- Material and comfort: The mattress cover is skin-friendly knitted cotton fabric. The mid-layer uses microfiber-down filling, providing good support when you lie on the mattress and helping you sleep more comfortably. - Ergonomic design: The mattress conforms to the human body shape and supports proper neck and spine alignment. It can significantly improve sleep and relieve most back pain caused by stiffness, enhance sleep posture, and relax the spine for orthopedic function. - Care and setup: Please sun-dry the floor mattress first; it will recover thickness more quickly in sunlight. Note that the futon mattress is compressed into a storage bag for transport. Please allow 2-3 days for thickness to restore. - Versatile uses: It can be used as a bedroom futon, living room futon, mat, floor mat, sleep surface, tent mat, guest mattress, or Japanese bed mat. It can also serve as a play mat or floor cushion bed. Take it in your car when you travel, making it a good companion for your family. - Use scenarios: - In a spare or guest room as a comfortable floor bed or futon. - For camping or travel as a sleeping mat inside a tent. - In a family living area or playroom as a soft play mat or floor cushion bed.
