Hotel Collection Luxurious Cotton Pillows 4 Pack from Snuggledown offer soft, gentle neck support thanks to their non-allergenic cluster fibre filling. In 100% cotton covers they're machine washable and can be tumble dried, and they won't lose their shape either - just re-plump after washing. All our synthetic pillows and duvets are non allergenic, which means there's nothing in them that could cause allergic reactions. Which is great for peace of mind and essential for allergy sufferers.
