Pillows especially need to be the correct height and feel for your sleeping position. If you sleep on your side, which most people do, the task of that pillow is to fill the gap between your ear and the end of your shoulder. For back-sleepers a shallow pillow is recommended so it does not push your head up out of line with your spine. Front sleepers should have very shallow pillows so as not to push up your head again causing misalignment of the spine.
Pillows come in all types of filling and Waterlooville Beds have a variety of cooling and supportive pillows on display. These can also be used not only as a pillow but to lay your arm or leg over as a cooling tool for injury and muscle damage.
Please bear in mind new pillows can alter your posture and it may take a couple of nights to adjust.
