I have been shopping for a mattress pad for months that has sides that are not paper thin. Actually returned a few because the sides were so cheaply made. I was delighted to find this one since the photo shows sides that are solid, not pleated with what looks like tissue paper. 
Sadly, the pad I received looks nothing like the photo shown. Very disappointed and feel like it's false advertising.  You can compare the 2 products and clearly see they aren't the same on the sides. The top is great, but sides are so paper thin that you can put your fingers through easily.
