This is already the 2nd mattress Soft wave H1 we bought from Ravensberger M.. So far, there is simply nothing to complain about. The first is now already 2 years old, the last we ordered two days ago and she is already in bed. The mattresses are intended for our children, both at 45 kg light, but also we adults sleep visit as simply superb on it. You feel like on a soft shaft; o) and is in the morning really relaxed and rested. From our children and no complaints about the sun came behavior. And what for me (in charge of the laundry) is the icing: If time passes a Maleur, you can either divide the mattress cover and plug only the upper part in the WaMa - awesome. The bulky mattress (we have 120 and 140 he) remains just lie (the lower part of the cover, of course, remains as where it is) and after drying I zippe the top just back on it. Thanks for that! Oh yes, a topper can save for the thick cotton cover also, which is very soft padded (not sweaty) - and no, I'm not getting paid for the advertising, I'm going to have just glad found good and affordable mattresses in I have no restrictions.
