Hi jeromylewis,
Post #2 here about making final choices when you are choosing between good and good may be helpful.
Just to clarify as well … the Brooklyn Bedding “Cool” series also has a free 120 day return policy.
Both also use high quality and premium foam layers so I certainly understand that it can be a difficult choice. In terms of quality and value you are in a great position where you really can’t make a “mistake” and you are in a much better position than the large majority of consumers that usually end up having to choose between “not so good and worse”
