The mattress is way to firm. I am 150+lbs and dont sink in it at all. I ordered it for my 4 year old son, so his 37lb little body just rests on top of it. He might as well sleep on the floor.
We love this mattress! I was a bit hesitant based on some reviews of odor or that it was hot. Neither was true for us. We aired it out for a few hours and slept on it that night. It is super comfortable and was easy to order and unpack. I highly recommend Tuft and Needle!
