The inner structure of the table, from wich the glass will be suspended is made in MDF in my replica. If anyone has the intention of constructing one, I would recommend a less dense wood, since MDF is extremely heavy. It was 19mm thick MDF, i think. I bought it at C/Madera in Madrid City and it was quite cheap. So after taking all these to home (the hardest part) I verified the dimensions of all the parts joining the elements with adhesive tape.
