We love these mattresses. They are firm yet soft. Durable with a family of two children, two dogs and two cats. They are fun to jump on as well as sleep on.
Have had new mattress for about two weeks and find it to be all and more than I expected. It was easy to open and very comfortable. Because I have multiple sleep issues it is difficult to say "best ever". After I have acclimated to the mattress I may well upgrade my evaluation.
