Achieving restful sleep starts with selecting the right pillow, particularly for side sleepers who need extra support to keep their spine aligned. A well-chosen pillow can prevent neck and shoulder pain and enhance sleep quality. Here are the top 9 factors to consider for finding the ideal pillow for side sleepers. 1. Loft and Thickness The loft, or height, of the pillow is essential. A pillow that's too thin won't offer sufficient support, causing misalignment, while one that's too thick can strain the neck. Ideally, choose a pillow with a medium to high loft—around 4 to 6 inches—to ensure proper alignment of the head, neck, and spine. 2. Firmness Firmness affects support and comfort. Side sleepers generally need a pillow that maintains its shape throughout the night to prevent sinking and misalignment. Look for a balance between firmness and softness, providing enough support while still being comfortable. 3. Material Material greatly impacts comfort and support. Opti
