It hasn't been an issue for us. We spend most of the cooking and eating time outdoors but the few times we have had to eat inside (family of 5), it has not been a problem. In fact it makes leaning in the door to pass food back and forth easier. On the odd rainy day, we also put the table down or take it out, and use the dinette as a large couch/bed for the kids to watch a movie. The lack of the back rest also helps in that scenario.
