This is our top of the line, one sided, box top mattress. 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 4” of plush natural latex. We top of the mattress with an organic cotton quilt. These materials create an ultra-plush feel without losing support. Because latex is an energy foam, it proves great support and pressure relief. We nicknamed this mattress “The Owner’s Bed.”
