Comfort	Proprietary foam features exceptional pressure relief combined with enhanced airflow properties. Precision-contoured 3D geometric surface provides targeted, self-adjusting support for different parts of the body.	Ventilation is the key to sleeping just right - not too hot, and not too cold. Purple achieves the ultimate sleep comfortability by combining a totally new material with a totally unique design. Purple remains temperature-neutral so you don't sleep hot and sweaty at night Purple's column design allows air to flow freely, preventing moisture trapping, extending the life of the mattress, and providing cleaner, more comfortable sleep. Thanks to the free air flow design and patented polymer materials, Purple naturally sleeps much cooler than memory foam, latex, and other mattress technology.
Support	The foundation of the MOLECULE mattress. An ample 7” of firm support fosters healthy spine alignment. Breathable materials promote even more airflow and heat transfer.	A revolutionary mattress designed for just about everyone. It's designed to not only help you get better sleep, but to soothe joints, release pressure on the hips and shoulders, and support the neck and back. It's designed to make bedtime the highlight of your day! The Hyper-Elastic Polymer Purple is a pressure-releasing material. This material is organized in a grid formation, which creates walls that can support or fold, depending on how much pressure it receives. It's durable enough to last decades so you won't develop a body impression. And it buckles under specific pressure, which provides excellent motion isolation so you don't feel someone else move in the bed.
