Waterproof Pillowcase 48×74 cm
Waterproof pillowcase made with velvety fleece
Product description
Slide this over any pillow you own. Soft flannel fleece on the outside, waterproof barrier inbetween, completely silent, and a jersey fabric as the inner lining. It does what a $250 wedge does, and then stays on the bed, because it’s a pillowcase. A zipper in matching colour completes this latest addition to our waterproof range.
It comes in standard size (48×74 cm), which fits most pillows, and only in the colour Dark Grey.
How to wash your waterproof pillowcase?
- Wash your pillowcase on a regular washing cycle – just like you would wash your towels or sheets with a fast spin cycle
- Do not wash on a delicate cycle as it will become heavy and waterlogged.
- Select a cool or warm water setting and avoid using an extra hot water wash.
- Dry your pillowcase in the tumble dryer at the lowest setting for no longer than 30 minutes (to avoid melting the waterproof film) or hang out on the washing line in the sunshine. Please follow our strict wash instructions to avoid this.

It lifts
Any pillow, any angle. Firm for height, soft for comfort, two stacked for more. The choice is yours!

It absorbs
Oil, lotion, everything. It soaks in rather than letting it run off, and nothing reaches the pillow.

It disappears
Nobody has ever, in the history of the world, asked a question about a pillowcase.

It’s silent
No crinkle. No plastic-bag rustle. Nothing that reminds either of you that it’s there.
Foam Wedge vs Pillowcase
Wedges end up in the wardrobe.
Too obvious to leave out. Too much effort to get out. So it stops getting used.
This one never leaves the bed.
And you pick the firmness every single time. Just change the pillow inside!

Frequently asked questions
Does a pillow come with it?
No, and on purpose. You already own the right one, and you get to pick. Firm for lift, soft for comfort, two stacked for height. A foam wedge gives you one shape for life.
Will it feel or sound like plastic?
No. The waterproof film is sealed between two fabrics, so you never touch it. What you touch is flannel fleece, and you won't hear a thing.
Can anyone tell what it's for?
No. It's a pillowcase with a zip. Put a regular pillowcase over the top and it's invisible. Ships in plain packaging with a neutral sender name.
What about the rest of the year?
It's an excellent pillow protector. Period nights, night sweats, breastfeeding pillow, hair oil, a new baby, a dog with opinions about your bed. It earns its place regardless.
