When you're shopping for deck hardware seating covers, the real fork in the road is whether you need a proper seat or just a better cushion for the bench you already have. One option is a pair of full gray boat seats; the other is a single hinged bench cushion. The price gap between them is large, and it points to two very different ways of upgrading your time on the water.
Quick verdict
Choose the Millennium Marine B-100 pair if you want two complete, matching gray boat seats with the structure of a full seat rather than a pad. Choose the Oceansouth hinged cushion if you have a bench and want a comfortable, lower-priced way to improve the seating surface without replacing the whole setup.
| Product | Listed Price | What It Is |
|---|---|---|
| Millennium Marine B-100 Boat Seat (Gray, 2-Pack) | USD 220.00 | Two full boat seats in gray, part number B100-GY |
| Oceansouth Hinged Boat Cushion Bench Seat (18" x 12") | USD 35.38 | Hinged bench cushion in gray with 2.5" height |
Where each one wins
The Millennium B-100 wins when you need actual seats that can fill two positions on your boat. It's a seat, not a cushion, so it carries the structure and shape you expect from a marine seat. The Oceansouth wins on flexibility and price: it's a single cushion you can move around, fold over a bench, and use without altering the existing setup.
Product notes
Millennium Marine B-100 Boat Seat (Gray, 2-Pack)
If your boat has two spots that need full seats, this gray pair gives you matching units for both. The B-100 is built as a boat seat rather than a bench pad, which means it brings the defined seating shape you won't get from a cushion. The manufacturer part number B100-GY makes it easy to identify the specific gray model. At USD 220.00 for two seats, it works out to USD 110.00 per seat, which is the higher upfront cost between the two options. The limitation is that the seat is sold as a pair, and no warranty is included, so if you only need one seat or want protection against defects, this isn't the flexible choice.
Oceansouth Hinged Boat Cushion Bench Seat (18" x 12")
At USD 35.38, this hinged cushion costs less than a full seat and is a lower-commitment way to make your bench more comfortable. The resilient thick foam is designed to hold up under regular use, and the hinged style lets you fold it over the edge of a bench. The 18" length and 12" width create a compact pad for one seating spot, while the 2.5" height adds a visible layer of cushioning without raising you too high. The trade-off is that this is a cushion, not a seat, so you still need a solid bench or base beneath it. It also won't provide back support or a mounting base for pedestal-style seating.
Final choice by use case
Pick the Millennium Marine B-100 Boat Seat pair if you're replacing two seats and want a matching gray set with full seat structure. Pick the Oceansouth Hinged Boat Cushion if you have a bench and simply want an inexpensive, comfortable pad to sit on.
