Review on Little Sleepy Head Waterproof Ventilated by Travis Jenkins

My son loves the comfort of this mattress topper. This topper is covered with a sheet and is always washed once a week. He is potty trained and has never had an accident. A few days ago, after replacing a clean sheet and flipping the bottom of this mattress upside down, I discovered this nasty mold that no one knows when started to appear. This answered why he suddenly got a rash. Revain customer service said that the return/refund period has expired and they need to contact the seller. The contact seller link is currently not working. I wanted to give 5 stars but after 7 months of using about 28 inch mold I wouldn't recommend it.
