Canoe seat padding

Looking for ideas of where to buy closed cell foam padding to wrap around canoe seats to make it more comfortable.

On the cheap. Walmart

Garden Kneeling Pads - e-bay

Quarter inch thick minicell foam works reasonably well:

Get a blemish Thermarest Ridgerest pad and cut a section to fit. Very comfortable as it is designed as a sleep pad.

puddlecrew,
If this is for your team in the 90 miler, there will be a vendor outside the registration building tomorrow night that will have precut pieces of foam available at a very reasonable cost. Otherwise a cheap sleeping pad from any outdoor store or Walmart.
