Self-inflating camping mat (Emerson Park RM11)

Self-inflating mattress for camping etc. Inside is filled with sponge, so when the valve is open, the sponge wants to expand and this sucks air in. You can top up with a few more puffs if necessary. Seen a lot of use, but seem to be still functioning well. A little bigger and thicker than compact back-packing types. so pretty comfortable. I have 2 of these to go, but you don't need to take both, unless you can use both. Collection times very flexible, as we are retired. Hope you can use this.
