This is the most high quality mattress (and boxspring) I have ever slept on. It's even better than more expensive mattresses I have owned. You can tell that every single part is high quality. I've slept on it about six months now and it is as new as day 1. It is very, very heavy and I can barely rotate the mattress on my own. Even the guys who delivered this were curious and impressed by it's build. I anticipate that this mattress will last a minimum of 10 years and quite possibly 20. I found it to be very firm and purchased a high quality 2.5 inch thick, 4.5 lb density memory foam mattress topper for it to make it super cushy. I did this because the cushy part of mattresses always wear out and I wanted it to be replaceable. The top of this mattress is fine, I am not saying it will wear out, but I need super duper softness. I also need a great and supportive mattress for the cushiness. So I searched and searched for the most high quality mattress I could find and took a chance on Big Fig. Glad I did. Now all my friends and family want one. They literally say, "This is the most amazing bed I've ever felt." And they are right!
