Our Helix mattress is everything that it claims to be! That is a bold statement in today’s world of influencers steering our buying decisions. It was delivered when expected, the instructions are clear - YouTube video tutorial as well as paper. It installed easily and it was fascinating to watch it unfold. We have not given any thought to the trial period. We have had amazing sleep from the first night. The pillows that came with it have been equally comfortable. I am so thankful that we made the decision to get a Helix mattress. It is the most comfortable mattress we have ever had.
