If you tend to sleep on your front, we would suggest a medium fill pillow. You want something slightly softer if you are resting your face on the pillow. If you prefer to sleep on your back, choose a firm pillow to support your neck and head. A floppy pillow could give you a neck ache. Side sleepers it's really up to you. A medium or firm option will work just fine, it's just down to preference really. Please have a quick read through our Bedding Buying Guide for more information about pillows.
