Sleep Position Hub
The Complete Side Sleeper Hub
Side sleeping is the most common position — and the most punished by the wrong mattress. Shoulders and hips need to sink while the lumbar stays supported. Get the firmness wrong and you'll wake up sore even on a $3,000 bed.
Take the Pillow QuizBody weight is the single biggest variable for side sleepers: under 130 lb usually wants Soft to Medium-Soft (3–5/10), 130–230 lb wants Medium (5–6/10), and 230 lb+ usually wants Medium-Firm (6.5–7.5/10) with reinforced edges. Pillow loft has to match — most side sleepers need 5–7 inches of loft to keep the cervical spine neutral.
Use this hub to find picks tested for your weight class, body type and shoulder/hip sensitivities, plus the pillow guides that fix the other half of the alignment problem.
