Springfield Marine

<h3>About Springfield Marine</h3><p>Few names carry as much weight in the world of marine seating as <strong>Springfield Marine</strong>. With roots stretching back to 1952, when the Springfield Aluminum Company was established as an aluminum foundry, the brand steadily grew into one of the most recognized manufacturers in the boating industry. By the late 1970s, Springfield had firmly established itself as a go-to source for marine seating hardware — and it has never looked back. Today, the company is widely regarded as a leader in both freshwater and saltwater marine seating solutions.</p><p>What sets Springfield Marine apart is a relentless commitment to engineering products that can withstand the real demands of life on the water. The brand relies on materials like high-strength anodized aluminum, stainless steel, and protective E-coatings — finishes proven to hold up against corrosion in everything from calm inland lakes to punishing saltwater offshore environments. Every product is designed with both recreational boaters and working professionals in mind, blending ergonomic comfort with the structural durability that serious boating requires.</p><h3>Innovative Pedestal Systems</h3><p>Springfield Marine has built its reputation largely on the strength of its pedestal systems. Their <a href="/7586-springfield-marine-tables-pedestals-201044">Tables &amp; Pedestals</a> lineup includes some of the most versatile solutions available, from air-powered 3-stage table pedestals that adjust to multiple heights without requiring a floor hole, to 12V electric actuated pedestals that wire into any onboard switch and offer positions ranging from deck level to full dining height. These pedestals are built from high-strength aluminum and are rated for serious load capacity, making them as functional as they are durable.</p><p>The brand's proprietary systems — including the KingPin™ and SpringLock™ pedestal platforms — offer boaters a flexible, tool-free approach to managing deck space. These removable designs are especially popular with anglers who need to quickly reconfigure seating to suit changing conditions on the water.</p><h3>Complete Seating Solutions</h3><p>Beyond individual components, Springfield Marine offers thoughtfully curated <a href="/7586-springfield-marine-seat-pedestal-packages-200926">Seat &amp; Pedestal Packages</a> that pair compatible seats and mounting hardware into ready-to-install systems. This takes the guesswork out of mixing and matching components, ensuring proper fitment and balanced performance straight out of the box. Whether you're rigging a bass boat, a center console, or a pontoon, Springfield's packaged solutions make it straightforward to upgrade your onboard comfort.</p><p>Springfield Marine's product development philosophy centers on continuous improvement — working with industry associations and boating customers alike to refine existing designs and introduce new innovations. The result is a catalog of over 150 products that cover seating hardware, mounting systems, tables, and accessories, giving boat owners a single trusted source for outfitting their vessels from stern to bow.</p>

Best price. Received confirmation of shipment two days after placing order. Hoping to see product soon.

Good communications and prompt shipping. Price was cheapest I could find.

I found what I wanted and it was so fast and easy

Cannot say enough about how honest these guys are. My order went through without a hitch. Would definitely recommend doing business with them.

Pretty clear. Forms are simple. Parts are easy to find

Fantastic prices, lowest on the 'net. Easy ordering, easy pay and fast fast fast shipping. You can't go wrong!

Autoplicty had the best price by far for a transmission. Fast shipping too!<br>UNFORTUNATELY...FED-EX beat the hell out of it! It was hanging out of the box when it arrived but was not damaged other than a few scrapes. Fed-Ex is not the best way to ship 140lbs...they can't lift it! Oh, and they can't comprehend "this side up" either!

Best price for a product I've been shopping for, for months, and when I saw Autoplicity having it for A LOT cheaper, putting the product in my sweet spot price wise, I didn't hesitate to order. <br><br>My bank was a little slow to post the transaction, and I was suprised to get a human on the phone with no effort to make sure my order was properly processed. The gentleman I spoke with was very friendly and promptly answered all my questions. <br><br>Only the $5 I'm getting back for this review can make this deal any better, as I have no suggestion for improving the transaction I made with them.

Great price & part in stock & was told would ship today !

So far so good

Product was exactly what I ordered and was sent fast. I will definitely order more products from Autoplicity. Great Site, fast service!
