Simmons Beauty Sleep Baby/toddler Mattress

My sister bought this in 2015 but never had her baby sleep in the crib. When they moved in 2018 she gave to me to sell but I forgot until now. I believe she said it’s organic but I’m not possible if she was taking about the mattress or something else. You can look up the brand for yourself. Great quality. No pee stains or anything like that. Again wasn’t used. I have no use for it. The last picture is of a pottery barn sheet that you put so it covers the bottom of a crib. Idk what’s the proper name of that is. You can have if you want and I also have a Burt’s bees sheet for the crib which you can see in the pictures. It’s yours if ya want. I’d wash it. It was clean when I got but it’s been sitting in our extra room so I’m sure it’s dusty
