How long does it take to adjust to a new pillow?
Most sleepers require between 3 to 14 nights to fully adjust to a new ergonomic shape. During this time, the body recalibrates to the new alignment, and the memory foam softens slightly to match the user’s weight.
Are there downsides to cervical pillows?
The primary downsides include a lack of versatility for different sleeping positions and the potential for increased neck strain if the loft is too high or too low for the user’s frame. They also tend to be less “huggable” than traditional pillows.
