Let's consider the type of chair
You could be thinking all I need are plastic/metal chairs. Better yet, the resin wooden chairs are more suitable
Now the table
Maybe its the round tables you prefer or is it a rectangle
Only thing left is the tent
Figuring out the size can be a little tricky. The size of tent you choose should be based on how many round and/or rectangle tables you have along with the amount of chairs. Keep in mind other key favors that take up space such as dance floor, Dj, bar, etc
