Part of our top-of-the-line one sided series. The mattress finishes 17” deep. It consists of a heavy-duty spring core, packed with organic cotton batting, and natural latex for the lumbar support. We then layer a micro coil spring unit above the core and top it with 2” of plush natural latex. We top off the mattress with an organic cotton quilt. Because latex is an energy foam, it provides great support and pressure relief. Using these materials creates a medium plush feel with excellent support.
