Hey there,
So I'm 5'10", 220lbs. Mostly side, sometimes back sleeper.
I'd been sleeping on a medium budget foam (not even memory foam) mattress for about a decade, when I decided I needed something new.
I'd been having upper back problems due to scoliosis, which the doctor recommended a firmer mattress for. Great. I hear great things about latex mattresses and decide to go with Avocado Green (what had been the Standard when I bought it, now is called the Medium).
Good news, it's been great for my upper back. Solid firmness has helped up there a ton.
Bad news, after 4 months it's been absolutely killing my lower back and hips. I gave it time for my back to adjust and any break in to happen, but it's just been getting worse. Tightness, pain, and finally spasming. I'm relegated to the couch now.
It think down near my lower backs and hips I can feel it pushing up at the small of my back, which combined with the firmness seems to be causing my problem.
I threw on a cheap 3" memory foam topper I had laying around, but that did not help. Then again, it was quite old.
So this mattress needs a return, but what to replace it with?
A few thoughts:
I've heard Talalay might be better for side sleepers, and I keep hearing good things about Engineered Sleep? But it also could be that the pressure that latex provides just isn't right for me.
It's not Latex, but I also hear good things about Nolah for heavier types like myself.
I don't like the sinking feeling of purely foam mattresses.
Any other thoughts? I couldn't find anything zoned in a way that seems to fit what my spine seems to be demanding.
