Slip-resistant, cold-insulating floor, comfortable, nice color - So what's to complain about? My nose was when I unpacked the mat, smells strongly of whatever (not the typical plastic odor, sweetish unpleasant and quite strong). I have therefore once relegated to airing in the basement. Unfortunately, the smell, immediately triggered the chain of thought in connection with the great softness: I want to lie down on a mat, which is possibly heavily contaminated with plasticizers, which I take probably over my skin? Finally, you sweat when Sporteln neat and lies partly with the bare skin on the mat. You can about the effects the substances mentioned above easily inform the Internet. Here is neither the product nor the packaging side of the product information on the material. High quality foam - what does that mean? Because of the insufficient material specifications and therefore the odor from me only two stars.
I highly recommend this mat only recommend those that above objections can not understand and they consider exaggerated.
Especially in children (the color's for little princesses as created) but I would necessarily rely on natural materials.
