I ordered the Core Twilight and upgraded to the GlacioTex 2in plush topper. Seems like the best bang for the buck (vs. the luxe) because the lack of the stiffer springs in the middle might soften the bed ever so slightly to help accommodate side sleepers. I’m a stomach and side sleeper at 6ft 200lbs and I was worried that it might be too stiff. Thanks for providing some clarify 🙏
