memory foam and cut to a contoured curve, so the thickest part sits against the small of the back. The cover is a soft fabric with a zip down one side, and a woven label sits at the centre of the face. The cushion measures about the width of a chair back, which lets it sit flat against an office chair, a car seat or a sofa.

Never put the foam in a washing machine or on a radiator, because heat distorts it and it will not come back to shape.
