This is a great piece of wood measuring 45" x 70". It was made specially to go on my Dining table so that more people could sit round it. On the back it has Four pieces of wood which clip onto table. They can easily be taken off and refitted to fit any size table. At the moment they are on place to fit a table measuring 29.5" x 60". This is a great way to extend a table when needed. It is very heavy and will need two people to lift it on
