Designed by Chiropractors specifically for the Back Sleeper, The Slumberlicious™ pillow has a 4″ indentation in the center which cradles the back sleeper’s head while offering gentle support under the neck. The under neck channels offer two slightly different widths to accommodate longer or shorter necks for the perfect support for each individual. Each pillow is hand made for you in Texas, USA. The Pillow Bar's Down Alternative fill contains a proprietary blend of combed polyester fiber designed to mimic the luxurious density and loft of naturally-sourced down. Includes a removable 300 thread count washable cotton sateen zippered protector.
