Hi Christine,
As you can see in post #9 here … I think highly of Relief Mart and Dr Rick, they use good quality materials in their mattresses, and none of them have any weak links in their design.
I’m not as big a fan of airbeds however (see this article) but having said that … theirs has a separate firmness adjustment in the center zone which can help offset some of the inherent weaknesses of most airbeds and the urethane air bladders themselves are more flexible and durable than most types of air bladders (which can add some progressive resistance to the air) and the comfort layers they use above the air bladders are all good quality materials so they would be a “better” choice in terms of quality, durability, and performance than most of the competing airbeds on the market IMO.
