What really turned us on to the ReST Bed is it was the only bed that seemed to have it all. With its multi-zone air foundation, you get the most customizable comfort on the market. With its responsive tech you get the smartest bed on the market. Wrap all that in one bed and it is the best of all worlds combined. But theirs the extras like the zip-off machine washable cover. The modular design that gives you piece of mind that any if any part every fail or becomes less that perfect your can just replace that part. And finally the use your own credit card to finance so you can spread out the cost and get points while your credit does not get dinged for signing up for a new card you will only use once. This is truly one of the best purchases I have mad. Truly a bed for life.
