@37712 Never tried but Andrew Huberman have sponsor called helixsleep https://helixsleep.com/pages/audio-partner/?promo=huberman
I can have it delivered, I can pick it up, I dont like pure memory foam mattress bc I have one and it was not really that good, I always had curvature problems when sleeping on it and not that it is 6 yrs old I dont want another one like it, I believe I will take your advice and get a firm one but springs and possibly a layer of memory foam on top
