If you need extra fluff on your bed or would like it to be warmer, then you should get a pad. A mattress pad is similar to a protector, but with a few more additional features. Firstly, they will provide you with extra padding. Some pads are smart and can maintain a comfortable temperature of the bed. Having a pad will considerably increase the life of your bed. The pad will absorb a portion of your weight and delay the formation of lumps in the bed and will keep the firmness for longer. And like a protector, it can also protect the bed from absorbing moisture and prevent mite and bug infestation.
