Why a protector is not optional
Almost every mattress warranty in the industry, ours included, is voided by staining. Not by wear, not by softening — by a visible stain. A single spilled glass of water, a sick kid, or an unlucky night can end a ten-year warranty on a mattress that is otherwise perfectly fine. A protector is the cheapest insurance in the bedroom, and it is the one accessory we recommend adding on night one rather than later.
The second reason is biological. A mattress absorbs roughly a liter of moisture per person per week through ordinary perspiration, along with skin cells that feed dust mites. A waterproof barrier stops all of that at the surface, where it can go in the wash, instead of letting it settle into the foam and coil layers where it cannot be cleaned.
