Car safety - children car seats (Manila)

Hi, our family is relocating to Manila in July. Having two children at ages 3,5 and 2yrs, they need to be in children car seats.

Anyone here with recommendations of bringing car seats from home, compared to buying in Manila? The family counts six (7 including the driver) and we will be driving a 7-seat SUV.

If buying locally, which seats are available, and where? I noticed Landmark having a section with strollers, car seats and more, but not the brands.
