Hi, R_And_F_Hater37,
Welcome to TMU.
Sorry to hear you have had issues with your mattress. The bedroom is not place to cause back pain, it is a place for pleasure and a good night’s sleep.
I have read on other sites that discuss mattresses that the harmony has had issues with sagging. I suppose if someone has complained about it, most likely it is true. It is sad to say that a variety of BR users have run into sagging issues in less time than one would prefer. I suspect that in the “big boys” category, it seems to be a common theme. It is not clear that the mattresses are just no made well or more people tend to complain when they run into an issue and just want to get it off their chest. I have my opinion about this phenomenon, but I will reserve that for another time. It is hard to compare this mattress to others as they dont offer a lot of information about it.
I suppose the harmony lux on the BR web site is the closest to this model. I mention this a lot, but when it comes to super firm mattresses, which is what I sleep on, I like it simple. Heavier gauge quality hardened coils 12.75 to 13.75gauge. If hybrid, a durable HD 1.8lb or better base foam under the coils usually about a half to an inch thick, with a HD foam above the coils for extra support and firmness at least 36 ILD and a firm quilted cover/panel. I find when manufacturers start to pile a lot of foam, particularly viscoelastic memory foam as part of the comfort layer and/or cheaper less durable foams, you tend to get the potential titanic, particularly in the bottom area. Many of the traditional brands that we have known for years do an ok job, but it seems to be a race to make the display model look like a luxury couch which is certainly eye candy to those who get that first visual and say wow. Until the candy turns out to be a sour patch kid.
I guess when you are making thousands or tens of thousands mattresses, a few bucks extra for each mattress in quality materials cut into profits enough that some of these manufacturers just figure, everything else in the world is becoming disposable, why not our mattresses. Planned obsolesce leaves the consumer with an expensive bill every few years rather than every 10 or 15. Private manufacturers like those featured her at TMU (https://mattressunderground.com/the-underground/our-trusted-members) along with a few online BinB’s are still doing it right and producing quality mattresses of years past. Like I mentioned, good support layer, simple quality comfort layer, durable cover/panel layer and you have a quality mattress you can count on.
That is not to say that at Hastens 17" mattress is bad as they use only quality materials. It just means if you are going to all Bouffant or pompadour on the mattress, it better be with quality materials otherwise that souffle will sink like it has cooled for hours. If you dont mind, what is your height and weight and if there is your significant other’s. Do you prefer a hybrid, all foam, traditional innerspring, or just a good solid quality mattress. While we wait to get your PPP’s ((Posture and alignment, Pressure relief, and Personal preferences) take a look at the shopping guide tutorial (https://mattressunderground.com/c-articles/687-mattress-tutorial-condensed).
Also, as you do your search, be mindful of the establishment you are looking at. Know what their refund, return, restocking fee and exchange policies are in advance to save you a potential headache down the road, just in case things dont work out as planned.
