I've owned the medium firm hybrid mattress for 3 years now. I loved the feel initially. But after a year, it softened and developed dips in it. It feels more like a plush mattress than a medium firm. I have back issues so that's not great for me. I usually have a bit of back pain after sleeping on this mattress. If you love soft mattresses that "hug" you as you sleep, this may be for you, but if you are looking for a true medium firm/firm that lasts for years, best keep looking. I am sure you can find something better at a comparable price.
