We purchased the ReST Original about two months ago, and our sleep quality has definitely improved. We used to wake with aches and pains almost every morning, and I was often out of bed by 5 or 6 am, because our tempurpedic just wasn’t comfortable anymore. Now I’m regularly sleeping until 6:30 or 7:00, and don’t wake up with pain. I’m taking off one star from my rating for the Night Vision app, which monitors your sleep quality. It was one of the reasons we chose the bed (so that we could “dial in” the best settings for us), but it’s still a work in progress. We have had issues receiving our “sleep scores” each day, and have had to reload the app several times. We’re waiting for the next update of the app, which will hopefully resolve those issues. But overall, a great bed.
