This mattress is in total about 7" thick with two 3" natural latex cores encased in a wool and organic cotton damask quilted zip outer.
This mattress is ideal for those who prefer a supportive feel from their mattress without the pressure points possibility from innersprings. The zip outer Harmony has two 3" cores which also allows for a more customized feel.
With the zip outer Harmony, using the Extra Soft as a top layer is not recommened unless this mattress is being used for a guest bed, child, or lighter weight adult(115lbs and below). This is because for most adults, this combination will not properly support the body long term.
This mattress is shipped in individual pieces to allow for a lower shipping cost and easier handling. It is very simple to put the mattress together, instructions are included when shipped. If one would like the mattress pre-put together, there is an additional cost, please contact us for a quote on that cost.
If one ever wants to add some softness to this mattress we recommend a natural latex extra soft rubber topper which can be found in our organic bedding section. Additionally, for protection from spills and such, we highly recommend the organic cotton quilted pad be used with this or any of our mattresses. This pad can be found in our organic bedding section also.
