Overview of Mechanical Convertible Systems
A sleeper sofa's longevity depends fundamentally on the gauge, pivoting geometry, and counterbalance of its steel mechanism. Foshan Demi Furniture engineers three proprietary mechanical systems:
| Mechanism Type | Steel Gauge & Coating | Cycle Rating | Best Application |
|---|---|---|---|
| Cold-Rolled Steel Pull-Out Trundle | 2.0mm high-tensile steel, electrostatic powder coat | 10,000+ Cycles | Modular sectionals & family living rooms |
| Bi-Fold Trampoline Grid Base | Heavy-duty tubular steel with polypropylene deck | 8,000+ Cycles | Hotel contract guest rooms & suites |
| Multi-Stage Click-Clack Hinge | Stamped hardened carbon steel (3 positions) | 12,000+ Cycles | Compact studio loveseats & futons |
| German Okin Motorized Actuator | UL/CE certified dual electric linear motors | 15,000+ Cycles | Luxury executive power reclining sectionals |
Anti-Pinch Safety & Counterbalance
All Demi mechanism hinges incorporate recessed scissor joints to eliminate pinch points. Heavy-duty torsion assist springs reduce opening force to less than 35 Newtons, enabling smooth, one-handed operation by hotel guests.
