This coffee table is made of elm that I managed to scrounge from a joiner friend of mine. He reckons it's been kicking around his workshop for at least 20yrs!! The base is an elongated version of Richard's side table and it is approximately 800mm x 500mmx450mm. I think this is about the maximum size using the dimensions of the side table. Beyond that I think there will be too much flex in the frame so thicker dimensions would be required. The top is two colour resin (Green and Black). I also made some coasters to go with it.
