I have a nearly new orthopaedic mattress which fits an Ikea day bed or other narrow single bed. It measures L200cm x W82cm x D22cm. No marks or stains. It is a Tender Sleep Galaxy Ortho mattress bought as my daughter was getting back ache with the standard Ikea mattress. She now has a new bed so we don't need it.
