Frequently asked questions

What size is a standard UK pillow?

50 × 75cm — all our standard, quilted, stripe, box and duck feather pillows are this size.

Why has my pillow gone flat?

Filling compresses with nightly use and moisture; plump daily, air weekly, and replace roughly every 1–2 years for synthetic fills.

How many pillows should I sleep on?

One supportive pillow that keeps your neck aligned beats two flat ones stacked.

What pillowcase fits a V shape pillow?

A dedicated V-shaped case — standard cases don’t fit; we sell the V pillow with a case option.

Are feather or hollowfibre pillows better for allergies?

Hollowfibre is generally the safer choice for allergy-prone sleepers and washes at home more easily.
