    My husband and I bought this bed about a year ago from the Delta Park location and we love it! Every other year we’ve had to get a new bed because they break down too fast. This one still feels the same as the day we got it. Would definitely recommend to anyone who has had the same issue we did.

    Best mattress fit for us hands down, firm enough to support my back when sleeping and the pillowtop helps if I roll over to my shoulder while asleep, very happy!
