Will the Ergo Flex pillow fit in a standard pillowcase?

Yes. The Ergo Flex pillow is a standard size measuring 65cm x 45cm. It will however perform better in a large pillowcase that provides ample room for it to mould and shape to the contours of the neck and head. All memory foam products need good air circulation to correctly mould to your body, so we recommend using a slightly larger pillowcase where possible to ensure optimum performance.
