Somnia 5.5 Pillow - Large Side Sleeper SupportMaximum height for larger side sleepers Hi there. Dorothy here from Mattress Miracle. The Somnia 5. 5" is my recommendation for larger side sleepers or folks with broad shoulders. After 37+ years helping people find the right pillow height, I know that bigger people need more height to keep their neck properly aligned. Why 5. 5 Inches Works for Larger Folks If you have broad shoulders or are a larger person, regular pillows just don't give you enough
