There are four types of construction... I-Beam construction is characterized by parallel vinyl beams oriented vertically or horizontally. Coil Beam construction is differentiated by open loops of vinyl, each attached by a weld (typically circular) at the top and bottom of the bed. Wave Beam is a converted I-Beam construction consisting of equally distanced air channels creating a wave like surface. Comfort-Top Construction is Two Layers. It has an I-Beam base and a top layer of circular imprints attached by a weld to a solid sheet of vinyl providing flexibility.
