Overview

The Attwood Marine 91320-ADJ is an adjustable boat seat pedestal for seating positions that need more height range than a fixed post. It adjusts from 11-1/2 in. to 17-1/2 in. and uses integrated base and seat mounting plates, so it installs as one pedestal assembly.

This setup works well when the same seat is used by different people or when seat height changes your sightline and comfort underway. Reinforced welded joints add strength where the pedestal takes load and movement, and the black powder-coated finish is a better match for the damp, high-use conditions common on open boats.

Key features

• Adjustable height from 11-1/2 in. to 17-1/2 in. to help dial in seat position for visibility and comfort.
• Reinforced welded joints for added strength in a seat base that sees regular movement and deck vibration.
• Black powder-coated finish that handles marine exposure better than a basic painted surface.
• Integrated base mounting plate and seat mounting plate for a cleaner replacement or new installation.
• Built as a dedicated mounting point for a boat seat rather than a separate post-and-bracket combination.

Installation and fit

This pedestal is meant for boat seat mounting, so the main checks before ordering are your existing seat and deck mounting pattern and the final seated height you want once the cushion is in place. If you are replacing a fixed pedestal, measure from the deck to your normal seating position so the 11-1/2 in. to 17-1/2 in. adjustment range lands where you need it.

Because the base plate and seat plate are already part of the assembly, the install is simpler than mixing separate pieces. It is a sensible fit for helm seats, cockpit seats, and fishing positions where one seat needs some height adjustment without moving to a larger pedestal system.

Use on board

This pedestal suits owners who want a practical way to fine-tune seat height for different drivers, changing water conditions, or a better view when docking and maneuvering. It also makes sense on boats where one seating position needs to cover more than one job during the day.
