The most important thing above all is to maintain correct sleeping alignment. When lying on your side or on your back you want to maintain a straight back and spine without any pressure on neck or muscles. Have a friend, partner or better yet your health professional have a look at your alignment with you pillow to make sure that the pillow provides the support that you need. 

How often should i change my pillow?

We would suggest approximately every 2-5 years depending on the quality of the pillow. Also definitely use a pillow protector with your product. This will stop it from being affected by sweat, moisture and bacteria which are far and away the most common causes of pillow degradation. 

With so many pillows out there it is difficult to choose the right one but here is a broad chart that we thought you might find helpful to choose the right pillow. We have based our testing on a medium firmness bed. If you have a softer bed then you can look at getting a slightly lower pillow than what has been described below as you will be sinking in a little bit further. 

Position you sleep.

The other factor to take into account is a comfortable sleep and what sort of pillow you like the feel of. Obviously if you prefer a really soft pillow then you should look at adding a little height so as to maximise the support as the pillow will squash down somewhat. 

The biggest factor in deciding the size and shape of the pillow you choose is the position in which you sleep. Generally if on your side which is the most recommended the gap between your head and the mattress should be completely filled so that your neck, head and spine are all in allignment. Generally a side sleeping pillow should be a firm to medium feel so that it gives you the support that you need. If a back sleeper you need a pillow that will just give a little bit of support under the back of the neck and ensures that the head does not tilt too far forward. A softer pillow should suffice. If sleeping on your stomach then you really don't need much of a pillow at all - low and soft is the best but you should really try to start sleeping on your side or on your back as stomach sleeping will often lead to neack and spine issues down the track. 

Pillow test for head and neck support - A quick pillow check for you.to see if a new pillow will support your body.


1) Stand against or next to a wall in the same style you would lie on your mattress. Either side against the wall, back against the wall or tummy against the wall. 
2) Place your head against the wall and you will notice a gap between your head and the wall. This is the gap that your pillow is required to fill.
3) Now place the pillow between the wall and your head and check the allignment of your spine. Is it straight or is it curved and would you think you would be happy to spend the night in this position. 

The pillow that is the one for you will have you looking straight ahead with a straight neck. This will all ow your spine, neck and head to be fully supported throughout the night. 

Here is some helpful information when looking at buying a pillow and should give you a good start in the right direction.
