Who it’s best for: boat owners seeking a complete base-and-pedestal kit to replace or add seats on a wide range of vessels. Why chosen: strong alloy construction with a robust pin post; designed to resist detachment during active use.

CLLOMAGY Boat Seat Base Mount Plate
This 7″ x 7″ base plate is built as a universal non-threaded 3/4″ pin post socket base. It offers a straightforward installation on pontoon, fishing, jon, bass, and cruising boats. The design prioritizes flush mounting with six screw holes to secure the base, allowing the seat post to slide smoothly within the bracket. Best for boaters who want a solid, easy-to-mount deck plate that minimizes wobble.
Best for: anglers and boaters adding an extra seat on flat or slightly contoured decks. Why chosen: simple bolt-down installation, compatible with common 3/4″ post systems. Caution: deck thickness and screw selection must suit the six mounting holes for a secure fit.
Pirjeco SP-68914 Heavy Duty Base
This heavy-duty aluminum base is designed for direct OEM replacement and features a wedge shape to accommodate sloped decks. It fits standard 2″ and 2-3/8″ pin post sockets and is compatible with Attwood SP-28911/SP-28913 and Swivl-Eze SP-37904/SP-37914 bases.

Buying Guide: Key Considerations For Boat Seat Floor Mounts
- Deck compatibility: Confirm post socket size (2″ or 2-3/8″) and ensure the base plate matches your seat post.
- Deck geometry: Sloped or flat decks require wedge designs or deeper base profiles for level seating.
- Corrosion resistance: Aluminum bases resist saltwater and freshwater exposure; check finish quality for longevity.
- Installation requirements: Look for six-hole mounting patterns and deck hole diameter (often around 3.25″).
- Load considerations: Choose reinforced bases for higher seating loads or active fishing setups.
- Compatibility with existing mounts: Some bases cross-reference with Attwood and Swivl-Eze styles; verify before mixing components.
- Number of seats: If adding multiple seats, consider a package or two-pack options to simplify installation.
