Unused cot mattress 70 x 100cm (Perry Vale SE23)

This mattress came free with our cot, but we’d already bought a better mattress to go in it. Although it’s never been used, it’s been in our loft for 4 years. Could be used for a baby if hoovered and cleaned, or could be used as a dog bed. I thought about using it as a bench seat but it’s not quite the right size.
