A spring mattress is a type of mattress that uses springs as a support system. Spring mattresses are usually composed of many metal springs, which can provide elastic support based on the pressure and weight of the human body, providing a comfortable sleep experience. Spring mattresses usually have good breathability and durability.They are widely available and come in a range of firmness options to suit different preferences.Spring mattresses also tend to transfer motion more easily, meaning that movements made by one person on the mattress can be felt by another person sharing the bed. This can be a disadvantage for couples or individuals who are easily disturbed by movement during sleep.Overall, a spring mattress can be a good choice for those who prefer a firm and supportive sleeping surface at an affordable price. However, individuals with specific sleep needs, such as those who require pressure relief or motion isolation, may find other types of mattresses more suitable.
