Just bought my first bouldering mat. It a pod sacs taco design one (I forget the actual name). Is it normal for the foam along the fold line to be really thin, less than half the thickness of the rest of the mat. I am assuming that this is due to compression of it being folded for a long time in the shop. Will this naturally fill out again? At the moment the mat wont lie anywhere near flat and I wouldn't like to fall on the middle section as its only a couple of cm think.
In reply to andy.smythe: I never store my mat folded, just to stop the foam deteriorating at the fold (being constantly compressed can't help can it?). I would guess shops shouldn't either.
