Ergonomic pillows are often worth the investment for individuals who wake up with localized discomfort or stiffness.

Memory foam can improve comfort by contouring to the specific shape of the head and distributing weight evenly. However, some users find they retain too much heat or provide a “stuck” feeling, leading many to prefer fiber-filled ergonomic options like the Tri-Core.
