Mattress - small double (Craigleith EH4)

This is a John Lewis Essentials mattress bought in 2019. 1,000 pocket springs. It is a small double - measures 180x 130 cms . Is still under a 7 year John Lewis guarantee. It has some marks which I’ve tried to show in the photos but it has always been used with a topper. Only stopped using it because it doesn’t fit our new bed.
