I think you get used to it, the foam on mine feels as firm as it did five months ago. I don’t like lumbar support, so I have it turned right down on the Titan.the first week i thought it was too firm, but i'm not sure if i just got used to it or it broke in just right. i love it now. it's the best computer chair i've ever owned by far. i love the soft touch material also. i'm happy i went with that over the leather.
i did buy the lumbar pillow from the Omega chair to use with my Titan though. the built in adjustable lumbar was a bit higher on the back than i prefer. the Omega lumbar pillow has been a great addition.
