Wood Foundation with Organic Cotton Description

The Wood Foundation slat system is hand-crafted from domestically grown organic cotton. The box and wood plank construction is completed using FSC certified hard woods. Slats are spaced 3" apart to properly support any mattress. Our organic, pure & local ingredients have no pesticides, bleaches or dyes that's why our mattresses and foundations are all natural & all healthy.

Perfect for those who need a boxspring for their frame or want to add height to their mattress.
Perfect for those who have an older bedframe that doesn't have slats.
Now you'll have slats built right into the foundation for the perfect height and support.

Wood Foundation with Organic Cotton Care

Vacuum and Air – vacuum and/or air regularly which helps the natural fibers breathe.

Stains – Are best removed by simple spot cleaning. Apply a solution of 1:3 parts white distilled vinegar and water (you may also use a natural detergent to spot clean). Spray the solution on the spot, then allow to dry completely. If possible, moving the mattress into the sun to dry is most advantageous.
