The Perception Replacement Seat Pad is made to fit recreational Perception sit inside kayaks.
The seat pad is perfect and makes the kayak much more comfortable
Far too small to fit the seat in my 2001 Perception Eclipse 17' sea kayak. The shape looked right but it's only about three quarters the size, unfortunately. Very thin, too - I tried using it on a 4 hour paddle this week and was sore within the first hour. I really wish Perception sold their newer gel and fabric seats for use in their older kayaks but they don't.
