It excels at keeping the head and neck stable for back and side sleepers. However, its firm nature and specific geometry mean it is not a “one size fits all” solution. Prospective users should be prepared for an adjustment phase and should ensure they select the correct size (Standard vs. Midsize) to achieve the intended results.
