We have two of these mattresses for our children, today one of our children had an accident on the bed which prompted us to take off the mattress protector and sheets. Under all that is another mattress cover that came with the mattress. We also had to remove that. It was very hard to get it off and now we realize why. There is fiberglass covering all over the mattress. we had to throw the entire mattress out all of the sheets that we washed the covering with and buy a whole new mattress from a local store. It is absolutely insane to us why anyone would use fiberglass in something that people are meant to sleep on. do not buy this mattress. We are looking into taking legal action against the company. This could’ve caused major health issues. Luckily we caught it and didn’t just put all of the bedding back on. We are now out over $500 worth of bedding and mattresses. Not to mention the amount of fiberglass that is now in my hands from being on aware that the mattress was covered in fiberglass until it was too late.
