Last night I saw this mattress but was in too much of a hurry to stop, so thought I'd catch it on my way to work. By the time I got there, apparently the truck had started to back out but then had technical difficulties, as it was partway in the street with the hood up and a can of some sort of automotive unguent sitting on the side.
Same spot, same truck as Reappear, by the way. This site must be haunted by the mattress spirits!
