Membership is not offered or accepted lightly and it indicates our recognition that they have the knowledge and experience to help their customers make informed buying decisions and are among the best choices in the industry. Read more about the TMU Trusted Members approval process

All TMU Members have agreed to provide a bonus/discount to the consumer subscribers of this site (those who have made at least one post in our forum). Simply mention “The Mattress Underground” when you visit their store or use the discount code provided below when purchasing online.
