Double self inflating camping mattress (Hanover BN2)

Outwell Dreamcatcher 7.5cm
This is comfortable and still functions as a mattress. However it has a slow leak somewhere meaning it will not stay deflated which makes it tricky to transport easily. We've been using it to top some lumpy seats when we sleep in our van, we've also used it on the ground and it's fine though needs topping up each night.
