Hi techmattr,
The better options or possibilities I’m aware of in and around the Pittsburgh area (subject to the quality/value guidelines here) are listed in post #2 here.
While they may be “designed” in the US ,… they are made in China so there would be subject to the same uncertainty as any other mattress that was manufactured in China that I mentioned in the link in my last reply. Perfect Cloud also isn’t listed on the CertiPur list here. Dura Global is just an US based company that is an importer.
Outside of PPP (Posture and alignment, Pressure relief, and Personal preferences … a mattress is only as good as it’s construction and the type and quality of the materials inside it and I would never buy any mattress where you don’t know the type and quality of all the materials in the mattress (see this article).
While it’s not possible to quantify how long any mattress will last for any particular person, if a mattress is well inside a suitable comfort/support range and isn’t close to the edge of being too soft when it is new and meets the minimum quality specs that are suggested in the guidelines here then it would be reasonable to expect a useful lifetime in the range of 7 - 10 years and with higher quality and more durable materials that are well above the minimum guidelines like latex or higher density memory foam or polyfoam (in the comfort layers especially) it would likely be in the higher end of the range or sometimes even longer.
If a mattress doesn’t meet the minimum guidelines then in some cases it may only last you for a year or two before foam softening and breakdown takes you outside the comfort/support range that is suitable for you and you would need to buy a new mattress. I would also keep in mind that warranties don’t cover the loss of comfort and support and a 25 year warranty is only about marketing not about the useful life of the mattress (see post #174 here). Return shipping costs for a warranty replacement can also be more than the cost of the mattress itself as well which of course would mean that a warranty claim wouldn’t be worth it anyway.
An innerspring mattress with good quality materials and components (unlike most of the innerspring mattresses sold in the mainstream industry) can also be a very durable choice that can last you for well over 10 years as well.
I would never buy any mattress that used lower quality/density materials or where I didn’t know the type and quality of all the materials inside it so I could make sure there were no lower quality materials or weak links in the mattress (see the guidelines here).
I wouldn’t buy a memory foam mattress unless the memory foam and polyfoam was either made in the USA or was CertiPur certified.
I would be very cautious about buying any mattress where you aren’t confident that the mattress would be a good match for you in terms of PPP unless it also has a good exchange or return policy. There is also more information in post #2 here about the different ways to choose a mattress (either locally or online) that is the best “match” for you in terms of PPP (Posture and alignment, Pressure relief, and Personal preferences) that can help you assess and minimize the risks of making a choice that doesn’t turn out as well as you hoped for that are involved in each of them.
I would also be very cautious about using other people’s experiences or reviews on a mattress (either positive or negative) as a reliable source of information or guidance about how you will feel on the same mattress or how suitable or how durable a mattress may be for you and in many cases they can be more misleading than helpful because a mattress that would be a perfect choice for one person may be completely unsuitable for someone else to sleep on (see post #13 here).
If you are limited to lower budget ranges then some of the better lower budget online options I’m aware of are also listed in post #4 here.
There is also more about the most important parts of the “value” of a mattress purchase in post #13 here that can help you make more meaningful comparisons between mattresses in terms of suitability (PPP), durability, and “value”.
Needless to say … this certainly wouldn’t be an option I would consider and it wouldn’t even be close to the top of my list compared to the many other good quality/value options that are available to you that wouldn’t have the same risks.
