I ordered a king. It was between going broke for an organic/latex mattress or spending more on quality bedding and furnishings. I'm very happy I made this decision. The reviews here were great, the esthetic was great, and the eco-certification was enough to satisfy me for the price. I ordered the "4in instant foundation" to add height to the mattress. This arrived quickly, boxed nicely, it wasn't unreasonably heavy, and expanded in minutes. It's the most comfortable mattress I've been on since our honeymoon and the price is just unbelievable.
