I tend to like rather firm beds, usually placing an egg crate on top if they aren't the best quality or old. This mattress has enough give that it's not like sleeping on a rock, but it's supportive enough that those of us with less-than-perfect backs can rest comfortably and not wake up with pain. The coolest thing about this mattress is the way it's delivered. It arrived in a box that you would never believe carried a mattress and when you open it up and cut through the vaccuum packing, it expands to full size within a minute - ready to sleep on! I've had it about 3 weeks and I have really enjoyed it. Since it's a Serta, I anticipate it continuing to make a great bed for years to come. I would definitely recommend it to others.
