Springfield Marine Mainstay Air-Powered Adjustable Pedestal 1250100-L1, 2-3/8" Post, 14"-20", Locking Swivel

The Springfield Mainstay 1250100-L1 is an air-powered adjustable boat seat pedestal built for boaters who want fast, tool-free height changes at the helm or companion seat. A gas-cylinder mechanism lets you raise or lower the seat through a 14 inch to 20 inch range and lock it firmly at the height you want, so the pedestal adjusts with the user rather than staying fixed at one setting. The post measures 2-3/8 inches in diameter and mounts on a 9 inch round base for stable, secure footing on deck.

Construction is alloy steel finished with a rust-resistant anodized coating, chosen specifically for marine environments where saltwater and constant sun exposure would otherwise corrode an unprotected pedestal. The 1250100-L1 includes a locking Trac-Lock swivel, allowing the seat to rotate and then lock in place when a fixed position is needed, such as while driving. No assembly is required out of the box, and the pedestal is backed by a 5-year warranty. It is retail packed one per box with a 4-color label.

This pedestal suits helm seats, companion seats, and other boat seating locations where an adjustable-height, swiveling post is needed. Buyers who need a slightly taller adjustment range should note that Springfield also offers the 1250150-L1 version, covering 14.5 inches to 20.5 inches, as a separate part number.
