The Attwood LakeSport Extension Post is a fixed-height pedestal seat extension standing 13 inches tall, built to raise seating height on a fishing, pontoon, or cruising boat.
It’s a direct fit for 238 LakeSport seat mounts and socket bases, giving a straightforward way to add elevation to an existing seat setup rather than replacing the whole mount.
At 2-3/8 inches, it matches the standard diameter most LakeSport hardware uses, keeping the whole system consistent. Shop more seats, pedestals and slides.
