i have a memory foam pillow but it is like a brick when the weather gets cold. we don't have heating in the bedrooms. has anyone had same problem with any memory type mattresses? anyone else have one of these beds and cold bedrooms (down to 0 deg C)?

Also, when we stay at a motel and they have a good bed, i have taken the sheet back and taken a photo of the mattress label (for when i am rich and famous and can afford a really good bed).
