The mattress comes small wrapped in foil wrapped around the house. If you removed the packaging accommodates a no smell. The mattress rolls apart and after a day time spent it is completely smooth. The outer cover is totally soft and comfortable. Feels almost like silk. I have the mattress are in day bed from Ikea and it fits really excellent inside. This time I have chosen a soft mattress, but would still choose a harder again next time. But you can sleep well and comfortably on the mattress. During the day, the day bed used as a sofa. Again, the mattress is very comfortable. It also decreases when not sitting too far. I'll still order me with certainty 2, because you can also take off the daybed as a double bed, if guests stay, also is then during the day the seat height better. Strong buy recommendation
