The first thing you'll notice once you pick up this aromatherpay neck pillow is the weight. It's H-E-A-V-Y.... and that weight relieves tension in the neck and shoulders in ways that pint-size synthetic-filled neck pillows can't. It's filled with an all natural blend of grains (including flaxseed) and lavender flowers that's been infused with lavender essential oils. Flaxseed's natural oils help make the lavender essential oils last longer and help make the pillow retain heat and cold longer. This neck pillow's intense lavender aroma will send you into a state of bliss! Put it in the freezer for a cold compress or the microwave for a hot compress...as this neck pillow has no styrofoam or artificial fillers, it's microwave safe, and won't release harmful pollutants or chemicals if microwaved. Our all-natural lavender neck pillow is the ultimate in aromatherapy relaxation! 72 oz.
