Not as firm as we were hoping. Also the jury is still out as far as being too hot to sleep in. Since it is winter our room is much cooler than normal at night, however it already seems warmer than our previous mattress.
I have slept better since mattress arrived than I have In years. It is subtle and I cant say why. I know I dont cave into the middle of the bed from my husband’s weight. It is not too firm nor is it soft. It just makes my body comfortable to sleep
