We purchased a Beautyrest Black Harmony Diamond Series medium 4 years ago and the foam has already failed. It was causing both of us serious lower back pain. We tried the warranty route and we’re denied since it hadn’t failed enough. We assumed that the springs in the mattress would still be good, so we pulled all of the foam out of the mattress including the foam below the springs. The springs appeared to be level and there were no visual issues with them so we started trying to build a DIY mattress on top of them. As many here know there is a ton of trial and error with a DIY build. We have been doing just that for many weeks now without much luck so I’m hoping to get some thoughts here on what may be our next best trial. Our challenge on all permutations so far has been that I seem to have a very small range where my lower back isn’t painful. Too hard or too soft and I wake up in pain and the slightest changes seem to put us on one side or the other. The 2 set ups that seem to be closest are
Too soft set up bottom to top:
Beautyrest springs
1" medium latex from SOL
1.5" memory foam (sinweek is the brand cheap stuff from Amazon we already had)
2" soft latex from SOL
Too Hard set up bottom to top
beautyrest springs
1" medium latex from SOL
2" soft latex from SOL
we also tried without the medium didn’t seem to make much of a difference both options were close but still too hard
I think we need some new options to try, would a 3” soft from SOL be what is needed – would that still be too hard? Should we look at buying a Talalay topper in either 2” or 3”. We need a way to add a little soft to the too hard option while not losing the support it provides. Do we need to just give up on the used springs could they be the issue? They seem fine but maybe I’m missing something?
