Beginning Again

I just found in the back of a old Garage a Kayak it is a wilderness systems Mantero 1999 yr model, my question is ? Needing a new seat what after market seat would would well, I did contact wilderness sys and because of the age of the kayak they do not have parts for it. SO if anyone could help me out that would be great.

You can carve your own seat
out of minicell foam, or purchase a precarved seat from Redfish which just needs to be fitted to your boat.

Of course there are many other choices as well, but I have a redfish seat and it is very nice.
