Great Buy
This mattress was purchased for my daughter’s twin over full bunk bed. She loves it. It’s not firm, yet not to soft.

Great (Pain Free) Night's Sleep
Some time ago, I tore my right shoulder rotator cuff and have been in almost constant pain ever since - the first morning after sleeping on our new mattress, I awoke with almost no pain in my shoulder and each morning thereafter.
Now into our 3rd week, we love our new King Classic Mercer Hybrid mattress.
