The mattress has arrived with a oil mark on , this is for my baby grandaughters first “ big girl “ bed , it looks like the mattress was run , over the driver had brought it in and positioned it  against a wall , not with the oil mark showing , only when we went to take it upstairs , to put on the bed , did we see it, I am unhappy I have had to put on the bed as we have got rid of her cot .
