Foundations - S-300 Natural dyed linen

This foundation is constructed using pure, untreated, dried poplar. Our wood is locally harvested from sustainable forests. Our foundations are also assembled without the use of any glue. For the S-300, we only use dowels, which maximizes the complementary, adapted support in complete harmony with the mattress for optimal ergonomic results. The dowels are flexible and supported by independent recycled polymer anchor pins and with variable firmness, according to the part of the body they support. This flexible dowel system also allows excellent air flow; ideal for natural rubber mattresses. This foundation is also covered in a natural dyed linen , a Green Sleep signature feature, which matches our entire lines of mattresses to perfection.


  • Covered in Natural dyed linen and pure virgin wool
  • Frame built entirely from solid, untreated poplar
  • Individual and interchangeable dowel anchors for adaptable support
  • 6 3/4” high (without legs)
  • The foundation can be used within an existing bed frame or with Green Sleep legs

How you sleep is just as important as why you sleep. That’s because your body is a complex machine that can be easily disturbed by noise, pain or other stimuli during the sleep cycle. And one of the predominant causes of sleep disruption is painful pressure points. Although painful pressure may originate with an ongoing health issue or a recent injury, it is largely aggravated by the inability of a mattress and foundation to maintain linear and lateral support for your spine, hips, and shoulders.
