I have been trying to figure out what is cheaper, lighter and has a long shelf life between an air mattress or/and sleeping bag. The obvious use case is sleeping on the floor when on a long layover but also as an additional comforter for the first night in a strange environment as shared as being defined travel-induced insomnia or first-night effect . In both cases, having familiar smells is supposed to reduce the insomnia and have a more fitful sleep. I looked at http://1source.basspro.com/index.php/component/k2/242-camping-equipment/876-which-is-right-for-you-air-mattress-sleeping-pad-or-cot and https://www.reddit.com/r/Frugal/comments/5m74fo/frugal_bedding_air_mattress_vs_sleeping_bag_vs/ and came across two new options as well - sleeping pads and foam folding futon neither of which I am aware. I am looking for something which is 5'9 or 5'10 but dunno which of these I should be looking at ?
Can somebody list some typical brands and which of these four could/should be used while travelling. Obviously, dimensions and size along with comfort as don't want to cut things unnecessarily when travelling. Most LCC's and even full-service carriers conk out at 25-30 kgs (if they are feeling generous) where clothing takes the most place when you are travelling from a somewhat temperate climate to a more colder one.
There are two places where I hope to use either of those -
a. On the floor of an airport
b. On a cot in a room.
Looking forward to inputs.
