Ikea bedside table (RG4, Sonning)

This was bought to clip on the side of our son's high bed 20 years ago, was very useful as a floating bedside table. Dimensions 25x48cm, for this to work it needs to be clip over the edge of the side rail - this needs to be 2.2cm wide. Not available anymore from Ikea, hope someone can use it from pet free smoke free home
