Hollowfibre vs Microfibre Pillows: A Clear UK Comparison

October 12, 2026

What hollowfibre is

Hollowfibre consists of polyester fibres that are hollow in the centre. The hollow core traps air, which helps the fibre spring back after compression. Hollowfibre pillows often feel resilient and hold a consistent shape with relatively little daily plumping.

At Pillow Store both fillings appear in the range. Exact fill weights and care details are confirmed with the supplier before final claims are made.

What microfibre is

Microfibre uses much finer polyester filaments. The finer denier creates a softer, smoother hand-feel that some people describe as closer to down. Recovery can still be good, but the surface sensation is usually softer than classic hollowfibre.

Feel comparison

Hollowfibre – springy, supportive, even.
Microfibre – softer, smoother, sometimes described as “closer to feather”.

Neither is universally better. Preference is personal.

Which should you choose?

Choose hollowfibre if you want a resilient, consistent, easy-care pillow. Choose microfibre if you prefer a finer, softer surface feel. Many ranges offer both so you can compare directly.

Frequently asked questions

Is microfibre just finer hollowfibre?
They are related synthetic technologies, but the fibre diameter and resulting feel differ enough that they are marketed as distinct options.

Can both be used for side sleeping?
Yes. Firmness and loft matter more than the exact synthetic type.
