Ereada Corp is an American company introducing high-end products. Our company focuses on Far Infrared Amethyst mats and pillows with many benefits.We have four collections of electric-powered Infrared mats: Classic Rich Brown hot crystal mattresses, Photon Bio-Stimulation Purple mats,Gemstone mats and Gray ones. Ereada SOFT FIR Amethyst D-shape Semi Roll Mini Pillow Bolster is 14.5"L x 6.5"W x 3.2"H with roughly 1.5 pounds of Amethyst, Green aventurine, Black obsidian, Black tourmaline, Garnet, Red agate, and Tiger eyes. Gems are infused into a detachable pad 18"Lx16"W which you can use separately from the foam insert. A clear film vertical line shows Gemstone crystals, abundant under the whole wavy surface. The cover is made from high-quality, durable suede, soft and pleasant to the touch. The pillow provides proper neck support and keeps your head elevated and cool during heat sessions. You can use it under the knees as well. Crystals recapture Far-infrared heat from the Amethyst Mat and radiate it at a lower intensity. It is particularly beneficial when using the mat for shorter periods at high heat levels. Non-Electric Pillow naturally releases Far-infrared Rays and Negative Ions delicately. The pillow usually does not demand a long adaptation for sleeping and relaxation. However, if the foam insert is too hard, you can remove it and use the detachable pad with crystals on your regular sleeping pillow. Gemstone pillow helps to create an optimal setting to relax and fight occasional sleeplessness, get rid of stress, blue feelings, and occasional sleeplessness. It is excellent for both beautification & wellness. Ereada Gemstone Pillow is an exceptional addition to all mats and heating pads, definitely recommended for use in both home & and professional settings.
