As of June 2015, reviews of Serta Perfect Sleeper mattresses are online at Amazon.com and US-Mattress.com. On both sites, user reviews are accompanied by ratings based on a five-star system.
Amazon.com offers several types of Serta Perfect Sleeper mattresses. Five-star reviews mention good support, reasonable price and high comfort level. However, certain individuals report the Serta Perfect Sleeper is too soft and has coils that sleepers are able to feel.
Reviewers at US-Mattress.com state that back pain has disappeared since they started using Serta Perfect Sleepers. In addition, people are able to flip some of the mattresses, which extends their lives. Less enthusiastic reviews say that the mattress quickly develops depressions in the spots where people sleep.
