DeckMate Pontoon Furniture Quality Story

Our DeckMate® pontoon furniture stands out because we build it with better materials, and back up our quality with a 5-year warranty. You know you're getting the highest quality pontoon boat seats because no other manufacturer will match that guarantee. And since we design, build, and sell our pontoon seats directly, we can offer superior furniture at affordable prices.  

What's our difference?

  • Our Premium pontoon boat seats use plush, pillowed seat cushions with a mixture of soft and dense marine foam for all-day comfort. We use double-top & standard-top stitching on all stress points, so you never need worry about torn seams. Our pontoon boat seats look new longer! 
  • Our pontoon boat seats will last. The quality of the vinyl used on your pontoon boat seats won't matter if your seams tear or rot. That's why we use the best UV & mildew treated polyester thread. SunStop® thread (click for info) is designed specifically for the outdoors. Many pontoon furniture manufacturers use the same nylon thread used in office furniture because it's cheaper, but this thread will not last longer than 3 years in the sun.
  • 30oz marine-grade seat vinyl is coated and treated with antimicrobial agents and UV stabilizers to exceed industry standards for UV and mildew resistance. This is one of the most important features of our pontoon seats. When you see aftermarket pontoon furniture that has mildewed or begun to crack prematurely, it's often because the manufacturer used poor quality vinyl to keep costs low. This won't happen to our pontoon boat seats. With top-quality treated vinyl, you won't need to replace them after 3 years.
  • Our pontoon boat seat cushions are built with a mix of soft and dense foam to give you support and comfort where it matters most. Our Premium pontoon boat seats are built with thicker, softer seat cushions.
  • The fully enclosed plastic bases used on our pontoon boat seats have molded drain channels designed into them to increase the life of your pontoon's deck. When water is allowed to escape your deck quickly, instead of being trapped and left to soak into your carpet and decking, the lifespan of your flooring greatly increases.
  • No wood! All of our pontoon furniture frames are plastic. We use injection-molded plastic seat cushion frames and rotationally molded plastic seat bases.
  • High-grade stainless steel hardware and staples are used on our pontoon seats, along with t-nuts, which are inserted into the plastic bases to secure each pontoon seat cushion.

  • We pay all costs associated with any damaged or defective seating. There is never any cost to you.
  • 100% transferable warranty - if you sell your pontoon boat, the buyer is covered. If you're a second owner, just provide us with the original owner's name or order number.

Our History

PontoonStuff® was founded on the idea that rebuilding a pontoon boat should be affordable and that you shouldn't need a payment to get that new boat feeling. With factory-grade pontoon furniture, flooring, and parts, we make it affordable to have a great-looking pontoon boat again!

Here are some quick facts about us:

  • We've been in business since 2005, and have helped over 200,000 customers fix up their pontoons. We sell to an average of 35,000 new customers per year.
  • We sell more replacement pontoon boat seats than all other marine retailers combined, and focus on offering everything you need for your pontoon restoration.
  • Designing, building, and selling our pontoon boat seats directly gives us a big advantage: We can invest more in quality because we control the entire process. 
  • All products are stocked and shipped from our facilities in Elkhart, IN and Dalton, GA.

Before building our own DeckMate brand of pontoon furniture in 2012, we sold nearly every brand of replacement pontoon seating, so we understand what makes a high-quality seat. Because of our experience with other seat brands, we knew where to focus our efforts in order to offer superior quality pontoon boat seats.

Questions & Answers

Ask a Question
  • How is this furniture installed? Also, what do the seat backs look like? Thanks.

    The back rest seat cushion is completely upholstered over an injection molded plastic frame. At the bottom a section of the seat frame protrudes slightly and you drop it into a channel on the plastic base so it can be bolted down.  Our 55" pontoon seats will arrive to you in 2 boxes. One box will contain all the seat cushions and hardware and the other will contain the 2-27.5" wide bases that will support the cushion set. To install first you will insert threaded stud bolts into the back rest frame and drop it in place on the base (the base has a channel that the back rest drops into). Once in place you simply attach the back rest with wing nuts and then hinge the seat cushion down to the bases. Hinges are pre-installed on all of our pontoon seat cushions so you just secure the bolts to the t-nuts that are on the plastic base. It a pretty simple process, thank you.

  • What hardware do I use to install the new seats to my deck?

    All of our pontoon furniture bases will come with stainless screws that you can use to attach your seat bases to the deck of your pontoon (4 screws will be in a packet in each plastic seat base). Once you have all the pontoon seats in place you can use a screw in each corner of the base to secure it to the deck, nothing more is really needed. One thing that almost all pontoon manufacturers also do is run sheet metal screws through the outside railing directy into the back rests of the pontoon seats. We don't provide hardware for this as we found most customers get to nervous to run screws though the uphostery but if your railing has holes in it I'd recommend getting some sheet metal screws and securing the backrests of each pontoon seat to the rail. This will not void any warranty and it will help to greatly strengthen the railing and the furniture on your pontoon, holding everything together very nicely. 

  • Can you buy cushions separate

    Unfortunately we don't sell just the seat cushions but we do replace cushions on our seats. The reason we don't offer them separate is our seats are designed to fit our bases so the hinge points will not line up with what you have. Also, our seat cushions are much deeper than most and they just can't fit unless you build a custom base for it. I wish we could be more helpful. 

  • How much does the 55 inch seat weigh? Thanks

    Our 55" pontoon boat seats weight approx. 80lbs, this includes all the seat cushions and the plastic bases.

  • does the base come with the seat

    Yes, all of our pontoon furniture comes with the seat cushions and the plastic bases plus all the mounting hardware you'll need for assembly and installation on your pontoon boat.

  • Does the back rest need to be supported by railing?

    Yes this pontoon seat will need to be supported agains the railing on your pontoon boat. 

  • I plan to mount speakers in several seats. Are the seat bases double walled or single walled? Wondering if I'll need to fish wire between and if I have to be careful of the depth of my speakers. Thanks!

    They are single walled bases. You can easily cut into the bases with a jig saw. You will have plenty of room for the speakers and to run your wire because the ponroon base opening is large.

  • What is the overall depth of this seat. I see the seat cushion is 19" does this measurement include the backrest also or just the seating ? Thank you

    The overal depth of this pontoon seat is 27". The 19" measuerment is the depth of the seat cushions only not including the back rest of the pontoon seat. 

  • What is the height of this seat. Thanks

    From the floor of your pontoon to the top of back rest of this seat is 30".

  • Hi , I noticed on some of seats it says , must be supported by rail , I'm looking at the 55" on this model it doesn't say that , I'm looking to put multiple 55" bench seats , but I have no rail to support back rest , will the 55" model be strong enough free standing with rail for back support ?

    I'm sorry about the confusiion but are we in the process of updating all of our listings. The 55" pontoon bench seat does need to be supported by the rail or some type of support system. 

  • What brand vinyl do you use for the seats? If I order seats, can I purchase a few yards of additional vinyl for our sun deck on the boat?

    Yes, you can purchase vinyl separately if you need to match our Pontoon Cushions to your sundeck. I will attach a link that will take you where the vinyl is sold. https://www.pontoonstuff.com/collections/premium-pontoon-boat-seats/products/pontoon-boat-seat-vinyl

  • Are these seats available in solid white? (e.g. - no colored stripes).

    No. The only colors that we have available for the 55" Pontoon Bench Seats are the ones located in the drop down menu.

I bought this along with $3000 worth of furniture. When it came I was a bit concerned about the stability of the plastic bases but that was a non issue. Once mounted the furniture is stable and secure. The cushioning and fabric are really nice. It looks good and surprisingly does not get too hot in the AZ sun. That was the best surprise.

Once mounted the furniture is stable and secure. The cushioning and fabric are really nice. It looks good and surprisingly does not get too hot in the AZ sun. That was the best surprise. The only improvement would ne te hardware used to secure the seat. This 55" is actually two 27 1/2" bases and as such the screws holding the seat to the hing and the ones holding the hinge to the base interfere with one another. I had to adjust the seat to a position that is not ideal to make the clearance needed. Also the seat screws are phillips headed sheet metal screws and quite hard to turn in the plastic seat bases. It may increase production cost but a flat allen headed screw would work much better. All in all I'm VERY happy with the furniture and pontoonstuff is great to deal with.
