Detailed review protocol
How we Evaluate Product Value
How we combine product performance, current pricing, comparable alternatives, and tracked price history to assess value without relying on advertised discounts.
Value begins with performance
A low price is not good value if the product does not fit the user or fails at the job it was bought to do. The mattress rating covers performance, durability, and Buying Protection. Deal Truth then places the current price beside that result without changing the rating.
Deal Truth price tracking
For mattresses, we record dated final prices for the same size and configuration. Each checkpoint can include MSRP, coupon requirements, gifts, availability, and source. We publish good, typical, and high tracked-price context only after at least three comparable checkpoints are available.
The ranges are generated from the stored price history. A large advertised percentage, countdown timer, or repeated holiday label does not determine the verdict.
How value appears in reviews
Mattress reviews include Buying Protection as 4% of the overall rating. Current price, advertised discount, and Deal Truth do not enter the score, so a promotion cannot disguise weak performance or rewrite the mattress's product rating.
For pillows, bedding, blankets, and sleep technology, value is assessed through hands-on use, category-specific performance, durability indicators, policies, and the price of credible alternatives. These categories use their own ten-point rubrics, with category-specific metrics published alongside the review.
