Big dipper neng' an safety seat

Safety seats can definitely be installed, but they are fixed in different ways.

The Big Dipper has no safety seat interface and can only be used when the seat belt is fixed.

But if the child is over 4 years old, it is good to have a seat belt length adjustment belt on Taobao. Their model C product suits you very well, because it can hold the seat of the Big Dipper. The biggest advantage of that thing is that it doesn't take up space.
