Santa has a really hard job to do with delivering presents to the good boys and girls all over the world in one night on his trusted reindeer. As parents or grandparents you can make his job easier by making sure the children get off to sleep as soon as possible and this can be done if you use a memory foam mattress. Once the children are tucked up on these mattresses they will fall asleep, even though they will be so excited.
This will allow Santa to either climb down the chimney or through the front door if access to the chimney is not available and allowing him to visit all the other boys and girls easier as he won't be have to worry about waking up the children.
