Airsprung mattress 4' 6" very clean (West Malling ME19)

This Airsprung regular-sized double mattress is in very clean condition, as it's always been covered by a mattress protector. It's been used by one person for 9 years. If a mattress topper is placed on top it probaby has a couple more years of life. (Current user is replacing with a memory foam mattress.)
