It is nice and firm. I like the feel of this mattress and sleeps well. However, what I did not anticipate was how noisy it might be. Perhaps its because I've used a foam mattress for so long, but still I've slept on other innerspring mattresses and have never noticed it squeak before. To be fair, it doesn't squeak when turning over at night, thank goodness, but only when sitting down on it or lightly bouncing on it. It is kind of annoying and not what I expected. I've only had it a few days, but I'm likely going to return it and try to find a mattress that is both firm, comfortable and quiet.
