I have purchased three matresses for many members of my family. The first matress was purchased over 2 years ago and it is holding up well under the duress of a teen. The last two matresses were for my aging parents - one experiences back pain with normal matresses. They are very satisfied and love their new matresses. These matresses are a good deal and sleep great. Please note the "unpacking" directions since the matress comes compressed. A compressed matress may seem a little wierd but I have had no issues however I did follow the unpacking directions very closely.
