Easy to use and clean: The full-buffer design and flexible structure allow quiet lifting and lowering of the sofa. This delivers smooth, stable movement without damaging the furniture. The smooth surface and simple construction provide easy access to the components. Wipe clean to keep it looking like new for years. Durable and reliable construction: The hydraulic under-bed lift mechanism is made from solid cold-rolled steel plate for high load capacity, rust resistance, and deformation resistance, ensuring long life. Connections use steel wave rivets that are highly wear-resistant, open and close slowly, and cushion the unit without pinching. Increases storage capacity: The frame hinge transforms space under the bed or sofa into usable storage, helping you reduce clutter and make the room feel larger. Space-saving and versatile: The pneumatic-hydraulic bed lift hardware is ideal for lifting mattresses, boards, or bed frames on sofas and beds, providing substantial under-bed storage to maximize room usage. Use scenarios: - Small apartment or studio: store seasonal bedding and luggage under the bed for easy access. - Living room with a sofa bed: create hidden storage for remote controls, blankets, and magazines. - Guest room or children's room: keep extra pillows, towels, toys, or linens neatly out of sight but readily accessible.
