My seat on my 2010 WX2000T is toast too, it’s like sitting on a hard mushroom now, I’m also the 2nd owner so I really don’t have a dealer to take it to. I contacted Skeeter about it, even though it’s a known and common problem with that model year (and older I presume), all they’d do is sell me a new seat at a “reduced” price. That was about the cost of buying the exact model seat through Cabela’s.
So far I haven’t done anything, I suffered thru another year with the plan of buying a better quality aftermarket seat.
