Hi thanhhiep.
Welcome to our Mattress Forum!
I just noticed your earlier posts with the two photo attachments in a different topic. I apologize! these were somehow lost because of the discussions in progress with other contributor members. I moved them to this thread and deleted any duplications.
You are quite right that outside of PPP (Posture and alignment, Pressure relief, and Personal preferences) ⦠the most important part of a mattress purchase is the quality and durability of the materials inside it but unfortunately the pictures you attached donāt provide all the information about the quality of the materials in the mattress so itās really not possible to make any meaningful comments about it, identify any weak links in the design, or make meaningful comparisons with other mattresses.
You can see my overall thoughts about Paramount in post #9 here but I would also read posts #5 and #6 here which indicates that they are not transparent about some of the materials they use in their mattresses (in this case the density and thickness of the foams).
The gel that is added to some types of latex or memory foam is a phase change gel that can absorb and release heat within a certain temperature range to help regulate temperature. So-called āsoy-based foamā is just polyfoam that has replaced a small percentage of one of the two main chemicals used to make the polyfoam (the polyol) with a polyol that is derived from soy oil (see post #2 here ). It would be closely comparable in terms of durability to other types of polyfoam that are the same density range. I would want to know the density of any polyfoam in a mattress.
All the latex you are likely to encounter is a good and durable material. The addition of copper used as a filler (such as TGs āTalalay mineralā) is generally used to improve the processability and heat transfer (due to the increased surface area) of the PCM. The benefits of Cu used as a filler in both memory foam and latex are more connected with its thermo-conductive properties and even though copper infused latex is advertised as having side āhealth benefitsā (such as copper bracelets) to my knowledge these benefits have not been proven in copper infused foams. The main benefit for adding Cu to latex or memory foams would be for thermal conductivity (which generally is not an issue with latex, to begin with) so I personally would not make a priority to choose one over the other (with or without copper). Other than this if you can provide the information listed here Iād certainly be happy to make some comments about the quality of the materials in the mattress and let you know if I can see any obvious weak links in the design.
I would ask Macyās to find out the information for you because they may have better results than you since other forum members havenāt been successful in finding out the information they needed directly from Paramount (see post #2 here and the posts it links to about Paramount) and if you arenāt able to find out the information you need to make an informed choice I would be hesitant to make the purchase no matter how appealing the sales price might be.
Sales are more about the illusion of saving money than they are about reality ⦠While itās not possible to make a blanket statement about sales because each retailer or manufacturer can be different, I would treat retailers or manufacturers that negotiate their prices or have āmajor holiday salesā with huge discounts as a red flag as a most of the sales are more about creating a false sense of urgency. The better manufacturers and retailers that sell good quality/value mattresses donāt generally ānegotiateā and they sell good quality/value mattresses every day of the year at prices that are already very reasonable. (see post #6 here ) or have āfake salesā based on the time of year or holidays (see the guidelines here and post #5 here ). In other words ⦠if you are dealing with a better retailer or manufacturer that sells better quality/value mattresses then one time of the year isnāt really any better than another.
Just in case you havenāt read it already ⦠post #1 here and the tutorial post here that have all the basic information, steps, and guidelines that can help you make the best possible choices.
Hopefully, this gives you enough information to help with your research.
I would be interested to hear back from you to learn what you decided and I or any other Expert Member of the site would be glad assist you with any questions that you may have.
