【3-in-1 Folding Sofa Bed｜5-Position Adjustable Backrest】This versatile folding furniture combines three functions—sofa, recliner, and single bed—with a 5-position adjustable backrest that supports everything from upright sitting to full flat lying. The intuitive folding mechanism allows smooth transformation between modes, offering a flexible space-saving solution for compact living. 【Ergonomic Support & Removable Cushion】The backrest and seat are filled with high-density rebound foam and designed with ergonomic curves to provide even support for the lower back and spine. The outer blue fabric cover is removable and machine-washable, making maintenance easy and keeping the piece looking fresh. 【Sturdy Metal Frame & Smooth Adjustment System】Built with a reinforced steel tube frame and a reliable friction-based positioning system, this sofa bed maintains stable alignment in sofa, recliner, and bed modes. The simplified mechanism ensures ease of use while delivering consistent performance and durability. 【Modern Blue Design｜Multi-Scenario Adaptability】The clean blue finish and streamlined silhouette blend easily into modern homes, offices, or guest rooms. Whether used for overnight guests in the living room, extra sleeping space in a bedroom, or a lunch break nap at the office, it integrates seamlessly into various environments. 【Easy Assembly & Compact Storage】The main structure comes pre-assembled, with only minor parts like armrests requiring simple attachment. When folded, it measures less than 12 inches thick, allowing it to be placed against a wall or stored in a corner to maximize floor space.
