This Washington‑style quilted mattress protector fits snugly like a deep pocket fitted sheet around small double mattresses (approximately 120 × 190 cm), stretching around the sides. Featuring a soft poly‑cotton top with a TPU waterproof backing, it repels spills and perspiration quietly—no crinkling noise to disturb your rest. Its hypoallergenic, breathable design helps shield against dust mites, allergens, and moisture for a healthier sleep surface.
