Camping mats (Rhydycroesau SY10)

I have 2 foam camping mats which are very old and patched up with gaffa tape. I used to use the two taped together. The other is an Outwell mat that also used to inflate until the valve leaked. It can still be used as a thin mat and is unmarked and only used a couple of times. They might have some other use other than camping mats so thought I'd put them on here before taking to the tip.
