Mattress Forum

We initially added a 1.5" geo cut "Memory Foam Bed Topper by Beautyrest" that I bought at Bed, Bath & Beyond.  It was too soft of a topper anyway, and did nothing to lessen our discomfort.

I then found this forum, and based on something I'd read here, I ordered the 1.5" Bryland Home 1.5" topper.  I have no idea what ILD it might be, as Brylane doesn't address that.  We placed it on top of the memory foam topper.  That helped a lot, but my husband and I still wake up stiff and achy.  I think we are bottoming out on the too-firm mattress below.  We are both heavy (Hubby is 235 and I am 185). 

This past weekend, I slept at my brother's house on his Denver Mattress ASPEN, which I understand to be a Talalay latex.  No pain, no sleepiness, and I could bend over in the mornings. My shoulders and hips felt cushioned as I sank in the mattress, but it felt boyant at the same time and supported my low back so that I stayed in spinal alignment.  I want to feel that way every night and every morning.  But we've spent so much money thus far that we can't simply order a new mattress.  (We'd also purchased a pricey adjustable base for almost $3000, plus the $1200 Simmons mattress and the two toppers). 

Do I need an intermediate layer that is Medium as a transition between the super firm and the cushion on top to keep from bottoming out?  If so, should that be 2" or 3"?  If I had to guess, I have enough cushion on top, but nothing other than cushion on top and painfully firm on the bottom.

Does it sound logical to go with a 32 ILD or a different ILD as a middle layer under the two toppers?  Something different?  What thickness should we select? 

I'd appreciate any and all suggestions.  I've been up since 3:45 this morning, because I couldn't stay in bed any longer. I really want my life back. 

Thanks!
