- Deep Comfort Profile : Expanded layer height enhances pressure relief, motion isolation, and body contouring.
The Grand Custom Organic Mattress represents the pinnacle of Obasan’s craftsmanship, customization, and unmatched comfort.
Built with 12 inches of pressure-relieving GOLS-certified organic latex and finished with a luxuriously thick 3.5-inch organic topper, the Grand offers a deeply cushioned, cloud-like sleep experience without compromising support.
The Grand’s added depth and layers allows for exceptional adaptability across body types, sleep positions, and comfort preferences. The expanded profile enhances pressure-point relief, improves motion isolation, and creates a sense of weightless relaxation night after night.
Designed for sleepers who want nothing less than the most immersive organic sleep system available.
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.
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
Please ensure it has holes or vents for recommended breathability. We typically recommend holes of about 1" diameter every 12-15" apart.
