Hi Brett,
While they certainly aren’t the only ones that provide inaccurate, misleading, or even deceptive information on their website … I completely agree with your comments.
Polyfoam of various types such as the 1.8 lb polyfoam that they use as the base layer in their mattress is one of the most common and least costly materials in the industry and the high performance polyfoam that they use in their comfort layer is also one of many similar versions that are used in many mattresses (see posts #2 and #6 here) … including many other “simplified choice” mattresses that they compete with.
Basically their mattresses contain two different versions of polyurethane foam.
As you also mentioned … their foam provides increasing resistance and becomes firmer as you sink into it more deeply which is no different from any other foam material or even innersprings although the compression curve of different types of foam or innersprings can vary widely.
I should also add that their comments about “markups” are also very misleading and deceptive (see this topic) and “normal” markups or margins are nowhere near what they are claiming they are.
As an example … the Dreamfoam Arctic Dreams here uses a 6.25" 1.8 lb polyfoam base layer and a 3" 3 lb density Energex comfort layer (which is a similar high performance polyfoam) and a 3/4" polyfoam quilting layer and is a very similar design and currently sells for $299 (queen size) vs the $600 of the Tuft & Needle (queen size) although it’s made by a factory direct manufacturer with their own factory rather than a reseller such as Tuft & Needle which doesn’t have their own factory and is made by someone else.
Sadly … I would have to agree with this as well. While they have always had some misinformation on their site … like many other companies as they have grown larger they seem to have lost their way to some degree and become less “mattress people” and more of a “marketing machine” and their marketing has become more of an example of “the end justifying the means”.
