In public places,the parents sometimes need to use baby seats, but many public places are rarely equipped with baby seats.The "warm" design can be used to create a temporary baby seat by superimposing two identical chairs.The unique structural design ensures that the two chairs can be firmly combined when they are superimposed and this two chairs can not be separated to bring any safety problems.When the two chairs are superimposed, the baby is protected in the middle just like a parent's embrace.
