Bear in mind that should you decide to use normal furniture to handle an aquarium and that furniture fails as a result of prolonged accidental water spills and/or just the sheer weight of the aquarium, it is very unlikely that the warranty on the aquarium will be honoured if it gets broken and your home contents insurance are unlikely to pay for damages to the piece of furniture, flooring and anything else that gets damaged.
Read the small print on your contents insurance or call your insurer before going for a larger aquarium with normal household furniture cos if the aquarium does go and it takes everything around it too, you will be out of pocket for what could be very expensive repairs to your home
