How to choose a slow rebound pillow? Slow rebound pillow, also called memory foam, is a temperature-sensing and pressure-relieving material. For some office workers who work in an office for a long time, slow rebound pillows can support their necks and heads well, allowing office workers to have a good sleep.
1. Rebound time
How to choose slow rebound pillow
Many Consumers think that the longer the slow rebound pillow lasts, the better. In fact, this is a very wrong idea. The slower the rebound speed of a slow rebound pillow, the smaller the kinetic energy released after absorbing external force; the longer the rebound time, the better the ability to match the user’s body shape. The slow rebound time of real memory pillows is between 10 seconds and 20 seconds. If it is too short or too long, it will not achieve the slow rebound effect. Therefore, many domestic brands cannot do this, and only some European and American brands can do it.
2. Feel and temperature
How to select slow rebound pillows
The main feeling is hardness and slow rebound speed, as well as a greasy, moist feel. Generally speaking, the relationship between feel and density is not very big. It mainly depends on the craftsmanship of the slow rebound pillow. When the ambient temperature changes a little, the hardness can change significantly. It becomes harder in winter and softer in summer. This is a drawback of slow rebound sponge. A truly good slow-rebound pillow feels very comfortable, like dough that has been kneaded evenly.
3. Density
Slow rebound pillow density
Density is the basic indicator of slow rebound material One, high density means thicker walls, smaller cells, and resistance to fatigue damage. It also has minor disadvantages, including reduced air permeability, reduced thermal insulation, and increased temperature sensitivity. Due to technical bottlenecks, the density of domestic slow rebound pillows is generally lower than 100D. Sometimes different formulas, processes and raw materials will cause slow rebound pillows of the same density to vary greatly. When consumers purchase, they only need to choose the appropriate density according to their own needs.
Four. Product Technology

Slow rebound The main manufacturing process of elastic pillows is cutting and molding. Cutting is to first make large slow-rebound sponge blocks and then cut them into pillow shapes. Because there is no external pressure for large-volume slow-rebound sponge foaming, it is difficult to control the opening of the cells, and it is easy to collapse when the density is high. The molded ones are made by adding additives to the mold through a series of processes such as foaming and mold pressing. Due to the addition of other additives, including chemical additives such as foaming and softening, it feels good.
5. Brand
There are many brands of slow rebound pillows on the market, but due to technical reasons, it is recommended that you try to choose a more formal one, which has safety indicators and a relatively mature production process, but the price is relatively high.
