We've been sleeping on it for about 2 weeks and are loving it. We slept on a very firm futon for 34 years and so were concerned about a mattress top being too soft for us. I didn't want something that cuddled me; I just wanted firm. This mattress fits the bill. My only concern is that since we don't use it with a box spring, it's a little awkward to make it with clean sheets since it's necessary to lift up the mattress to tuck it in. This could be a larger concern as we age, but then we can just get a box spring and a regular bed frame. For now we are sleeping very comfortably.
