We’ve had our Rest Performance Bed for 2 months and we love it more every day. We got the Top-split king bed. Now we can each manage the firmness the way we like it. It did take about a week or so to figure out which settings we liked best. Me -I set each section and leave it. My husband uses the auto setting that adjusts based on sleeping position side or back. We also bought adjustable base that Rest team recommended off amazon! Its all great! We were considering a Sleep Number but decided after much research and blog reading to go with Rest and we are glad we did.
