Have the Matzratze bought for our playpen in which our daughter from day one keeps their Tagschläfchen (or should). However, she was very restless and quängelig from the very beginning, when we put them in. Fortunately, we quickly came to the idea that you might alone despite softer pad is too hard the part and then ordered Matzratze on the Amazon Warehouse Deals the Träumeland. A little cheaper than regularly and in Amazon Speed with us. The Matzratze fits exactly and therefore not annoying wobble back and forth. The design of the cover (washable), we find quite ok. The hardness and thickness of our daughter seem ideal because it is sleeping like a little angel. Great Thing!
