- If it’s a feather or down pillow, place the pillow on a table, fold it in half and squeeze out the air. Let the pillow go and if unfolds itself back to its original shape then it means the filling still has enough support in it. If it doesn’t spring back then it’s lost its support and needs replacing.
- If it’s a synthetic pillow (polyester, hollowfiber, microfiber) then place it on a table, fold it in half and place a small weight on it, around 300g (e.g. a decent paperback). If the pillow springs back to shape whilst flinging off the weight then it still has enough support, if not, chuck it and buy a new one.
