I was surprised just how easy it was to put these on.  Have only had a few weeks and they seem to work really well.  Having had an issue with bed bugs before in a room mate situation we were really wanting to protect the mattress.  We have a 14.5 inch mattress and this cover fits perfectly.  The only thing I wish was that the king size came in 2 options - one for a solid box springs and one for split box springs.  Putting the mattress cove on was a piece of cake.  The box springs because of it being a split box spring was a little harder.
