The butterfly memory foam pillow: is it right for you?

A contoured foam pillow that keeps its shape all night, with a cooling cover you can wash. Not for anyone who loves a soft, squashy pillow.

The bottom line

Worth a try if your pillow is flat by morning or bunches up. Give it two weeks, and use the 60-day returns if it doesn't suit you.

Good for

Back sleepers who want the head and neck cradled. People whose pillow goes flat overnight. Warm sleepers who want a breathable cover.

Skip it if

You love a soft, fluffy pillow, you sleep mostly on your side (the seller makes a separate side-sleeper model), or you live outside the US.

Why it's different

A butterfly shape

A dip in the centre holds your head. The raised edge sits under your neck, and the wings leave room for your shoulders and arms.

Foam that holds its shape

Solid memory foam moulds to you and springs back. It never clumps or goes flat like fibre filling.

A cooling, washable cover

A breathable, moisture-wicking cover offsets foam's tendency to hold heat, and it goes in the washing machine.

Any new pillow at a new height feels strange at first. Most people need a week or two to get used to a contoured one.

Questions

Does memory foam sleep hot?

Solid foam holds more heat than fibre or down. The cover is made to breathe and wick moisture, which helps, but if you always sleep very hot, weigh this up.

How do I clean it?

Unzip the cover and machine wash it cold on a gentle cycle. Don't wash the foam. Spot clean it with mild detergent and let it air dry out of direct sun.

Does new foam smell?

New foam can have a smell at first. Airing the pillow for a day usually clears it.

Where do I buy it?

From the seller's official store, through the buttons on this page. We don't sell it ourselves. The seller handles payment, delivery and returns.
