It turns out that air mattresses make perfect rafts. Ours got a hole, and we ended up getting a real mattress for the guest bedroom anyway, so we decided to make good use of the broken one by floating on it down the river. We had six people (four adults, two kids) and we weren’t too sure how well it would hold all of us. Turns out it held all six of us NO PROBLEM. I paid $30 for that air mattress, and if all I ever did was take it down the river once, it would be worth every penny.
