Green Sleep S-300 Foundation

S-300 Foundation

Organic Mattress Foundation from Green Sleep

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 organic velour, a Green Sleep signature feature, which matches our entire line of mattresses to perfection.

  • Covered in 100% organic cotton and pure virgin wool
  • Frame built entirely from solid, untreated poplar
  • Individual and interchangeable dowel anchors for adaptable support
  • 7" high (without legs)
  • The foundation can be used within an existing bed frame or with Green Sleep legs (10")

Green Sleep is more than revolutionary thinking. It's a good night's sleep, guaranteed. More than just high-quality mattresses, Green Sleep is a healthy balance between science, nature and common-sense ergonomics—a natural choice for comfortable, restorative sleep.

Based on more than 30 years of scientific research, Green Sleep is a concept born of necessity; the better we sleep, the better we feel. That's because undisturbed sleep refreshes, restores and rejuvenates.

Q & A

Organic mattresses are derived solely from natural materials: materials that are organically grown and processed. Conventional mattresses, on the other hand, are composed primarily of man-made materials derived from nonrenewable resources such as natural gas and petrochemicals. Plus, the cover fabrics and paddings of conventional mattresses contain fire retardants and other chemicals.
