Recommended for side sleepers or large body types, the Night 3.0 performance pillow has a flexible foundation that allows you to comfortably sleep with your arm beneath your pillow. Featuring a unique dual chamber construction with a BOOST foam crown and BOOST foam blend, the Night 3.0 is hypoallergenic, soft and breathable and designed to eliminate pillow bounce for a deeper night's sleep. The Ver-Tex 6.0 climate control fabric cover offers a refreshing, cool-to-the-touch feel, while Air-X ventilated panels with filter fabric increase airflow while preventing allergens and dander from entering the pillow core.
