Side sleepers and anyone pregnant — it supports the bump and back simultaneously. The 9ft length suits most people; choose 12ft if you are taller.

Full-width support across the headboard, or placed under the knees or lumbar for extra comfort.
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.
