The good news is, you have a new mattress and not one that someone else returned using a comfort exchange....scary to think about, but something that happens quite a lot.
The time it will take to feel like the floor sample could be quite a bit longer. The floor samples are quite a bit older and many people have plopped on them.
Pillowtops wear out quickly and this is a long term purchase. You can always get a topper to soften the surface of what you have.
If you are heavier than average, the topper is an excellent idea for the longevity of the mattress, since you can't flip them anymore, they generally last half as long as they used to.
Latex is the best kind of topper, as it is the longest lasting. Shown here:
Whenever you are choosing a mattress, you have to figure on a new one feeling firmer than the floor sample.
