Quick Answer
The pillow sleeping bag—a specialized ergonomic pillow designed to cradle the head and neck—is an emerging sleep accessory aimed at improving night-time alignment. It is most suitable for side and back sleepers seeking structured support. However, its primary limitation is its highly specific shape, which may feel restrictive to active sleepers who frequently toss and turn.
What Is a Pillow Sleeping Bag?
