the cooler, the more ice you can pack to extend the cooling duration (smaller sizes might keep ice for a day trip, larger ones for multi-day excursions if properly pre-chilled and kept in the shade). This makes them ideal for storing your catch on a fishing day, keeping beverages chilled for the whole crew, or preserving food during a weekend boat camping trip.

Sizes & Capacities: With six size options, you can pick the perfect cooler for your needs:

• Small (01796-25, ~25 Qt / 24 L): A compact cooler ideal for small boats (3–5 m) or personal use. Great as a step or seat for one person. Fits a 6-pack of large bottles plus ice, or a day’s catch of fish. Convenient for short outings or as a secondary cooler on larger boats.
• Medium (01796-36, ~36 Qt / 34 L): A medium cooler suitable for boats 5–6 m. Provides seating for one adult and holds enough drinks and snacks for a small group. For fishermen, it can store a decent haul of fish on ice.
• Large (01796-48, ~48 Qt / 45 L) & (01796-54, ~54 Qt / ~51 L): These mid-large coolers are excellent for 6–8 m boats. They serve as a sturdy two-person seat (e.g., a bench in a center console or bow) and have ample capacity for food and beverages for a day-long trip or lots of fish on ice. They are popular for center console boats where the cooler often doubles as a forward console seat.
• X-Large (01796-70, ~70 Qt / 66 L): A big cooler for 8–10 m vessels or for those needing serious capacity. This size can hold provisions for a weekend, or act as the main drink cooler at a big family outing. As a seat, it’s spacious – comfortable for two adults side by side. Often used as a helm or leaning seat on small yachts or larger center consoles.
• XX-Large (01796-94, ~94 Qt / ~89 L): The largest option, suitable for large yachts, fishing charters, or base camps. This cooler can handle a multi-day ice retention, storing a big catch or lots of supplies. It can seat two people very comfortably (even three kids). It’s hefty but still portable enough to move on deck or take ashore for a picnic.

Marine Durability: These coolers are built to withstand marine conditions. The plastic (polyethylene) is UV-inhibited so it won’t crack or yellow quickly under sun exposure. All hardware like screws, hinges, latch mechanisms, and the drain plug are made of stainless steel or other non-corroding materials. The drain plug is typically threaded and tethered, allowing you to easily drain melted ice water overboard without having to tip the cooler. Rubber gasket seals in the lid help maintain the cold and also prevent water sloshing out when underway. The exterior surfaces are smooth and easy to wipe down, while the interior liners are food-safe and odor-resistant.

Comfort and Convenience: When used as a seat, especially with a cushion, these cooler tops are quite comfortable. Many boaters place them in the cockpit or bow as additional seating for guests. The cushion (if applied) usually snaps on and off for cleaning. Even without it, the surface has molded tread or non-slip texture, making it safe to stand on (some use the cooler as a casting platform when fishing). The integrated fish ruler on the lid (marked in centimeters and/or inches) is a bonus for anglers – measure your catch immediately and know if it’s a keeper. Side handles (either swing-up handles or molded grips) make it easier to carry the cooler, and they’re designed to support the weight when loaded.

Why choose a cooler/seat combo? On smaller boats, space is at a premium. Having an item that can keep your drinks cold and also provide a place to sit is extremely valuable. It reduces clutter and ensures nothing on board is single-purpose. Plus, marine cooler-seats are cheaper and simpler than installing a dedicated fridge or additional seating. If you have a fishing boat, it’s practically essential – it keeps the deck clear (fish go straight into the cold box) and friends can sit on the cooler while waiting for the next bite. For pontoon boats or bowriders, a cooler seat can be an extra bench. For camping or tailgating, take it out of the boat and you have an insulated food storage and an extra stool around the campfire.

In summary, these marine cooler boxes with seat-convertible lids are a smart investment for any boater or outdoor enthusiast looking to maximize utility. They are built tough for marine use, keep cold for long periods, and can be comfortably used as seating. Choose the size that fits your boat and never be without a cold drink or a spare seat on your adventures.
