How to Measure & Replace Your Deckmate Pontoon Boat Seats

Will DeckMate Seats Fit My Boat?

DeckMate seats come in a wide variety of sizes, trims, and colors to customize your boat with ease. Our boat furniture is made to fit any pontoon brand and size.

Replace Your Pontoon Seats Like a Pro

Many pontoons use basic bench seats to fill the deck space, but our pontoon furniture can be used to duplicate an existing seat arrangement or create a new one to maximize space.

Plus, new boat seats improve comfort, style, and function, and upgrading your pontoon furniture is a simple change that can make an old boat feel brand new! Seats can be updated without having to replace the flooring, console, or railings for a simple and quick revamp.

At PontoonStuff, we make it easy to find replacement furniture that fits your boat, budget, and skill level. Follow this guide to learn how to successfully and safely install replacement boat seats yourself!

Why Choose DeckMate Pontoon Boat Seats?

What to Know Before Installing Replacement Boat Seats

  • You don’t have to stick with your boat’s original furniture layout.
  • PontoonStuff furniture fits a wide range of pontoon boats.
  • We carry carpet, flooring, fencing, accessories, and more for full restorations.

Measure Your Pontoon Deck Space

You’ll need a few key measurements to ensure your new boat furniture fits, so grab a tape measure and jot down the numbers using the checklist below:

Pontoon Deck Measurement Checklist

A. Deck width: Measure the distance between the inside of the port and starboard rails.

B. Rear deck space: Measure from the back rail to the side gate.

C. Front deck space: Measure from the front rail to the side gate.

Tip: Most pontoons are 89"-93" wide. Always measure from inside the rails and account for any braces or support posts that could affect seating.

Choosing the Best Pontoon Seats for Your Boat

You're not limited to your boat’s original setup. Whether you want more seating, a fishing upgrade, extra storage, or a different layout entirely, PontoonStuff gives you options.

Curved Front Deck? Here's How to Measure Radius Seats

If your pontoon has a curved front (known as a radius), follow these steps:

1. Measure straightforward from the point where the rail begins to curve to the side.

2. Measure straight to the side from the point where the rail starts to curve at the front.

3. Your radius length is where those lines meet.

Tip: We offer 30" and 36" radius seats, which work for most pontoons. For traditional, tighter radius corners, our 28" corner seats, arm rests, and some lean back seats will typically correspond. If you’re unsure which fits, we’re happy to help!
