Valley and North Shore kayaks built after 2010 come with this seat bottom. This seat tended to crack in early model year kayaks so Valley added more foam under the seat to reduce the flexing and later yet added aluminum reinforcement angles where the seat bolts into the deck and the back-band attaches to the seat. In our experience, with these improvements the seats have stopped breaking. This seat includes the foam (which you will need to cut to fit your kayak - trim 0.25"-1.00" off the bottom of the foam depending on whether your kayak is an LV, MV, or HV size) and the Left and Right aluminum reinforcement angles for the seat attachments. Seat pad, hip pads and back-band are all sold separately.

We mark arrows pointing toward the front of the seat on the foam pieces and the seat so all you have to do is match them up as in the photo here and glue together with contact cement.
