A child safety seat system having a child seat, a separable mounting plate, and a stroller frame incorporating a mounting plate. The method involves low temperature deposition of semiconductor films on inexpensive substrates such as ordinary soda-lime glass or borosilicate glass. An exemplary system includes any number of the following: a delivery device, a sling assembly, guide members, and connectors that interconnect the above. The assembly is pressed at an elevated temperature so as to melt the bonding material and the skin layers and bond the elements together.
