Review on 🛏️ 100% Cotton Baby Crib Mattress Sheet for Boys and Girls - Comfy Cubs Fitted Crib Sheet - Pack of 2 - Fully Elasticized Hem for Snug Fit Over Standard Crib and Toddler Mattresses by Katie Parker

They will NOT fit a standard size crib mattress. I tore it trying to put it on the mattress. I purchased a pack of these pink crib sheets to fit a standard Delta mattress, size 5" x 27.5" x 52". The product description for these sheets states that they are for mattresses up to 6" x 28" x 4". 52" fit. NO. The pictures show how small the leaves are, they are too short. In other words, the side that should be 52 inches long isn't actually 52 inches long. I know sheets are supposed to be very thick, but they just don't fit. My partner pulled a sheet over the mattress and folded the mattress into a "U" shape. When I tried to put another sheet on top of the mattress (thought maybe one sheet was defective and the other was fine), the elastic broke in one corner. So now I think one of these will technically fit the mattress, but it's torn and unsafe. I can't return them because I foolishly threw away the original packaging. Don't make the same mistake I did! To run! Run to another set of sheets!
