Very sturdy seat base
This Attwood mount is exactly what you want if you’re looking for a sturdy boat seat base. The steel construction feels heavy duty and built to last, and the spring loaded locking pin engages smoothly with a reassuring click. Once installed, there’s no wobble or play; just a tight, secure fit that gives you confidence out on the water. Installation was easy and everything lined up perfectly. The 2-3/4” post height is ideal for my setup, and the corrosion resistant finish is a must in a marine environment. If you want a dependable seat mount that does its job this one is a winner. Highly recommend.

Strong, Secure, and Smooth – Great Upgrade for My Bass Boat
I installed the Attwood 1002 Lock’N-Pin 3/4” Seat Mount on a new seat and pedestal for my bass boat, and I’m extremely impressed with the quality and performance. The steel construction feels solid and durable, and the spring-loaded design adds a nice bit of cushion and shock absorption when moving around the deck. The fit is tight and secure—no wobble or play in the seat, even when leaning and shifting during casting or running at speed. The Lock’N-Pin system works exactly as advertised, making the seat easy to remove when needed but locked down solid when in place. Installation was quick and hassle-free, and the 2-3/4” steel base paired perfectly with my pedestal. It’s a noticeable upgrade from the standard mounts and really improves the overall feel of my setup. If you’re looking for a reliable, heavy-duty seat mount for your boat, this is a fantastic choice. I’ll definitely be using Attwood hardware again!

Boat seat mounting bracket.
Functioned and fit just as was expected. Paint seams thick so should be durable. Spring is very taunt. No mounting screws are included. Easy to install on bottom of boat seat. Lo9ks good on the boat.

Very sturdy and durable.
My husband got these for his fishing boat seats, he says they are easy to install and do exactly what they're meant to do. So far they seem very durable and as if they'll last a long time and many summers to come. He is glad he had me order them. The seats are alot more sturdy now

取り付けも、椅子との相性もぴったりでした。シャフト部分は経年によっては錆びが出ると思いますが、仕方ないですね。
