When it comes to body pillows, there are a few things you need to take into account. First, the shape and size of your head and neck are important factors. Second, you need to think about how much pressure relief you need. Some body pillows provide more support than others, while others offer more pressure relief. And finally, consider what type of bedding you will be using with the body pillow—some pillows work better with soft sheets while others work better with firm sheets.
