An underblanket and a mattress topper are both bedding accessories that are placed on top of the mattress to provide extra comfort and support while sleeping. However, there are some differences between these two.
An underblanket, also known as a mattress protector, is usually a thick, padded layer that is placed between the mattress and the fitted sheet. The purpose of an underblanket is to protect the mattress from sweat, dust, and other dirt. It also provides extra warmth and comfort, especially in winter.
A mattress topper is a thinner layer that is placed on top of the mattress. The purpose of a mattress topper is to provide extra comfort and support, especially if the mattress is too firm or too soft. It can also help to reduce pressure points and improve sleep quality. A mattress topper can also be used to revive an old mattress, without having to buy a new one.
In summary, an underblanket primarily offers protection and warmth, while a mattress topper provides extra comfort and support for a better night's sleep.
