Choosing between a boat seat and a seat pedestal can feel like a chicken-and-egg problem: do you start with the part you sit on, or the part that holds it up? In the deck hardware seating covers space, the two products that usually end up side by side are the Millennium Marine B-100 seat and the Springfield Marine locking seat pedestal. This head-to-head helps you decide which one to buy first and how they fit into a complete setup.
Quick Verdict
If you need the part you sit on, get the Millennium Marine B-100. If you need the part that supports and locks that seat into place, get the Springfield 1240020-DAL. The Springfield costs USD 101.99 and the Millennium costs USD 220.00, so the right first buy depends on whether you already have a seat or a base.

Product Notes
Millennium Marine B-100 Boat Seat (Gray Model)

This gray boat seat is the half of your setup that actually supports you when you're out on the water. It's new, with a Millennium Marine part number B100-GY that makes it easy to identify for replacement parts. The gray color works well as a neutral on many deck schemes, and the seat itself is the complete seating surface. If you're starting with a bare deck and want to sit down sooner, this gives you the seat without needing a separate backrest. The main limitation to weigh is the warranty situation: there is no warranty coverage on this item, so you're relying on its initial condition. Keep that in mind before making the purchase.
Springfield Boat Locking Seat Pedestal 1240020-DAL (20 Inch, 2nd Gen)

If your boat already has a seat or you want to add height and locking capability, this Springfield Marine pedestal is the supporting piece. It's an aluminum pedestal with a 9-inch diameter base and six 3/8-inch mounting holes, and it's designed to work with a locking 2 7/8-inch track lock slide or swivel. That makes it a practical foundation for a swivel or slide setup. The catch is that hardware and an instruction/installation manual are not included, so you'll need to source your own mounting bolts and follow standard installation practices.
Final Choice by Use Case
- Need a seat now: Go with the Millennium Marine B-100. It's the boat seat itself, and it's ready to be paired with whatever base you have or choose later.
- Need a locking base: Go with the Springfield 1240020-DAL. It gives you the support and locking function without requiring a separate seat base.
- Building from scratch: If you already have a seat, start with the Springfield pedestal. If you already have a pedestal, start with the Millennium seat. If you have neither, buy whichever piece is harder for you to source and then pair it with the other.
