Best Pillows — Hollowfibre (2026)

Hollowfibre is a synthetic filling made from incredibly fine, hollow polyester fibres. These fibres create air channels that promote airflow and help regulate temperature for a cooler sleep.

Yes, generally! Hollowfibre's resilient nature provides excellent support for the neck and head when sleeping on your side, helping to maintain proper spinal alignment. However, some users may find them too firm – consider a softer option if you prefer.

Most hollowfibre pillows can be washed in warm water with mild detergent. Gently squeeze out excess water and tumble dry on low heat or air dry, ensuring to fluff the pillow regularly to restore its shape.

While synthetic fillings can sometimes retain more heat, hollowfibre’s design allows for significant airflow through the fibre channels. Look for pillows with a breathable cover material like cotton or bamboo to further minimize heat build-up.

Hollowfibre is naturally hypoallergenic as it doesn't contain any natural allergens like dust mites or feathers. However, always check the product description for specific allergen information and consider a pillow protector.

Fill power measures the density of the fibres and impacts firmness. Higher fill powers (e.g., 600-800) indicate denser, firmer pillows, while lower fill powers (e.g., 400-500) provide softer support – choose based on your preference.

All pillows will gradually compress with use and pressure. Regularly fluffing your hollowfibre pillow helps redistribute the fibres and maintain its loft. You may need to replace it after a few years of regular use.

Pillow sizes vary, typically ranging from Standard (50x75cm) to King (140x200cm). Consider your bed size and sleeping position when selecting a suitable size; side sleepers usually benefit from larger pillows.

Hollowfibre pillows generally offer good value for money, especially compared to feather or down alternatives. Prices vary depending on brand, fill power, and quality of the cover – shop around to find the best deal.

Absolutely! A pillow protector will safeguard your hollowfibre pillow from spills, dust mites, and general wear and tear. It’s highly recommended for maintaining hygiene and extending the life of your pillow.
