Key Features of Our pull out sofa bed mechanism with wheels

• 5.45 kg Solid Carbon Steel Frame: Heavy-gauge stamped steel plates with solid steel center pivot rivets withstand daily commercial guest use without sagging.
• Floor-Protecting Polyurethane Rollers: Integrated caster wheels glide smoothly across hardwood, ceramic tile, and carpeted floors without tracking or surface gouging.
• 65Mn Spring-Assisted Scissor Lift: High-tensile manganese counterbalanced springs offset platform weight, enabling effortless one-handed elevation from trundle to bed mode.
• Over-Center Mechanical Self-Locking: Rigid geometric stop linkages secure the elevated platform in place, preventing accidental collapse under sleeping loads.
• Anti-Corrosion Matte Black E-Coating: Industrial electrophoretic finish meeting ISO surface standards protects pivot pins and linkage brackets against domestic humidity.
