Anodized 2-3\/8 inch aluminum post, 9 inch base, ABYC Code H-31 AD compliant. Set it once and forget it.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eIf you've ever spent a long day on the water fighting a seat that sits too low at the wheel or too far back from the throttle, you already know why an adjustable pedestal is worth the money. The Springfield Marine 1253031-L gives you a manual height-adjust post that runs from 13-7\/8 inches up to 16-7\/8 inches, plus a built-in seat slide so you can move fore and aft to find the sweet spot. Set your helm chair once, lock it in, and you're done.\u003c\/p\u003e\n\u003cp\u003eThe post itself is 2-3\/8 inch anodized aluminum, which is the standard heavy-duty diameter for boats that see real use. That extra wall over a lightweight post matters when you're standing up on plane in a chop and putting your full weight against the seat back. It doesn't flex, it doesn't creak, and the anodizing shrugs off salt spray far better than bare aluminum. This is a pedestal built for a center console, a walkaround, or any helm station where the captain is on their feet as much as they're sitting.\u003c\/p\u003e\n\u003cp\u003eThe height adjustment is manual, and that's a feature, not a compromise. There's no gas cylinder to lose its charge over a few seasons and no air valve to leak. You lift, you set the height you want across that three-inch range, and it holds. Pair that with the seat slide and you can get the exact reach to the wheel and throttle that fits you, whether you run the boat at 6 foot 4 or you've got a shorter first mate who takes the helm on the ride home.\u003c\/p\u003e\n\u003cp\u003eIt ships with the 9 inch diameter base and the seat mount, so this is a complete swap for a worn-out pedestal, not just the post. The 9 inch base spreads the load across a wider footprint, which is what you want on a fiberglass deck. One install note from experience: if you're mounting to a cored deck, back it up with a 3\/8 inch aluminum or starboard backing plate under the deck. A 9 inch base takes a lot of load when someone drops into the seat in a following sea, and a backing plate spreads that force so the gelcoat doesn't stress-crack around the bolts over a couple of hard seasons. Bed the base and the fasteners in a quality marine sealant, snug everything down evenly, and you'll never chase a leak from the mount. It's ten extra minutes at install that saves you a soft deck down the road.\u003c\/p\u003e\n\u003cp\u003eThe whole assembly is built to ABYC Code H-31 AD, the industry safety standard for boat seat pedestal systems. That's not marketing. It means the pedestal and mount were engineered and tested to hold up under the loads a seat actually sees underway. When you torque the seat mount down to spec, you get a helm chair that stays put when the bow comes off a wave.\u003c\/p\u003e\n\u003cp\u003eSaltwater guys, a word of advice we give everyone: anodized aluminum is tough, but the base bolts are where corrosion starts if you mix metals. Use isolation washers between stainless fasteners and the aluminum base, rinse the pedestal down when you rinse the boat, and a light shot of marine grease on the post threads keeps the manual adjustment moving smooth for years. Do that and this thing outlasts the seat bolted to it.\u003c\/p\u003e\n\u003cp\u003eWho's this not for? If you've got a fixed-height helm chair you never plan to touch, a fixed pedestal is cheaper and simpler. But if more than one person runs your boat, or you fish standing and cruise sitting, the adjustable post and slide earn their keep every single trip. Anglers love being able to drop the seat down and out of the way when they're working the deck, then raise it back up to run home. And on a family boat, being able to set a comfortable height for whoever's at the wheel keeps everybody happy on a long day out. It's the kind of upgrade you don't think about again once it's in, because it just works the way a helm seat should.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eManual height adjustment from 13-7\/8 in to 16-7\/8 in for dialing in helm or fishing height with no gas cylinder to lose charge\u003c\/li\u003e\n  \u003cli\u003eBuilt-in seat slide moves the chair fore and aft so you set exact reach to the wheel and throttle\u003c\/li\u003e\n  \u003cli\u003e2-3\/8 in heavy-duty post diameter resists flex when you put your weight against the seat back on plane\u003c\/li\u003e\n  \u003cli\u003eAnodized aluminum construction shrugs off salt spray far better than bare aluminum\u003c\/li\u003e\n  \u003cli\u003e9 in diameter base spreads the seat load across a wide footprint on the deck\u003c\/li\u003e\n  \u003cli\u003eBuilt to ABYC Code H-31 AD, the industry safety standard for pedestal seating systems\u003c\/li\u003e\n  \u003cli\u003eIncludes the base and seat mount for a complete pedestal swap, not just the post\u003c\/li\u003e\n  \u003cli\u003eManual locking adjustment with no air valve or cylinder to leak or fail over time\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Springfield Marine reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eHow does the height adjustment work?\u003c\/summary\u003e\n    \u003cp\u003eIt's a manual adjustment.
