When my daughter and her husband recently were planning a trip to visit, I realized my son-in-law, bless his heart, would hang off both ends of my queen mattress.  So I set out to obtain a comfortable king-sized mattress for my king-sized guest.  I was a little apprehensive because I didn't know much about the Novilla brand, but I saw it was getting good reviews.  I thought I would try it and, if it wasn't comfortable, I could just return it.  Wow, was I happily surprised.  My daughter and her husband both raved about how well they slept and how comfortable this mattress was.  Great vacation . . . happy guests, happy mother-in-law.  Thank you, Novilla, for making a comfortable mattress at an affordable price!
