Frequently Asked Questions
Frequently Asked Questions
What is a knee pillow for side sleepers?
A knee pillow sits between the knees (and often thighs) when you sleep on your side so the top leg does not drop and twist the hips and lower back.
Why put a pillow between your knees?
It keeps the pelvis more neutral on your side, which many side sleepers find reduces hip pressure and lower-back pull versus stacking a soft spare pillow that compresses flat.
Is this a UK knee pillow?
Yes — we sell and dispatch to UK addresses with the delivery estimate shown on this page; free UK delivery applies over the published threshold.
How firm should a knee pillow be?
Firm enough to hold the gap between the knees all night without collapsing; exact fill is listed in the product details for this model.
Can I use it with a pregnancy pillow?
Yes — a full-body pregnancy pillow can support the bump while a knee pillow (or the lower arm of a U-shape) keeps the legs stacked.
What is delivery and returns?
Tracked UK dispatch and returns follow the Delivery & returns information on this page.
How do you use a knee pillow?
The pillow is placed between the knees while lying on your side. The adjustable strap can be attached to the leg to help keep the pillow in position.
Is the firmness adjustable?
Yes. The wool filling can be adjusted by adding or removing wool to suit your preferred comfort level.
What are the benefits of wool filling?
Wool is a breathable natural material that helps regulate temperature and manage moisture during sleep.
Can the cover be washed?
Yes. The cotton cover can be removed and washed according to the care instructions.
Where is the pillow made?
The pillow is handmade in the United Kingdom.
Which side should I use a knee pillow on?
Place the knee pillow between your knees when side sleeping. If you switch sides during the night, the pillow should move with you. The strap helps keep it in place. For back sleepers, place under knees to reduce lower back strain.
