With this memory foam mattress, your entire body is supported in the correct anatomical position, which allows your spine to experience the best natural sleeping posture. The reduction of pressure points, will decrease the need to toss & turn during the night, providing a more restful & undisturbed sleep. Memory foam was originally developed by NASA to relieve pressure build up from the G-force experienced by astronauts during lift off. Now you can not only experience these pressure relieving qualities while you sleep, but also, as memory foam absorbs motion, you will not feel your partners movements, allowing you to sleep more soundly. Constructed from our Dual Layer memory foam system for extra performance, The Classic Ultra also incorporates a unique double ventilated foam base. This ensures twice as much as airflow for an even cooler sleep. Its also a deeper, more luxurious mattress, but still with exceptional supportive qualities & at a fraction of other similar known brands. What is Outlast?
