Beware of black cotton when purchasing cotton mattresses

"Black heart cotton" is a synonym for inferior cotton. "Black heart cotton" does not comply with relevant national hygiene standards. Frequent sleeping on a "black heart cotton" mattress can cause harm to physical health.
Sleeping on unsuitable mattresses for a long time can affect the health of the spine, and many people's back pain and soreness are also caused by not choosing the right mattress. Many consumers believe that the harder or softer the mattress, the better when choosing a mattress. Some elderly consumers believe that the harder the mattress, the more comfortable it is to sleep, while many brands in the market are promoting soft mattresses.
So, is a mattress harder better or softer better? The reporter asked the heads of several mattress specialty stores about this, and they all said that the softness and hardness of mattresses are something consumers need to pay attention to when choosing to purchase mattresses. The ideal mattress should be moderately soft and hard, able to perfectly support every part of your body, and can evenly support every part of the body according to the curve and weight of the body. A mattress that is too soft or too hard can damage the natural physiological curvature of the spine.
