The armrests adopt a smooth and rounded integrated design with flowing curves. The lines are natural and soft, perfectly fitting the natural curve of the arm when placed. The interior is filled with high-elastic and soft foam, providing both a soft touch and solid support. The backrest is not hard and the support is not collapsed. Whether it is for daily desk work with elbows resting, casual arm-crossing relaxation, or free and relaxed limb stretching, one can enjoy a gentle and stable support and care. Even when sitting for a long time watching TV or chatting and resting, the arms and shoulders and neck can be relaxed without any burden. The bottom of the sofa has been upgraded with anti-slip protection design, firmly adhering to the ground and not slipping, effectively avoiding daily sitting, getting up and shifting, and shaking. The modules are closely connected with special fasteners, the combination is stable and not loose, the overall structure is solid and stable, making it safe and reassuring for daily use. It is stable and does not shift when sitting and leaning, and the placement is more convenient and worry-free.
