When placed on the ground, the Tum&Bum will resemble a letter “L” tilted to the side or a checkmark (depending on the side you are standing on). Your child will straddle the Tum&Bum, with their bottom on the smaller section of the Tum&Bum and their chest on the longer part of it, so that they are lying on it. Their legs will naturally bend to curve around the Tum&Bum, putting them in a comfortable position to sleep.
The curved design holds them in this position, keeping them inclined throughout the night.
