I bought this last year for my motorcycle camping trip, but it just proved to be too bulky for the bike in conjunction with carrying the tent, and all the other stuff I needed. Used it for one trip. It gave me the best nights sleep I've ever had whilst camping.
It's sold by Go Outdoors for £70.
It is a self inflating mattress, so all you have to do is open the valve and leave it alone whilst it inflates. You can top it up if necessary. Then close the valve. Very simple.
As new. Postage is extra
