Does anyone have an opinion on base core for a DIY mattress between FBM LUX or HD36 HQ?

I am trying to decide between 5" base HD36 HQ or 3" HD36 HQ and 2" LUX.

Have requested twice for samples from FBY but haven't received any. I don't know the firmnest of the 2.

Side sleeper around 170lbs.

On top of base core, 3" latex 32 ILD and 2" solf latex.

Thanks

I am using the FBM LUX-R 5" in one of my setups.  It's very firm.  The LUX-HQ is denser, will last longer, is I think as firm as it gets.  Can't speak to your layering concepts because this is all new to me.  ("R" just means regular, "HQ' high quality).  LUX firmer than HD36.

I would think start with the firmest base, then layer up to a talalay topper.

p.s. if I'm wrong please any veterens feel free to correct me.  We all need to stay informed in order to make decent choices for our sleep!

If you don't mind spending the extra money the HQ is just better quality. Only downside I can see to HQ is its will be heavier to move around. 

I ordered samples form fbm and a week later I  had them. They are 2" x 2" samples and you can not tell much by them. 

I order the HD36 after reading how firm the Lux was. I weight 5'9" and weight 155 pounds. The HD36 is still pretty firm. i have 3 inches of latex foam on top. At my weight the Lux def would of been too firm.

After some time I have notice the HD36 is getting softer in spots, but has not lost support.  That why I recomend the HQ. I don't think the regular will last to long but this was only a temporary solution. 

Most of the awful smell is gone but I can still easily smell the foam. I do not mind it but if you have a sensitive sense of smell then it might offend you. 

I used 3" of LUX-HQ and then 3" of HD36-HQ on top of that.  With MF and latex toppers on top (zoned, see my other postings).
