This two-piece pillow protector is constructed from thick quilted polyester fabric with water resistant performance for daily use. It adopts an envelope side opening design to simplify putting on and taking off inner pillows, keeping cushions steadily positioned all night. The padded surface delivers a gentle, cozy touch for resting, while solid woven construction maintains its form and texture after multiple laundry cycles. Made to match queen sized pillows, this set works nicely for residential bedrooms and hotel accommodation spaces for long-term pillow care.
