　　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.

As long as the appearance is good and there is a gimmick, it’s enough.”
