I bought this to replace my Simmons beauty sleep king mattress, which after 2 years was already showing signs of sinking in some places.This mattress is pretty comfortable. I was surprised by the value myself. We'll see how it holds up over time. So far so good! Super comfortable if you're a back sleeper.Setting up can be tough. Get someone with some strength to hoist this thing up stairs. Layout on top of your box springs before cutting this thing loose from the vacuum sealed plastic. After that, it expands into place very easily. It does have a new foam smell, but that faded after 2 days.
