The way we rank and rate is the following. In order to determine the ratings we use the mattress price, the company's return policy, brand popularity, warranty, live promotions, mattress quality and more.
In addition to all these factors advertising fees that help us keep the website fees are combined to the formula and effect the final score. They are not the main factor we take into account when scoring.
The website doesn't cover all brands out there nor do we claim our rankings to be the whole truth. Ranking and rating is complicated and there's always a personal prefrence we can't take into account
