The sheets are terrible.
The set is great for little train lovers, but the sheets feel like plastic. My 7-yr-old is not a complainer and he even said they are uncomfortable. I am going to buy a different sheet set to go with it. The comforter itself is very soft though and I was happy to find kids train bedding that was not that little blue #1 engine that starts with a "T". Great Offer Stock also had the cheapest price for this.
