Oak has traditionally been used in the construction of dining tables due to its resilience and capacity to withstand heavy use over an extended period of time. Another benefit of oak is its patterning, which is another reason it is used so often in table manufacture since it accentuates the lovely wood grain. As a result of its high level of hardness, it is ideal for use in a household with children and pets. If, on the other hand, you have your eye on a recovered oak dining table, you will be making a purchase with an awareness of its impact on the environment.
