The Classic Custom Organic Mattress is ideal for sleepers ready to experience the benefits of a fully customizable organic sleep system.

Built with 8 inches of pressure-relieving GOLS-certified organic latex, the Classic features Obasan’s modular multi-zone design, allowing your mattress to be tailored based on your weight, sleep position, and body type. A firm latex base provides consistent support, while adjustable zoning improves alignment and reduces pressure at key areas of the body.

Finished with a removable organic wool and latex topper, the Classic delivers balanced comfort, breathability, and flexibility, making it the perfect introduction to customizable organic sleep.

Sleepers who want a customizable sleep with a firm base layer for convenient support.

For best performance, your Obasan mattress should be placed on a firm, supportive foundation with built-in breathability, such as wooden slats or a ventilated platform base. See our Obasan Foundations.

Slatted Base/Foundation

We recommend a slatted mattress base or foundation with:

  • Metal or wooden slats spaced no more than 3” apart
  • Slats that are  2” - 6” wide
  • A centre support bar running vertically down the middle of the frame
  • One or more centre legs to further support the centre beam. This becomes especially helpful for larger mattresses (Queen, King, or California King).

Solid Wood Base/Foundation

If your foundation has a solid wood surface, it must include ventilation for airflow. We recommend: 

  • Vent holes approximately 1” in diameter
  • Spaced about 12-15” apart

 ensure it has holes or vents for recommended breathability. We typically recommend holes of about 1" diameter every 12-15" apart.

*** Please refer to our diagram in the product images for visuals.
