床垫坚定是床垫的支持吗？
firmness and support are related but separate factors to consider when choosing a mattress. mattresses that are too soft will not offer the correct amount of support, but choosing a firmer mattress doesn’t necessarily mean it will be more supportive. in fact, a too-firm mattress can be unsupportive if it fails to allow for the natural curve of your spine.
to determine the best firmness for your needs, consider your weight and preferred sleep position. instead of increasing your mattress firmness past this level, consider a bed with a robust support system — such as an ergonomically zoned hybrid mattress — if you require more support.
杂交种 mattresses combine a thick polyfoam, memory foam, or latex comfort system with a coil support core. this coil core can be similar in design to an innerspring, but the most common and popular models now use pocketed coils — fabric-wrapped coils that can compress individually for improved support and durability as well as reduced motion transfer.
旨在嫁给泡沫和内林床的最佳品质，混合床垫往往在支持，温度调节和减压等重要领域表现良好。然而，各种各样的混合设计确实意味着各个床垫可以非常不同地执行。大多数人可以找到一个符合他们的需求的混合床垫，但并非所有的混合动力车都是一个不错的选择。
