We learned about Rest over a year ago, reading about them in the Wall Street Journal. I suffer from a severe back injury and have had difficulty sleeping for the past 14 years. It was time for a new bed and we drove over an hour to Luxury Matress, to check out the Rest performance mattress. We have had a temperpedic bed before, but it was to soft and too hot. We have had the Rest bed for about 4 months and have never slept better. My wife and I couldn’t be happier. We have the king split with very nice adjustables. I am sleeping through the night, I don’t wake up as sore anymore. We have had 2 sensors that needed to be replaced, but Rest over nighted new ones. Amazing customer service!!! We highly recommend Rest Performance!!
