Ergo Concept Nine is the North American version of the original European Green Sleep mattress. A unique centre layer is split into three individual plates of natural rubber. This core may be arranged with a soft, medium or firm plate of rubber to achieve perfect ergonomic alignment for virtually any body type or sleeping position.

The most common configurations are a soft plate for the shoulders, and medium plate for the hips, or a medium zone for the shoulders and a softer zone for the hips. A firm plate is also included, although usually this is located at the foot end of the bed. The firm layer could be used for the shoulder or hip zone, however most body types and sleeping positions would not require such a firm latex in these areas.

North Malaysia 600

North Malaysia 600 is Green Sleep's own exclusive proprietary process. Green Sleep's Natural Rubber cores are derived from their very own tree farm. These trees have been bud grafted to create the North Malaysia 600 seed which in turn produces the purest most elastic rubber on the planet. No latex or synthetic fillers are added to core production.

A side-long view of the Ergo Concept. The bottom 2" layer is always firm, while the top 3" layer is always extra soft. The central ergonomic layer is split into three zones, each of which may be soft, medium or firm for precise, targeted support and pressure relief.

The result? Firm where you need it, and soft where you want it.

  Zoned Latex Mattress

Green Sleep employs a fabulous cotton velour ticking to finish off the mattress. The cotton is hand picked, and organic. This cover is then lined with layers of pH neutral Texel wool, to create a fully breathable mattress capable of wicking away moisture and providing temperature regulated sleep.

Customization & Assembly

Many of our mattresses require some basic assembly when they arrive to you. If we're delivering locally where we have a showroom, this work is performed by our delivery teams. If we're shipping elsewhere, this assembly procedure is something you'll want to be prepared for, although the actual process of assembly is very straight forward.

There are six significant benefits to having a mattress which is delivered in smaller pieces:

  1. Instead of moving a large, awkward mattress in one giant piece weighing as much as 300 lbs, instead the mattress arrives in a few boxes which are much smaller and easy to handle.
  2. The mattress will easily find it's way up tight staircases. We often deliver king mattresses into spaces where a regular king simply wouldn't fit.
  3. Many of our mattress models may be customized with different firmness options for each sleeping partner. By having a mattress made with separate components, we're able to fine tune the comfort to a very precise degree of success.
  4. If your comfort or support needs change in the future, you can either re-arrange the components already in your mattress, or we can replace them with different components offering different comfort and support characteristics.
  5. Thorough maintenance: Only by accessing the inner support layers of the mattress and flipping these layers can we truly maintain the mattress correctly over many years. Rotating a traditional mattress merely helps the top comfort layers settle more evenly, where-as flipping the support layers actually revitalizes the entire mattress.
  6. Individual layers may be replaced should they prematurely wear out before other mattress components. Also, no more guessing about where the wear and tear are taking place in your mattress. By taking the mattress apart, we can isolate the problematic component to easily solve common mattress wear issues.
