A pillow top is a layer of extra padding sewn on top of the mattress comfort layer. This extra padding can be made of cotton, wool, foam, or other plush materials. Euro tops are sewn under the mattress cover, while regular pillow tops are sewn on top of the mattress cover. That means a Euro top will offer a more luxurious look than a standard pillow top.
Either way, a pillow top is an extra layer of luxury that doesn’t cost a whole lot extra. It will give you more cushioning and pressure relief without changing the overall support of the mattress. So a mattress with a pillow top could be a good purchase for you, especially if you want your bed to have a luxe feel.
