3D pillow refers to a new pillow made of 100% 3D stereoscopic fiber (commonly known as 3D spacer fabric). It overcomes the shortcomings of traditional pillow core materials, such as non-washable, airtight, mildew-proof and moisture-proof, and shows strong advantages in elasticity, support and compression resistance. This is a breakthrough product. The dual support of 3D dense pillow can firmly support human cervical vertebra, thus dispersing the pressure of cervical vertebra, and even patients with cervical spondylosis can easily sleep soundly.
