The SomnoMed Herbst Advance Elite™ is designed with superior flexural strength, which is achieved by milling it from one piece of pre-cured PMMA.
It has all the patented strength improvements of the Herbst Advance®, and it’s made so well that SomnoMed offers free replacement for 3 years if it breaks. Additionally, it comes with a Bflex soft inner liner that provides unmatched comfort and retention.
