I purchased this with Wise seats cushions thinking it would be an easy bolt together, I was wrong, I made it work but would have liked better information as I would have done something differently. Maybe they have different versions or a new and old style, but make sure you know what your getting as making it work was a pain...I'm pleasedMy wife and I purchased an old 1985 Weeres pontoon. It had NO seats at all when we purchased it. We have bought 4 of these bases, along with the matching attaching seats. They are super easy to put together with the seat top. They are light and have great storage under the seat within the base.Tried to use old base did not work. Holes not exactly right.This was a replacement of a bench seat that was mistakenly cut to fit a deck access compartment when we have our pontoon seats replaced. The installer made a make-shift door in the side of the seat base that never fit right or kept the under-seat area closed or secure. I was able to install this myself and it looks great and fit perfectly! Now this seat's compartment is secure from want-to-be squatter squirrels :)!Worked fantastic. There was a little problem with the seat hinge fitting just right, but we got that worked out and it looks greatThe color of the white base does not match the color of the white seat. Despite the color difference, it still looks pretty good.made the boat look new againPour mon pontoonmuy buen producto facil de instalar, practico y espaciosoExactly what I needed.
