Proudly Made in America, this firm mattress is covered in a luxurious stretch knit fabric made from natural fibers. The yarn in our ticking is made from 100% bambusa natural pulp fiber. These are extremely soft fibers that are naturally anti-bacterial, anti-fungal, and are non-allergenic. This makes it an excellent sleep surface for allergy sufferers. These fibers have excellent ventilation and moisture absorption qualities, so it stays cool, dry and fresh for the life of the mattress. High Density surface quilt foams will cushion and support every part of your body, improving circulation at the shoulders, arms and hips while resisting body impressions.
