car seat (Vinita)

I am looking for a car seat for a 2 year old. I have my god son a lot and I cannot afford to buy him a new one. He has one but it's not safe. Yes it buckles him in but it has no padding so he sits on just plastic. The plastic gets hot and I can't put him in it. His parents are separating and his mom is still trying to find a place to live for them so she can't afford to get him one. Please I don't care the color or even how it looks. I just want him to have a car seat that is safe for him. Thank you
