Mattress Comfort
Concerning mattresses, "comfort" refers to the way the surface of the mattress feels beneath your body. Mattress companies most commonly describe comfort in the following terms: Pillow Top, Eurotop, Plush, and Firm.
Pillow top is the most common type of mattress surface. It is a thick, soft, attached layer that covers the entire surface of the mattress. This layer can be made of foam, cotton, wool, or other fibers. A pillow top mattress provides the comfort you need with a cushioned softness similar to a featherbed.
Eurotop mattresses are similar to pillow tops but have the additional padded layer sewn more firmly to the mattress, rather than the gusseted featherbed design of a pillow top. The gentle cushioning found in a Eurotop mattress may be preferred by people suffering from painful joints.
Plush mattresses provide an added level of comfort through extra cushioning. They are a great choice if you and your partner differ on your mattress firmness preferences. A plush mattress is more padded than a firm, but not as cushioned as a pillow top or Eurotop.
Firm mattresses generally do not have any extra padding on the surface. The mattress is comfortable, but not plush. People with lower back pain often prefer beds that are firmer, stating that the firm padding prevents their body from sinking into an uncomfortable position.
