Metal sofa legs with good stability require good structural design
Stable geometric shape
Triangular, trapezoidal, cross-shaped, X-shaped and other structures: Utilizing geometric principles to disperse pressure, for instance, the triangular support feet are fixed at three points to form a stable plane, and the cross-shaped crossbeam enhances the lateral tensile force.
Conical or trumpet-shaped base: The design that is narrower at the top and wider at the bottom increases the contact area at the bottom, lowers the center of gravity, similar to the principle of a "non-toppling doll", and reduces the risk of overturning.
Integral molding process
Give priority to choosing sofa legs that are integrally cast or seamlessly welded to avoid the decline in stability of the spliced structure caused by loose interfaces.
If it is a composite structure, the connection points should be fixed by methods such as embedded mortise and tenon joints or bolt penetration, rather than simple spot welding or glue bonding.
The welding or connection process is firm
The weld seams are uniform and full, without defects such as false welding, missed welding, or bubbles. The welding points have been ground to enhance the connection strength (the quality can be judged by tapping the weld points and listening to the sound; a clear and solid sound indicates good quality).
The sofa legs fixed with screws are made of stainless steel screws and anti-loosening washers. The holes are precisely matched to avoid shaking caused by loose screws.
