Prompt delivery of mattress and box foundation (separately). Assembling the foundation was easy, and setting up the mattress on it was straightforward. We let it finish opening up for 7 hours then slept on it the next night. From the beginning it has felt amazing: the right blend of soft comfort and underlying support. We can easily adjust our positions without feeling stuck, and no matter what position we rest in, the mattress instantly adjusts to keep us comfortable. Beyond that, avoiding the hassle of an in-store experience and paying such a great price has made the whole experience even better.
I actually LOVE this mattress. As someone who has used many (back and forth between divorced parent's houses & a lot of moving) I can say that this is by far my favorite. I will never have a mattress with springs again. Like ever.
