A novel microporous crystalline silicoaluminoaluminophosphate molecular sieve framework, having in its as-synthesized form, an X-ray diffraction pattern including the lines listed in Table 1, and method of its synthesis using 4-dimethylaminopyridine as organic templating agent in fluoride medium under microwave-hydrothermal conditions. The first opening has a first edge portion on a first direction side and a second edge portion on a second direction side, the first direction corresponding to a scan direction and the second direction being in the opposite direction to the first direction. The carrying bag has at least one storage compartment, a top strap adapted fit over the retractable handle of the booster seat, and optional side straps adapted for securement to the arms of the booster seat. The mounting structure is constructed and arranged to mount the main body on a belt-line region of the motor vehicle door.
