Super disappointed in this! My kids cannot play with this it’s fall apart on the top layer. Will be returning or asking for replacement

Bought this for my very active 6 year old grandsons birthday. It is going to help him guide his patience to be steady and balance upright. He will want to beat the time of his 3 siblings on it as it looks so fun they all will want to be playing with it! Great active plaything since they can't be in school this year!
