How Heavy Is a Marble Coffee Table? Weight Data for 80 UK Models & Floor Loading

A marble coffee table weighs more than buyers expect, and the figure can be calculated rather than guessed. Using an accepted marble density of around 2,700kg per cubic metre, Furniture in Fashion sets out derived weights by size and thickness: a 120cm by 60cm top at 20mm comes to roughly 39kg, and the same top at 30mm to roughly 58kg before any base is added. We did not weigh 80 models and no published UK dataset exists, so nothing here is presented as a measured sample. On floor loading, the report finds that domestic floors built to the imposed load requirement in BS EN 1991-1-1 are untroubled by a coffee table, and that the genuine risks are point loading from a narrow base on suspended timber floors, indentation of soft finishes, and the diagonal clearance at the turn of a terraced staircase. Practical guidance covers base width, protective pads and the two person lift most tops require....
