There are many types of side tables, the most natural variant is the trunk table. Just a stump, under bark. I like them a lot, whether they are in their original state are held or dyed in Tan. With a trunk table get you quite literally a piece of nature in the House, the wood creates a warm atmosphere.

You can buy as a trunk table, but you can also make yourself. Keep in mind though that the wood for a long time to dry. Trunk tables are fun in a group, but also alone, with another side table. You can of course let the wood or (part of) the tribe paints. Me seem these trunks best heavy, so I would make there wheels under so that they are easier to move. I find the trunk tables also very nice as a bedside table.
