The pros and cons of memory foam pillows are roughly as follows:

Pros: Conforms to the contours of the head, quiet and silent.

Cons: May produce harmful gases initially, temperature, expensive, too hard for some people, high sleeping temperature, and heavier than average.

Next, let me talk about the disadvantages of memory foam:

Memory foam has poor elasticity, so it cannot provide support. Therefore, when buying a memory foam mattress, you must pay attention to the support material under the memory foam, because the lower layer provides support. The support of the mattress ensures that the spine is in the correct position during sleep.

Similarly, you cannot choose a single memory foam mattress, which is very common in the currently popular compression roll-up mattresses. Considering memory foam as "support" rather than "pressure relief" will lead to a very bad experience.

Memory foam does not provide good spinal alignment for people with certain weight distributions and/or different sleeping positions. Memory foam also softens and causes you to sink during the night, which makes it difficult to maintain a natural spinal position without support material underneath the foam.

If the spine is not relaxed in its natural position, the muscles will contract and work to return the spine to the correct position. The muscles are tense all night and do not get rest. This is why you wake up with back pain in the morning.

The pure memory foam compression roll mattress originated in foreign countries. In recent years, some Internet-born companies have learned this and are trying to subvert the industry. Ignoring the supporting materials under the memory foam, such as polyurethane foam and latex, there is only one purpose: low material cost and low packaging cost.

In the early years, there was a junior girl in my company. She was a fine arts major, very hardcore, and had great artistic skills. Later, she went to xx company to design mattresses... I asked her, "How can you, a painter, pretend to be a product manager in a big company? Is it tiring?" She said, "No one cares. As long as the appearance is good and there is a gimmick, it's enough."

Affected by temperature

Even the "non-temperature-sensitive memory foam" on the market now will change in hardness and softness according to temperature changes, but the change is small, not non-existent.

Due to the temperature of the human body during sleep, fever will definitely occur during sleep, and the memory foam will definitely become soft. You will "sink" to a certain extent, which brings us back to the support problem mentioned in the previous point.

Due to temperature sensitivity, indoor temperatures that may make a mattress "too hard" or "too soft" in some cases, or climate changes, the complexity of the situation makes it difficult to decide whether a memory foam mattress is right for you.

Heat dissipation problem

All foam materials have heat dissipation problems. Memory foam is probably the foam material with the worst heat dissipation. Even the "new generation" memory foam that is sold as breathable is not as breathable as latex and other materials with "open" cell structures.

Response time

The slow rebound feature of memory foam is both an advantage and a disadvantage. The slow rebound effect takes more time to adapt to different postures. If you are not a good sleeper and often change your sleeping position, this may have a great impact on you. Different types of memory foam take time to adapt to your sleeping posture and body contours.

You must have seen the animated pictures or videos of memory foam slowly rebounding. The merchants deliberately emphasize the characteristics of slow rebound, but completely expose the long response time. The memory foam has different formulas, different response times, and different rebound times at different temperatures.

Environmental issues

Environmental issues are both a problem and not a problem. Any foam material will have some chemical processes in the production process, so the control of volatile compounds (VOCs) has also become a major disaster area for environmental protection.

If the foam in your mattress is certified by Certipur or Oeko-tex (or similar organizations), you can be assured that it is your best choice. Temperature and humidity will accelerate the aging of any foam material, especially memory foam.
