I am looking for a long tv unit that I can put my tv and fish tank on.
I think the weights are approx 40-50kg and 70-80 kg respectively.

I have found one particular item I like: http://dwell.co.uk/product.php?prod=102414

However, the total weight is over the maximum load advertised. Aside
from the water/electricity danger (which I will be extra careful
about) is it ok to have my items 'slightly' over the maximum load?
