Good Day mymypunhrrp,
It is great that you have done some research in your neck of the world. Yes, there are some gimmicky mattresses out there. Like all things, there is good and bad. Therapedic makes some nice quality mattresses. I am not quite sure that they would “dummy” down their mattresses for the international market. Unfortunately, without directly contacting the company for the specs on the mattresses being offered in your area, it is hard to know.
Not all countries require that law label on the mattress and have the strict standards that we have here in the USA.
I know that trusted member #mattress to go has a full line of Therapedic mattresses in their lineup.
Some offer foam encased perimeter coils and some offer edge to edge coil construction. I would guess with Jeff’s direct experience with the company and extensive experience in the industry, he might have better insight to what might get shipped overseas or manufactured in the overseas market by TheraPedic.
Remember, knowing the construction and quality of the materials is simply one step in finding the perfect mattress. Matching your PPP (Posture and alignment, Pressure relief, and Personal preferences), along with your body profile, weight, height, any other physical issues or requirements play a major role in the ultimate matching of mattress to user.
It is perfectly understandable if you have limited resources to actually try the mattress in a showroom, then you may have no other choice to rely on specs of the mattress and generalized information about the mattress to best guesstimate what will work for you. Quality materials naturally is the 1st key ingredient (jokingly, you can end up with a great quality mattress that may not be all that comfortable for you). Fortunately, if you make an error to the firmer side, a mattress topper may help resolve the problem.
Perhaps, you could start by providing some information about yourself, what your preferences are, body profile, and then if we can find out more about the Indian Market mattresses produced by TheraPedic, we can come close to nailing down the most likely candidate for your perfect mattress.
Knowing that the “Tango” was too firm is a good start, now we just have to find out what is inside of it. In some cases, the order in which the comfort layers are laid out, densities of their foams, etc. may indicate that a mattress like the “Tango” may actually be Perfect in the long run, as some layers used in the comfort layer of a mattress soften during the first month/s of use, landing you right where you may want to be.
I would agree that thin layers of foam may not be a recommended thing. This is not always true. If you have a 1/2" of HD PU foam that is 1.8lb or so, it can be used as a transition layer or a base layer in the mattress and would be perfectly acceptable.
In so far as an all-cotton mattress, on a good foundation, personally, I see no issues with it. But remember, mattress layers are designed to carry out different things and are directed to target specific parts of the body. For example, Trusted Member The Clean Bedroom sells a couple of lines of mattresses that are comprised of mostly all cotton. Some with the added support of pocketed springs for specific body alignment and contouring, some with layer/s of other natural fibers to complete the perfectly constructed mattress. A simple solid cotton mattress is really not uncommon though. In the State where I live, these folks offer cotton, cotton and wool, horsehair combinations, Cotton Mattress. It is just not what most people portray as mainstream, so it is not talked about as much.
Hopefully, this is a good start for you. Looking forward to getting some updated other information.
All the best,
Norm
