Pros: - Extremely supportive. After only 2 nights, my lower back ache went away completely. - Does a great job of preventing movement from transferring from one side to the other. Some movement still transfers, but it's much better than a traditional coil mattress. - After the break-in period, I find it to be very comfortable. For my wife, it's just good enough. - Doesn't seem to retain heat, though I have yet to sleep on it during the summer months. - Feels very solid and durable. But only time will tell... Cons: - It took a good long while to break in before finally feeling comfortable (~1.5 months). During that first week, my wife and I both hated it. Each night got gradually better after that. - Even after 2 months of nightly use, it's still not quite as soft as I'd like. I still notice pressure points towards the end of the night, and it's firmer than my wife would prefer.
