Attwood builds the pedestals, posts, and swivels that hold your boat seats. Match the post diameter, height, and swivel to your seat and how you use the spot.
A boat seat is only as solid as what holds it up, and Attwood has built marine seat mounts for generations. This collection covers pedestals, posts, bases, swivels, and slides. Choosing right comes down to the post diameter and system, the height you need, and the swivel and slide features that match how you fish or cruise.
Match the post system and diameter
Marine seat posts come in standard diameters, most commonly the 3/4-inch pin-style post and larger pedestal tubes. The post and base have to match, so identify your existing system before ordering. Pin-style posts drop into a base and lift out for storage, which is handy on small boats and jon boats. Threaded and locking pedestals give a more permanent, solid mount.
Fixed or adjustable height
A fixed post sets one seating height, which is simple and strong. An adjustable or telescoping post lets you raise the seat to see over the bow or stand to fish, then drop it back down. Measure your current seating height and pick fixed or adjustable based on how you use the seat.
Swivels and slides
A swivel base lets the seat rotate, and a locking swivel holds it at set positions so it does not spin underway. A seat slide moves the seat fore and aft for legroom or to reach the helm. These add comfort and flexibility, so add them where you sit for long stretches.
Match the base to your deck
Bases bolt to the deck, and the bolt pattern has to suit your seat and the deck structure. Through-bolt the base with backing where you can, since a seat mount takes real load when the boat pounds. A removable base lets you pull the seat and free up deck space for fishing or loading.
Match the seat and the load
Confirm the pedestal and base are rated for your seat and use, and that the post fits both the seat swivel and the base. A mismatched post wobbles, which is hard on the hardware and uncomfortable underway. Not sure which Attwood mount fits your boat? Tell our crew your seat, the heights you want, and your deck, and we will match the post, base, swivel, and slide so the seat mounts solid and works the way you fish.
Frequently Asked Questions
What post diameter do I need?
Marine seat posts come in standard diameters, most commonly the 3/4-inch pin-style post and larger pedestal tubes. The post and base must match, so identify your existing system before ordering.
Pin-style or threaded pedestal?
Pin-style posts drop into a base and lift out for storage, which is handy on small boats. Threaded and locking pedestals give a more permanent, solid mount. Choose based on whether you want to remove the seat easily.
Should I get a fixed or adjustable post?
A fixed post sets one height and is simple and strong. An adjustable or telescoping post lets you raise the seat to see over the bow or stand to fish, then lower it. Pick based on how you use the seat.
What does a locking swivel do?
A swivel base lets the seat rotate, and a locking swivel holds it at set positions so it does not spin underway. Add a slide too if you want fore-and-aft adjustment for legroom or reaching the helm.
How do I mount the base securely?
Through-bolt the base to the deck with backing where possible, since a seat mount takes real load when the boat pounds. Match the bolt pattern to your seat and deck, and a removable base lets you pull the seat to free deck space.
