Having worked for one of the major mattress firms, there are truths in the article, but also some serious mistakes.<p>The pricing structure, where they hide the models by using different names across retailers, is 100% true. They absolutely do that to prevent price shopping.<p>The markup math is off. Mattresses are a high margin business, but most of those mattresses you see in specialty retailers are not built until someone buys one. You see, those mattresses are custom to the customer - from the tick (stitching pattern, which creates a firmer or softer surface) to the foam density, to EVERYTHING. It's like ordering a car where the car is measured to a specific person's height, weight and engine preference. You can imagine what a returned mattress is worth. Pretty much nothing. The margins have to cover all of that. Are the margins good? Yes. Would a small company be able to cut their margins to make one-off custom mattresses and compete? ...maybe.<p>Finally, there are retail outlets - Costco, Ikea, that buy from those mattress companies in bulk and sell generic mattresses much cheaper.<p>So, yeah, there's some market there but not as rich as some might think.
