Very disappointed with this mattress bad.  I was looking for one that made the bed more comfortable and cooler to sleep on.  Can't tell a difference on the comfort and it's hot to sleep on.  It arrived with several snags on the top.  The sides don't look like they'll last.  I would have been just as well off and maybe better with one of their cheap mattress pads.  I tried to get it back in the box to return it but that wouldn't happen.  So I'm keeping it rather I want it or not.  I don't recommend it.
