The topper does not fit the bed. I have a King and ordered a King. There are gaps at top and bottom and I constantly have to pull it up, shift it , move it back in place, etc. Very annoying. Also, it was supposed to be on the firm side  it is less firm than the last one I had that was on the soft side per their scale. I really wish I could exchangereturn. I have purchased mattress toppers from this brand in the past and was quite pleased. Not so much with this one
