thanks for all the information guys.

iwant1... if it was to be a piece big enough to do the whole thing then i would need something that would get 1 x 1200 x 1000 and 1 x 1200 x 500mm and i mean these are very rough sizes, without knowing how that sample would come thats the best info i could give you.

is there a medical grade to this stuff? as the stuff on them play mats is much thicker (it feels thick from how stiff it is) than what i expect is used in furniture infact it's very similar to the stuff these use on chairs in hospitals
