Wise 8WD100-1B-204 DLX Series Pontoon Bench Seat Base
Best for pontoon benches where a storage-access base is needed. This base is designed for 37″ DLX Series cushions and includes a hinged lift-up design to access storage. It uses high-density rotational molded plastic to resist sun, heat, rain, and scuffing in normal marine conditions. Choose this for a clean, enclosed storage solution under the seat.
boat owners upgrading a pontoon or large deck with DLX cushions, needing a sealed under-seat compartment and durable exterior. Limitation: cushions are sold separately, so the total seating unit requires additional components.
CLLOMAGY Boat Seat Base Mount
Best for universal, straightforward mounting to a variety of deck configurations. The base supports standard 3/4″ pin post sockets and allows flush mounting after drilling a deck hole. It’s a practical choice for deck upgrades on pontoon, fishing, jon, or bass boats where a secure, easy-to-install pedestal is desired.
Who it’s for: DIY installers seeking a simple, robust pedestal base. Limitation: not all post sockets end-to-end include hardware; screws are typically not included.
Attwood 90720 Black Powder Coated 7″ Seat Pedestal
Best for reliable, built-to-last mounting points. This pedestal features a sturdy base with reinforced welded joints and an integrated base and seat mounting plate. It’s a versatile option that works well in most small to mid-size boats requiring a stable and simple pedestal upgrade.
Who it’s for: boaters needing a durable, mid-range pedestal with established compatibility. Limitation: novelty features like extra tilt are not part of this model.
MATINA Boat Seat Base, 7″ x 7″
Best for corrosion resistance and lightweight needs. The 7″ x 7″ aluminum base uses an acetal bushing to fit standard non-threaded 3/4″ posts, offering a smooth, secure seat solution for pontoon, fishing, or cruiser boats. The aluminum construction resists rust, delivering long-term performance with lighter weight than steel options.
Who it’s for: boaters prioritizing corrosion resistance and reduced deck load. Limitation: aluminum may be less quiet than plastic in some deck environments, and fabrication tolerances can vary by batch.
Attwood 1002 Lock’N-Pin 3/4″ Seat Mount
Best for quick-release or replace-and-go setups. This mount uses a 2-3/4″ steel pin with a spring for a softer seating action and a black E-coated seat mount with a slight tilt. It provides a simple, adjustable mounting point ideal for boats that need easy seating changes.
Who it’s for: users who value quick adjustments and a compact mounting profile. Limitation: tilt is modest at 3 degrees, limiting extreme seat angles.
marinexplore Boat Seat Base
Best for a robust 7″ x 7″ base built to support 3/4″ pin post sockets on jon and small fishing boats. The stainless steel construction offers excellent corrosion resistance, reducing rust and maintaining a clean appearance. It is well-suited for saltwater environments and frequent use.
Who it’s for: boaters needing a durable stainless option with universal fit. Limitation: stainless bases can be heavier and may require careful deck cutouts for flush mounting.
Buying Guide: Key Factors To Consider
- Deck compatibility: Confirm the post size (3/4″ pin post is standard) and whether the base requires a specific deck hole diameter or mounting pattern.
- Material choice: Aluminum bases resist corrosion and are lighter; stainless steel offers extreme durability in saltwater but adds weight. Plastic bases can be budget-friendly but may wear faster in sun exposure.
- Mounting method: Decide between integrated mounting plates, base-only designs, or pedestal systems that allow easy removal for transport or storage.
- Intended use: Pontoon seating often benefits from hinge-access bases for storage; fishing boats may prioritize a lower profile seat with stable post support.
- Installation effort: Some bases require drilling and multiple screws; others use simple bolt-on or pin-post drop-in styles. Check for included hardware or whether you need to source screws separately.
- Corrosion resistance: For saltwater or high-humidity environments, prioritize corrosion-resistant materials like stainless steel or coated aluminum.
- Weight considerations: Lighter bases reduce deck stress, especially on smaller boats; heavier bases typically offer added stability.
Practical Buying Tips
- Look for bases that match your boat’s existing pin post socket size and deck thickness.
- Consider whether you prefer a base with an integrated storage solution or a simple pedestal base for flexibility.
- Assess installation space: taller pedestals can affect seating height relative to rails and walking space.
- Check for compatibility with your cushions or benches if upgrading an entire seating system.

- Do I need hardware with the base?
Some bases include mounting hardware; others require screws or bolts to be purchased separately. Check product details.
