We love our table!! It's very solid, with that being said- we use it with the leaf and it's just big enough for 4 chairs. I do not recommend having intentions of anything else (I.e using the leaf as an extension to fit 6 people) 
We are very happy with our purchase, it came very well packaged and on time (5 boxes) my husband was able to put it together without any help very quickly! For the price you can't beat it
