Synthetic Synthetic or polyester fillings are the least expensive choice and are well suited for multiple sleeping styles. However, they flatten quickly and tend to lose their shape, which means they also have the shortest life span. MicrofibreAnother popular option is the microfibre pillow, which mimics the general feel and comfort of the down pillow. It uses a fine-denier fibre, which ensures that the fill is airy, soft and silky. Microfibre is a low-maintenance pillow and will breathe like cotton. Of course, that also means the microfibre pillow will be more expensive than standard polyester fillings. CottonCotton fillings are breathable, cool and will resist mould and dust mites easily. However, cotton fillings can clump easily after a few months and may need to be replaced more frequently. You can also shop for fills that blend cotton and synthetic fibres for more durability.
