This set holds two pillow protectors constructed from quilted polyester material to block liquid contact with inner pillows. An envelope-style side opening simplifies loading pillows and keeps inserts fixed during rest hours. Uniform stitched padding creates extra layered texture without bulky thickness. The woven polyester material supports regular machine washing while preserving its stitched structure long term. Designed to match standard pillow dimensions, this protector set fits household bedrooms and hotel guest room bedding arrangements.
