I was that I need looking for a double mattress for my rather uncomfortable sofa bed. Since my apartment is more of a storeroom (27 sqm) was for me only a foldable, space-saving mattress in question. Unfolded, it offers enough space for 2 adults in my opinion. The uncomfortable groove in my sofa, on which I rested it on the wood with a .. while sleeping is überpolstert now some mass of this mattress. In any case, the sleep has improved on my couch to multiples. The great thing is: unfolded almost 1,30m wide and the part can be transformed into a compact cube seat, which can be very space-saving daytime stowed or can be placed beside the bed. Very thick the mattress is not that could have been even bisserl thick when unfolded. But me and my girlfriend it enough yet. Only for very obese people (150Kilo or so) the folding mattress could have too little padding. Mind you not as a single mattress. Individually it is almost 14cm thick, and that's great. The price in my opinion is still almost 75 Euros a bit high (with shipping). However Doppelfalt (folding) mattresses rarely find what moved me to ordering this very copy. 4 stars there are, 1 star deduction for the relatively high price and the low bit padding of 6.5cm.
