This is a baby bedding set. It's a regular size, and the mattress measures 120cm x 70cm. The set includes a mattress, quilt pad, comforter, mattress cover, comforter cover, and waterproof sheet – a total of six pieces. Originally, it was an eight-piece set, but the pillow and pillowcase are missing. I purchased it new in 2020. My baby didn't sleep in the crib much, so it hasn't been used extensively, but as you can see in the photos, there are some yellow stains in places. Otherwise, I don't think there are any tears or noticeable stains. It has been home-cleaned. Please refrain from purchasing if you are concerned about it being a used item. Thank you for looking.
