M&S Egyptian Cotton 230 Thread Count Fitted Sheet, Slate

Avoid if you want pure cotton

Ocado states this product is 'made in an eco factory' and that this is 100 per cent cotton. What it doesn't say is that the cotton is embedded with a chemical to prevent it creasing. After washing the sheet and trying to on a bed, it feels like lying on a heated, polyester sheet. It is now in the bin. The company that patented the anti-crease 'technology' states the the chemical in question is used in industrial processes including the manufacture of fertiliser.
