Identification of Memory Cotton Pillow, also known as Memory Pillow, is made of polyurethane material and has viscoelastic properties. It can automatically deform according to the position of the head and neck, ensuring a tight fit between the pillow and the neck at all times. Its prominent feature is that it fixes the head to prevent it from slipping and falling off the pillow.
Memory foam pillows can absorb impact force, and the skin does not feel any pressure when placed on them; It is designed according to ergonomics, with the ability to memorize deformation and automatically shape the head, which can fix the head and prevent the occurrence of pillow falling; The ability of automatic shaping can appropriately fill the shoulder gap, prevent air leakage in the shoulder area, and effectively prevent cervical spine problems. Memory foam pillows can prevent bacteria and mites, and slow rebound sponges effectively prevent mold growth. They are particularly effective in repelling mold growth and emitting stimulating odors. Memory foam pillows are also breathable and moisture-absorbing because each cell unit is interconnected, providing excellent moisture absorption and breathability.
Memory foam pillow identification
1, Production process. Memory foam pillows come in two styles: molded memory pillows and cut memory pillows. Molded memory pillows are made using a series of processes such as adding additives, foaming, and mold pressing. They have a higher density than cut memory pillows, usually around 70-100D, and have a better hand feel. Cutting memory pillows is actually purchasing finished slow-rebound sponge pillows and cutting them into the shape of the pillow. As the molding process relies on cutting rather than adding additives to the mold, no other additives are added inside.
2. Texture and temperature sensing. High-end memory cotton pillows have strong temperature sensitivity and can become soft or hard according to changes in temperature. Handprints can be seen without applying pressure when placed on them. The high-end memory cotton has a comfortable feel, and it feels like kneading dough when pinched. Memory pillows with slightly lower quality either feel a bit stiff or stiff.
3. Press the rebound time. The suitable rebound time for memory foam pillows is about 3-5 seconds. Too short a time does not have a slow rebound effect, and too long a time can cause the body to stiffen. Many consumers mistakenly believe that the longer the rebound time of memory foam pillows, the better the quality, which is a misconception.
4. Pillow lifespan. The quality and service life of memory foam pillows are directly related to whether they are made of pure polyurethane. Pure polyurethane does not deform for more than 5 years. If raw materials such as talcum powder are added to increase density and weight, the quality of the pillow will be greatly reduced, and the service life is generally only 1-2 years.
