Sleep Science 9" Natural Latex Split-King Mattress with Adjustable Base
The Sleep Science 9” Natural Latex is truly natural, and it is a natural fit with Sleep Science adjustable base. This luxurious latex mattress has been developed for those that seek a more natural sleeping environment. This mattress is comprised of 2 layers of natural latex. The top 3 inches has been crafted to create a soft initial feel with the slight bounce of latex. The next 6 inches of natural latex is made to offer optimal support, while still allowing for comfortable conformity to the body. Natural latex is derived from the rubber tree and is transformed into the most durable sleep surface available on the market today. These latex layers are made using the Talalay method to create a durable, pressure relieving sleep surface. This natural latex mattress is resilient, supportive and conforming. The breathability of natural latex is unrivaled and keeps the body warmer in the winter and cooler in the summer. The feel of latex is plush, yet offers instantaneous recovery and support. The mattress cover is made of 37% organic cotton and the fire retardant properties are chemical free. The mattress cover is quilted using wool and an inherent fire retardant fiber in order to pass the stringent 1633 and 1632 Fire retardant certifications. The Sleep Science Natural Latex mattress is all natural for those seeking a luxurious sleep experience in a healthier sleep environment.
The adjustable base is made of reinforced steel and slips easily into an existing bed frame or can be used as a stand-alone bed. It features one of the quietest motors on the market and a sleek, stylish, streamlined design. The adjustable base also has a massage feature that is available on the head, feet or both.
