I love swings, especially when they are indoor! A couple of years ago my boyfriend and I installed a swing that he made for our artist loft in Boston. We use it daily as a seat, as natural air conditioning during the hot Boston summers, and it is always a hit with guests. We can easily move the furniture, which gives us the ability to fully swing (even do the underdog!). Ever since we put it in I am aware of all the different types of swings out there. Here is one that is made out of retired wine barrels found on UncommonGoods.
