Protect a new mattress without losing the soft feel: the Cariloha Signature Jersey Mattress Protector pairs a stretchy bamboo viscose and spandex jersey top with a waterproof TPU polyurethane layer. Protection covers five sides, the top and all four sides, against spills, sweat, and accidents, and the fabric stays quiet with no crinkle or bunching under your sheets. The fit comes from Cariloha's Corner Active Bands on each corner and the Perfect Bed Border elastic that runs the full edge, so the protector hugs the mattress like a fitted sheet and does not creep. The face fabric is 85% viscose from bamboo and 15% spandex, which Cariloha describes as thermal regulating and naturally resistant to odors and allergens. Machine wash cold, tumble dry low. Available in Queen and King in white, it is the right first add-on for any new mattress and is required to keep most mattress warranties valid.
