I like the mattress topper but the slip cover that is over it came with the zipper tag off and I can not get it to unzip.
Not sure if zipper is broken or just can't get the correct grip to open it.
I will be contacting Wayfair with problem.

Also the dimensions are deceiving as the total depth is only 3.5" instead of 4" and it's 38.5" X  74.5"

I didn't not experience any unpleasant odor as some people have.
