Is it time for a new pillow? Having the right pillow is essential for a comfortable and healthy nights sleep. Finding the right pillow for you is down to the position you sleep in, your shape and your size. Pillows have a much shorter life span than duvets because they are flattened every night by the weight of our heads, which means that pillows in everyday use should be changed at least every two years, while guest room pillows should be changed at least every four years. Pillows come in a variety of shapes and sizes, and can have soft, medium or firm fillings. Most regular pillows are rectangular, but Spotlights extensive range also offers square (European) pillows, V-shaped pillows, and travel pillows.
