We were looking for better lying and thus sleeping comfort of our bed. New mattresses? Even a new bed with box spring? Everything chewed. Actually, our mattresses were not bad, but can be really nice on you no longer. Just uncomfortable. Too hard. We wanted to really take a lot of money into their own hands, as we have encountered on these toppers and gave us after a long back and forth decided. Made in Germany has once again been a rash! It was the right decision. Delivery within 3 weeks - OK, I would have liked but also can imagine shorter! Bundled was the topper in plastic film. Placed on the mattress, covers over it and sample situated in the evening. The sleeping comfort has ceased immediately, but must be "learned". Why? Compared to our old and hard mattresses initially adjusts to a very soft, anschmiegendes feeling of the subsurface. I had, lying on his back, the feeling of wabbeln from left to right - almost like on an old waterbed. But then: In a comfortable lateral position (I side sleeper, my better half preferred side, back and stomach) and fell asleep immediately. Morning wakes up and nothing hurt. Neither the neck embarrassed, even the back, still feeling pressure in the hip bone - really very very convenient. When it comes on the weekend, I fall asleep by 10 hours. It was previously unthinkable! Meanwhile, the Topper has fully spread - he really grows a bit, maybe 3 to 4 centimeters. Sleep is good and comfortable, we apply the Topper regularly, the usual stuff, like mattresses also. We have 2 separate mattresses on top of 200 x 90 cm below and 200 x 180 cm topper, plus 2 cm thick, quilted pad thereon. We have no particular bed frames, to the always so much importance is attached. We have checked the toppers in cold weather and even in very hot weather (May and June 2014 gave yes both) and the result was really good. We never had the feeling that it's too cold or too warm was in bed. Our combination described above brings us since about 6 weeks every evening to smile when we go to bed. Good Night!
