Comfort Pure Boulder Stow

This mattress is designed to be exceptionally firm, mimicking traditional Japanese shikibutons. It provides a dense, supportive surface with very little sink, which is ideal for those who prefer sleeping on a flat, stable foundation rather than a plush, contouring one.

Yes, it is specifically designed for floor use, making it an excellent option for minimalist setups or guest arrangements. However, because it is only 3 inches thick, you may want to pair it with a tatami mat or a rug if you are placing it on a hard surface to provide a bit of insulation and airflow.

This mattress is constructed without any chemical fire retardants. In certain jurisdictions, manufacturers are required to obtain a prescription from a medical professional to sell non-flame-retardant bedding directly to consumers.

Because this mattress is made of 100% natural, unprocessed cotton, it will compress over time with regular use. We recommend flipping and rotating the mattress regularly to ensure even wear and to help maintain its loft and shape.

Generally, no. Due to its 3-inch profile and firm, dense cotton construction, it lacks the pressure-relieving cushioning required for most side sleepers. It is best suited for back or stomach sleepers who prioritize spinal alignment and a firm surface.

It arrives vacuum-sealed for protection during transit. Once you open the packaging, the cotton will begin to expand, but it may take a few days of use for the mattress to fully settle into its intended shape and firmness.
