The comfort layers of a mattress are at the top of the mattress, and can be made from polyurethane foam, memory foam, gel, micro-coils, latex and/or natural and artificial fibers. These are the "padding" layers that are designed to support your body's natural curves while applying pressure relief.
In our comfort layers, we use GOLS organic certified Dunlop latex and GOTS organic certified wool. Our ticking is made with GOTS organic certified cotton for a natural and luxurious finish.
The support layers are generally found at the bottom of the mattress, and are often made with firmer polyurethane foam, polyfoam, latex and/or a Bonnell, offset coil, continuous coil, or a fabric encased (a.k.a. Marshall or wrapped) innerspring unit. These are the core layers that are designed to provide proper support for your shoulders and hips and reinforcement for the edge, while reducing motion transfer, flexing, and enabling the mattress to "breathe" naturally. They are the core structure of the mattress.
Avocado Green Mattresses use a fabric encased innerspring unit, over a firm layer of GOLS organic certified Dunlop latex.
