I don't really know what to look for to be honest, but the well reviewed baby car seats are too expensive to be imported here. Is there any safe brand available on lazada? thank you

One option is the Joei brand. It's imported from the UK, is well regarded and reasonably priced. Rear facing, which is good.

 

They have a base that fits into the car (isofix) and a seat which clicks in and out of the base for convenience. It's really handy because if your baby falls asleep in the car you can unclick the seat and take baby inside the house in the seat without waking them up. That's a real bonus.

 

Seat here.

 

Base here.

 

If you are in Bangkok that particular seller will send same day by Grab delivery for no extra charge. If you ask nicely they will probably throw in a free Lanco rubber toy aswell (I like a bargain).

thanks black cab that looks solid! I will look into it more, hopefully they ship up to chiang mai!

They ship outside of Bangkok using Kerry.

Raised my kid the Isaan way, or maybe it's the Thai way, no car seat. His mother held the baby till she was old enough to crawl around the truck.
