The total length of the side guardrail is 1150mm, and it is a D-type aluminum alloy handrail with a hardened surface treatment. Equipped with 5 stainless steel guardrail pillars, the upper and lower connectors are made of one-time stamped steel parts with a thickness of 2.5mm. The switch is carefully designed to ensure long-term safety, and is also equipped with anti loosening fasteners that are wear-resistant and non deformable. It can be retracted and placed flat, slightly higher than the bed surface when retracted, to prevent the mattress from shifting.
