Hi lulylu,
I would run (not walk) away from any place that offers a 50% discount on a mattress or that tells you the sale ends at a certain time. These are just sales techniques designed to give you a false sense of urgency about buying a mattress because they know that if you walk out of the store without the sense of urgency that making reasonable comparisons will lead to you not going back again.
The Stearns and Foster latex are not “natural” Dunlop but a continuous pour blended Dunlop latex which is the cheapest form of latex. This doesn’t mean that it’s “bad” … only that it isn’t the same quality as better types of latex. While they do have one mattress that they say is all latex … a look at the law tag will confirm if this is true. Even if it is all latex these are not the highest quality materials and almost all of these have polyfoam included in the mix. A layering like this would be typical of S & F which has several inches of polyfoam and synthetic fiber over the core. Always look at the law tag if someone who is selling a major brand mattress claims they are selling an all latex mattress. There is more about Ortho, Stearns and Foster, and smart latex in post #5 and 6 in the San Diego thread.
Good manufacturers and outlets sell mattresses with good quality and value every day of the year and don’t rely on fake sales (and other techniques) to create a false sense of urgency to do their selling for them. Impatience and frustration is the best friend of these types of outlets because it mostly leads to poor decisions. A mattress is one of the most important purchases we make and will affect the quality of life for more than a decade and it’s never a good idea to make decisions like this without knowing exactly what you are buying.
You can do much better IMO … at some of the other outlets in the San Diego thread.
