C.S.
Crib tent is my vote. He is just to young to stay in a bed and he'll be roaming the house in the night and end up getting hurt. I used a crib tent for my now 5 year and it worked great. As for the chairs on the table, just a suggestion on that too. We used bungee cords under the table around the legs of the chairs. It seems safer then possibly having a chair pulled down on a little head. It was a pain to get under there a few times a day but worth it. Good Luck!
