We have built the bed guard after we have let it air out for a few days. Plastic has always the property something auszudünsten. For this price and that the product was manufactured in China, we are very positively surprised about it. It can be a bit difficult to assemble, but the fabric is really taut and the product looks good. Also, it is easy to sink under the mattress and keeps super. We had another grid of a renowned manufacturer and this part has kept not so good. Therefore, thumbs up for this product at this Prei.
