Attwood Marine 278 Pro Boat Seat Pedestal Base, Fixed, Gray

Overview

The Attwood Marine 278 Pro Pedestal Base is a fixed-height boat seat pedestal base for 278 Pro seating setups where a steady helm or cockpit seat position matters. The range uses a bell-style pedestal with a 2-7/8 inch post and is offered in multiple fixed heights, giving builders and boat owners a way to match seat height to the console, deck layout, and visibility from the helm.

This pedestal base is suited for helm seating, fishing seats, and other cockpit seat positions that need a firm base rather than height adjustment. Its fixed layout keeps the seat at a consistent height underway, while the 278 Pro platform is made for use with compatible Attwood 278 seat hardware.

Key features

• Fixed-height pedestal base for boat seating positions that do not need on-the-water height adjustment.
• 2-7/8 inch post size for integration with compatible 278 Pro seating components.
• Bell-style base gives the pedestal a wide footprint for steady seat support on deck.
• Heavy casting supports common oversized helm seats when matched with the correct 278 Pro hardware.
• Useful for helm, cockpit, and fishing seat locations where sightline and seat height are set during installation.
• Available across several base heights so the seat position can be matched to the vessel layout.

Variants

This 278 Pro Pedestal Base range varies by base height. The available heights run from 6 inches through 13 inches, so the main choice is the finished seat elevation needed for the mounting location.

The shorter heights are commonly useful where the deck or seat cushion already sits high, while the taller heights help raise the seating position for helm visibility or cockpit comfort. Confirm the total installed seat height with the seat, swivel, slider, and deck surface before ordering.

Installation and setup

Before installation, check that the deck or mounting surface has enough backing and clearance for the fasteners used with the seat base. A pedestal seat carries side loads when the boat turns, accelerates, or runs through chop, so the mounting surface should be solid and properly reinforced.

Dry-fit the pedestal with the seat and any swivel or slider hardware before drilling. This helps confirm reach to the wheel or controls, legroom, and visibility over the console or windshield. For saltwater boats, use appropriate marine fasteners and bedding practices for the deck material.

Compatibility and fit

This pedestal base should be matched with compatible Attwood 278 Pro seating components and the correct seat hardware for the boat. The important fit points are the 2-7/8 inch pedestal size, the selected fixed height, and the available mounting area on deck.

It is a practical match for boat owners replacing an existing 278 Pro pedestal or setting up a fixed helm, cockpit, or fishing seat where a simple, non-adjustable seating position is preferred.
