I bought this for my parents to replace their 25 year old mattress and needless to say it was a huge upgrade. My dad thought it was just a mattress topper because it came in a box but it is indeed a complete, queen size mattress. It was packaged well and securely but once it is opened there is no getting it back in the box. That’s okay though because this is a great mattress that you won’t want to send back. I tried it out myself and it is very comfortable. It’s firm but not too firm and soft but not too soft. The only complaint I have with it and it is minor is that it is a few inches wider than their old queen mattress. I don’t know if they’ve all gotten bigger since their old one was purchased or what was up with that but it hangs over a few inches on both sides. Again, not a big deal. This is a great mattress at a great value and I expect my parents will get many years of good rest from it.
