A gap is provided at a prescribed location along the seam to accommodate and air tube. The portion of the air tube received in the gap has a generally diamond shaped cross section including a central tubular region and opposed lateral side sections that taper radially outwardly in order to occupy correspondingly shaped regions of the gap. The shaped end of the air tube is sealed to the facing cell layer material to provide an airtight, unstressed seal therebetween.
