Its kind of funny because in the winter here in Ohio it would be really hard when you first get in it and it took maybe 15 minutes until it heated up enough for it to do its trademark contouring to your body. So you'd just be sleeping in basically a ditch until it heated up enough to actually do it's thing. So I'd always have to re-adjust (and generally move elsewhere in the bed because there is a giant dent where I was previously) and then fall asleep again. Then in the summer it would be like sleeping in an oven. And then trying to bang. Oh god. Doing anything cowgirl is like fucking in quicksand. Doing missionary has no bounce-back which makes that position weird too. Even doggie is a pain because your knees sink hella deep.
Overall I must be that 1 out of 100 that would not recommend the mattress
