Made with Essentia's Natural Memory Foam the Beausommet provides added mid-body support. For people who prefer a firmer bed surface or people who require mid-body support. Firmer than our Dormeuse mattress, the Beausommet is designed for mid-body to bottom-heavy body types or people who just prefer a firmer, yet pressure relieving mattress. A latex lumbar support feature is fused into the mattress preventing the mid-body from sinking in too deep. This added support also contributes to proper spinal alignment for mid-body to bottom-heavy body types.
