If it is a flexible polyurathane foam it is most difficult to clean(an upholstery steam cleaner would be your best bet) but if it is a polyetheylene foam those are quite easy to clean as they have no sponge type qualities.....the problem with the P.E. foam is that it tends to be quite firm(almost as firm as a hard seat) unless you get one of very low weight and quality(say a 1.2# - 1.7#)versions....anything above a 2.2# will just be way too firm for a seat that's supposed to be soft. Another option would be to use flexible extruded vinyl accatate(EVA). This foam is somewhat spongy in feel but still what they call a closed cell foam(will not absorb moisture)...in fact, this stuff is used in life vests for floatation. Be carefull when choosing this stuff though because it also can come in a very firm ILD....you will want to get something soft so ask for a "Y-20 EVA soft". The biggest problem with EVA is that it costs nearly 3 times as much as the other two foams. For the Cadillac of foams choose CONFOR foam. This stuff is a memory foam but nothing like the memory foams they sell for beds....it is super dense and conforms to ones posterior using the science of NASA. It is an open cell foam so it will be difficult to clean, but man is it comfortable.....this is the stuff Jet fighter pilots sit on when pulling 4+ gs. ---------------------- What?
