Although it is stated the pockets will fit a mattress up to 21 inches, that is a bit optimistic ! My mattress barely is 16 tall and it was a struggle getting them on. Washed before using with cold water and dried on low heat. Already have pills on them. Hopefully with each laundering, that will resolve. 
Hoping they withstand regular laundering ! 

Color is nice moss/dark sage
Fit not as described.
