Swivl-Eze Pedestals - 238 Series

What Are Swivl-Eze 238 Series Pedestals?

The 238 Series pedestal system is defined by its 2-3/8-inch post diameter — a specification that has made it one of the most widely adopted boat seat hardware platforms among American fishing boat builders. Whether you're outfitting a bass boat, a center console, or a high-performance sport fishing rig, these pedestals provide the structural foundation that keeps your seating safe, comfortable, and properly positioned on the water.

At their core, 238 Series pedestals consist of three main elements: a base plate that mounts to the deck, a post or tube that sets the seat height, and a seat mount that attaches to the underside of the chair. Each component can be selected individually or purchased as part of a complete kit, giving boaters the flexibility to build a custom seating system or replace only the part that's worn.

Fixed vs. Adjustable: Choosing the Right Post

One of the most important decisions when shopping the 238 Series is whether you need a fixed-height or adjustable post. Fixed posts offer simplicity and exceptional rigidity — ideal for captain's chairs and helm positions where the seat height never changes. Adjustable pedestals, on the other hand, allow you to dial in the perfect seating height for different activities, such as moving from a low trolling position to a higher vantage point for spotting fish.

Some 238 Series configurations also feature snap-lock or power pedestal designs, which let you raise or lower the seat with minimal effort — a real advantage during long days on the water. Snap-lock mechanisms make it easy to remove the seat entirely when you need more open deck space for casting or landing fish.

Materials and Construction

The marine environment is one of the harshest conditions any hardware can face. That's why 238 Series components are built with hard-anodized aluminum tubes that resist corrosion and maintain their structural integrity season after season. The bead-blasted finish on many bases closes the surface to porosity, which is then clear-coated to guard against long-term rust and chalking — a critical detail in both freshwater and saltwater applications. Springs within the mechanism are typically stainless steel for added corrosion resistance.

All 238 Series hardware is engineered to meet or exceed ABYC (American Boat and Yacht Council) standards — the benchmark safety guidelines for marine seating systems. ABYC standards define load criteria for both fore-and-aft locking and vertical adjustment mechanisms, so you can trust that a properly installed 238 Series setup is built to handle real-world on-water forces.

What's Included & Compatibility

The 238 Series product lineup spans individual components — posts, bases, seat mounts, and extension posts — as well as complete pedestal kits that bundle everything you need into a single purchase. Most kits include a standard 5-inch x 5-inch seat mount pattern, which is compatible with the vast majority of aftermarket and OEM boat seats. Before purchasing, always verify the post diameter, base diameter, and overall height range to ensure a proper fit with your existing deck hardware and seat.

• Post-only pedestals — ideal for replacing a worn or damaged tube without changing other components
• Complete pedestal kits — base plate, post, and seat mount included for a full installation
• Extension posts — add height to an existing pedestal setup
• Adjustable pedestals — variable height ranges, often with locking nylon handles
• Power pedestals — mechanically assisted height adjustment for effortless repositioning

Who Should Use 238 Series Pedestals?

These pedestals are a top choice for anglers and boaters who demand dependability. The heavy-duty construction handles the dynamic loads that come with rough water, aggressive maneuvers, and the constant boarding and exiting that fishing trips demand. If you're upgrading an aging seating system, replacing a corroded post, or building out a new custom seating layout, the 238 Series offers a proven, widely-used platform with broad parts availability and a range of configurations to match nearly any application.
