I want to get a big oak dining table and chairs. It will be used for everyday use as well as entertaining so needs to be able to stand up to wear and tear. I want it to be with us for a long time and to almost improve with age if possible. I've seen oak tables in Habitat etc but they look flimsy - I want something really solid. Are they any particular features I should ask for i.e. the finish on the wood etc? Thanks.
