A single mattress - Sofia Open Coil and Memory Foam Mattress. Bought 5 years ago but not regularly used.
It does have a couple of drink stains on it but otherwise is in very good condition.
I also have a double mattress to give away which is 5 years old. Silentnight 3 Zone Memory Foam Mattress.
This one has been used more regularly and also has some stains. But it is good condition. I don't have a photo as it's wrapped in plastic following a move.
