A place to crash can refer to a variety of locations, such as a SOFA, a PAD, or an INN. A SOFA is a piece of furniture typically used for seating, with cushions and upholstery. A PAD is a flat, cushion-like object used for sleeping, often made of foam or other materials. An INN is a type of lodging, usually providing meals and other services. All three of these places can provide a place to crash for a short period of time.
