Type: The texture and fullness suggest it is a memory foam or microbead-filled neck pillow, offering firm yet conforming support. This is a common type used for resting during travel or while sitting at home/office.
Design: The pillow is covered in a soft, plush material (such as velour or fleece) in a deep navy or royal blue color. It has a snap or clasp at the front to secure it around the user's neck, preventing it from shifting. There appears to be some white embroidery or lettering on the side.
Purpose: Its primary function is to provide ergonomic support to the neck and head, helping to prevent stiffness and discomfort when sleeping or resting in an upright position.
