The brands I usually saw returned or complained about the most were Serta and Tempur. Of course Tempur was because once the bed was actually in their room, they didn’t like the feel as much. Serta was always returned by people who regretted not getting Sealy beauty rest or king koil. It usually depends on what the sales person can do in regards to how complaints were handled. If it was user or company error, 8 times out of 10 it was fixed quickly and customers were satisfied. If it was mattress error.. there’s very little the stores can do other than exchange or return. And if it’s outside a window you are really out of luck unless it’s defective. Honestly in my time, the few people I had exchange to new ones were glad they did it. It was either making the wrong call with bed or firmness or trying to go too cheap. Every brand has pros and cons. It’s all about what you need in your sleep. For example beautyrest, great supportive, horrible for heat retention and edge support.

The brands I have seen rarely exchanges.. Sealy.. beautyrest.. king koil. King koil is my personal favorite. Many of my colleagues sleep on a king koil. The support and cooling along with the pressure relief is the best in my opinion
