infant care chair

Hi I have two questions.
1)Firstly does anyone have a picture of the infant care chair that they can share or point me in the direction of a picture.
2)Does anyone know if the seats have to be positioned on any particular seating area of the aircraft in economy. We have pre-assinged seats on the ABC side of the plane but I'm hearing that they can only be posiioned in the middle of the aircraft or on the HJK side..
Any help would be greatfully recieved
