When you're choosing deck hardware seating covers, the first decision isn't which color or fabric. It's whether you need the support structure or the padding that sits on top of it. The TOONMATE 308436GGRR Pontoon 36-inch Wide Bench Seat Base and the Oceansouth Hinged Type Boat Cushions Bench Seat Length 18-inch x Width 12-inch - Gray sit at opposite ends of that job. One provides a wide structural base for a pontoon bench; the other is a compact cushion that rests on an existing seat. That difference drives everything else.
Quick Verdict
The short answer: these two products are not true rivals. The Toonmate 308436GGRR Pontoon Bench Seat Base is the foundation your cushions sit on, while the Oceansouth Boat Cushion is the cushion itself. Choose the Toonmate when the existing seat base is damaged or missing and you need a new foundation. Choose the Oceansouth when you want a cushioned surface for a smaller bench area and the base structure is already in place.

Where Each Product Wins
Toonmate 308436GGRR wins if you're repairing or replacing the structural part of a pontoon bench. It solves the problem of a missing or damaged base rather than simply padding an existing one.
Oceansouth hinged cushion wins if your bench base is fine and you just need a comfortable place to sit. It's a standalone cushion, so you get the soft surface without having to rebuild anything below it.
Product Notes
TOONMATE 308436GGRR Pontoon 36-inch Wide Bench Seat Base

This is the piece of deck hardware that holds your cushion up. At roughly 36.5 inches wide and 11 inches tall, the base is designed for pontoon seating and includes drainage slots that let water run out the back instead of collecting inside. The recessed toe kick adds a slightly more finished look and leaves space for optional lighting if you want it later. What it won't do is provide comfort on its own: it's the support structure, not the padding, so you'll still need a compatible cushion to sit on. That makes it the right pick when your existing base is gone, bent, or otherwise not doing its job.
Oceansouth Hinged Type Boat Cushions Bench Seat Length 18-inch x Width 12-inch - Gray

This is the cushioned top layer, not the frame. The 18-by-12-inch hinged cushion is filled with thick foam and has a gray cover, so you can place it on a bench that already has support. Because the foam is resilient, it should hold up to regular use without flattening quickly, and the hinged format lets you flip it up when you need access to storage below. The main limitation is size: one cushion covers only an 18-by-12-inch area, so if your seat is wider, you'll need more than one. For a compact bench, though, it's a straightforward way to add seating comfort.
Final Choice by Use Case
- Full seat rebuild: Go with the Toonmate bench seat base, then pair it with a matching cushion.
- Cushion refresh on a small bench: Go with the Oceansouth hinged boat cushion.
- Wider bench seating: The Oceansouth works in multiples, but you'll need to plan how many sections your seat requires.
