Loooooove my mattress! I haven't been this happy with a bed in a long time. Half the battle is the frame, so choose that wisely (I chose Zinus for my frame as well), but I am loving my mattress and frame, and not dealing with a box spring. I am 6' tall and too many lbs heavy, and the 8" mattress is plenty thick enough for me. I never feel like I am sinking into it, or pressing onto the frame. I feel supported and comfortable! I've had my mattress and platform for about a month and still brag to my friends that I have the most comfortable bed in the world.
