Hi cristyhawaii,
I would look for a mattress with the best “value” rather than looking for the “best deal”. While the price of a mattress is certainly one of the more important parts of the “value” of a mattress purchase … there are many other parts to the “value” of a mattress purchase as well and unfortunately there isn’t a “formula” that can be used to assess or “calculate” value because there are so many different variables and criteria involved that may be more or less important to different people. In other words … the “value” of a mattress purchase is always relative to how it compares to the other finalists you are considering or to the other mattresses that are available to you in your area or online (if you are also looking at online options) in terms of PPP, the quality and durability of the materials, and all the other parts of your personal value equation that are most important to you. There are many reasons that a mattress that may be “good value” for one person may not be worth considering for someone else.
There is more about the different types and blends of latex in post #6 here. In some cases blended latex can be more durable than 100% natural latex yes but in general terms latex is the most durable foam material regardless of the type or blend.
This would be strictly a preference and budget choice rather than a better/worse choice and both types of latex can make a good choice in any layer of a mattress. There is more about how Dunlop compares to Talalay in post #7 here but the best way to know which type of latex you tend to prefer will be based on your own testing or personal experience.
There is more about Tuft & Needle and many of the other “simplified choice” mattresses in post #2 here in the simplified choice topic and there is more about the foam they are using in posts #2 and #6 here. The comfort layers are a high performance polyfoam and their support core is conventional polyfoam and both of these are synthetic materials.
That would depend entirely on how you are defining “better”. Assuming that the materials in a mattress you are considering are durable enough for your body type and meet the quality/durability guidelines here … the choice between different types and combinations of materials and components or different types of mattresses are more of a preference and a budget choice than a “better/worse” choice (see this article).
Having said that … The materials in the BestMattressEver (latex comfort layers and a 2.0 lb polyfoam base layer) would be more durable, and more costly than the materials in the Tuft & Needle mattress (high performance polyfoam and a 1.8 lb polyfoam base layer) but only you can decide which one is the best “value” based on all the criteria that are important to you.
Both Brooklyn Bedding and Dreamfoam are members of this site which means that I think very highly of both of them and I believe that they compete well with the best in the industry in terms of their quality, value, service, knowledge, and transparency. (NOTE ADDED: Tuft & Needle is no longer a member of this site … see this topic)
Dreamfoam’s Ultimate Dreams line of mattresses include memory foam, latex, latex hybrid, and polyfoam mattresses but in general terms they are great quality/value choices that use good quality materials. How any specific Ultimate Dreams mattress compares to another mattress would depend on the specifics of the Ultimate Dreams mattress you are considering and on the specifics of .the mattress you are comparing it to.
