DualSided Comfort Version A features thickened artificial lambskin for warmth, while Version B offers a skinfriendly fabric for a softer touch. This dualsided design provides comfort across seasons and accommodates different user preferences, improving your sleep experience. Quilted Design for Support The mattress employs a square quilted design with three layers: brushed fabric, quilted insulation, and down filling. This layered structure conforms to the body's natural curves, helps alleviate fatigue, and delivers solid support. Innovative Comfort Solution This traditional futon mattress can function as a mattress protector in student dorms or as a camping mattress. Its ability to distribute body weight evenly and its nonslip features help maintain a stable, restful sleeping surface. Convenient Storage and Portability The Japanese bed roll design makes it warm, flexible, and adaptable to body contours. With quilting technology, it is lint, nonslip, wearresistant, breathable, and moistureabsorbent without pilling.
