Already several folding mattresses at home that were not worth the money. Tchibo to furniture store, all the same. For children the cost parts like in the price segment 25 be sufficient for adults definitely not. My guests are as well as possible with us to stay, a guest room is not in it, so is the 1st choice Gigapur folding mattress. Well, she smelled something, but this is now solved by airing out. Surely you do not sleep directly on the mattress. Who is sleeping directly on is your own fault. I bought 2 mattresses, so is a comfortable width available. Furthermore, I always put a pad Molto on how I handle it in my bed and on top of that comes a fitted sheet. This, and the Molto edition in 1,60x2,00 keep the mattress together perfectly and the sleeping comfort is perfect. So my guests feel at home and my children use the pieces to play during the day. Conclusion: The purchase was worth it, would never buy more cheap mattresses and visco-side one recognizes even without knowing on which side it is located. Would you immediately buy quality, you could save the money for cheap parts. The endurance test has passed the way. As well as several adults, and I have already slept for nights out. No one complained of back pain or odors. The best folding mattress that can be had in the market.
