Those are definitely the majors. But I would also include a couple of others. Noise is something every bed should be without. Another is moving response. When you move in bed, the surface literally follows you around. Its reaction to your moves can range from 'bouncy' to 'tranquil'. Foam is quiet, and with its lack of moving parts and accompanying inertia it reacts very gently to body movement. In summary, those are the sleep benefits that quality sleep products should offer. They may, or may not line up with the attributes as seen by the merchandiser, or the consumer. The uncomfortable, overly firm bed is still very much in vogue. Consumers don't really know what to look for in sleep products. They buy what they are sold. The onus of providing a better quality sleep lies with sleep products manufacturers, like Foamite, and their deeper understanding of true sleep attributes, and the ways to meet them.
