For cutlery and dishes, one probably wants extras anyway to buffer for those days when they couldn't yet wash the previous day's dishes because they were too busy. We've all experienced it. Probably don't need guests to bring cutlery and dishes. But chairs? Probably no need to have personal buffer for chairs ever. And I'm not sure asking guests to bring their own chairs is the answer when guests come. Does everyone need to go buy folding chairs to be a houseguest now? How do hosts guarantee that the chairs would not damage specific carpets or hardware floors? Etc.
