<h3>About Swivl-Eze: The Marine Seating Authority</h3><p><strong>Swivl-Eze</strong> has earned its reputation as one of the most trusted names in marine seating hardware, serving everyone from weekend lake-goers to professional boat builders and competitive anglers. A brand under the Attwood Marine family, Swivl-Eze is recognized throughout the boating industry as a leading supplier of components to OEM boat manufacturers — companies that demand engineering excellence and uncompromising durability before a single product earns a spot on their vessels.</p><p>At the heart of the Swivl-Eze lineup are <a href="/12827-swivl-eze">boat seat pedestals, seat mounts, and seating bases</a> engineered to keep you stable and comfortable no matter what the water throws at you. Whether you're rigging out a fishing boat, a pontoon cruiser, or a high-performance hull, Swivl-Eze products are designed to deliver a secure, wobble-free seating experience — even in rough, choppy conditions. The brand's products are constructed from corrosion-resistant aluminum and stainless steel, materials chosen specifically to stand up to saltwater, UV exposure, and the general punishment of life on the water season after season.</p><p>One of the hallmarks of the Swivl-Eze system is its breadth of pedestal options. From fixed-height posts ideal for captain's chairs to fully adjustable and power pedestal models that let you dial in your exact seating position, the lineup covers every boating scenario. Proprietary locking systems like the <strong>Snap-Lock</strong> and <strong>Lock 'N Pin</strong> mechanisms make height adjustment fast, intuitive, and rattle-free — a detail that seasoned boaters genuinely appreciate after a full day on the water. The flagship <a href="/12827-swivl-eze">238 Series pedestals</a> are a particularly popular choice for high-performance and fishing boats, featuring a heavy-duty 2-3/8-inch post diameter built for maximum stability and smooth 360-degree seat rotation.</p><p>Beyond seating, Swivl-Eze rounds out its catalog with <a href="/12827-swivl-eze">transom savers</a> that protect your outboard motor and steering components during trailering, and <a href="/12827-swivl-eze">ski pylons</a> that give water skiers and wakeboarders a high towing point for reduced drag and better pull. Every product in the lineup undergoes rigorous testing in Attwood's in-house lab facilities, ensuring that engineering innovation meets real-world performance standards.</p><p>Whether you're a seasoned boat builder sourcing OEM-quality hardware or a DIY boater upgrading a tired seating system, Swivl-Eze provides the reliability, versatility, and marine-grade toughness that every time on the water deserves.</p>

Great

Fast and easy

easy

I ordered a part that did not fit, returned no hassles. I just ordered two items and hope they look great.

This was my first time buying from Autoplicity. I had never heard of the site but gave it a shot. I ordered an Autometer gauge and pod and paid less than the price of just the gauge at other vendors. The two items shipped a day later (I ordered Sunday, shipped Monday). I have no complaints at this time.

Easy fast and good price

very good price and prompt shipping. good choice of merchindise<br>to chose from. helpful in finding the correct item.
