Adjustable Height Boat Seat Pedestals & Hardware

Adjustable Height Boat Seat Pedestals & Hardware

Your boat seat starts on the deck. Practically every boat has one or more seats on it that require a mounting pedestal: fold down seats, pro seats, bucket seats, helm seats.

Seat pedestals are made up of a base, post and seat mount. Swivels, slides, and additional hardware can be added depending on the features you want. There are several styles and sizes of boat seat pedestals to keep you comfortable and safe while boating.

Seat pedestals have an ABYC (American Boat and Yacht Council) rating to help you determine which pedestals are safe for various positions on your boat. Type B rated boat seats are designed for low speeds under 5mph. These are perfect for fishing seats. Type A rated seat pedestals are designed to be used at any speed. Type A pedestals are split into driver and passenger position groups. Seat pedestals with this rating are great for bucket and helm seats.

Seat Pedestal Identification

There are four large manufacturers of boat seat pedestals: Garelick, Springfield, Swivl-Eze and Wise. All of these aftermarket manufacturers also supply OEM hardware to boat builders.

Pedestal components from different manufacturers have different tolerances and should not be mixed as it typically voids any warranties. For example, if you have a Swivel-Eze post you should only use a Swivel-Eze seat mount.

Pedestal Size	Springfield	Swivl-Eze	Garelick	Wise	Notes
3/4" Pin	KingPin - Standard KingPin - Threaded	Lock'N-Pin - Standard Lock'N-Pin - Threaded		King Pin - Standard	This is the only size where some manufacturers say brands can be mixed. 3/4" pedestal bases and posts can be either standard or threaded. Threaded bases have a deeper cup under the plate that houses the female threads. The standard, non-threaded base is shorter and only holds the bushing.
1.77"	Spring-Lock has a stainless steel post with mechanical lock on the bottom of post that locks into the base. Used mostly on Ranger Bass Boats and other premium brand bass boats. Clip-Lock has an aluminum post with a bushing on the bottom that expands inside the base for the unintentional detachment. Spring & Clip-Lock parts interchange.	Snap-Lock Series features a larger locking clip with a metal insert that allows the posts to lock into bases for added safety. Just press the button to release.
2" & 2-3/8"	Taper-Lock, ideal for fishing boats, has been widely used by many top-name boat builders for years.	Wedge 2" & 2-3/8" bushing locks in with a tight, solid fit.			Bases between brands often appear identical. However, slight tolerance variations may produce an improper fit if brands are interchanged. The brand of the base can often be found stamped underneath.
2-3/8"	Thread-Lock Series offers a great retrofit to any boat where a seat is needed and you don’t want to go below deck. Low profile base with steady support. Plug-In Series is Springfield's most common system for aluminum pontoon boats. Permanent Pedestals such as the Clipper & Explorer.	Lakesport Series is available as both a removable and a permanent pedestal. 238 Series is available as both a removable and a permanent pedestal. Bases are interchangeable between these two series.		Permanent Pedestals	This size is typically used for freshwater boats.
