It is the BEST memory foam I’ve had yet! I woke up after night 1, my hips were not hurting, my lower back wasn’t hurting. I came from a firm mattress w 3” gel memory foam topper and I thgt it was better then most, but still woke up sore, thg it was from old age (I’m 38 in okay shape) and being a mom of lil ones (4yr, 5yr, 9yr). To actually wake up NOT complaining how bad my back hurts and I need a massage from my hubby..... my HUSBAND was beyond happy LOL
