The Lockable Gas Spring for Sofa is a critical component for modern reclining furniture, enabling smooth, infinite backrest adjustment. Unlike traditional ratchet mechanisms that only offer fixed positions, our gas springs allow users to lock the sofa backrest at any desired angle for personalized comfort.
Designed specifically for living room furniture and home theater seating, Colewell's lockable struts prioritize silence and ease of use. The internal valve system creates a secure lock to support the user's weight while allowing for effortless adjustment via a simple lever or button release.
| Locking Force | 100N - 1000N. High locking force ensures the backrest stays firm even when a heavy user leans back fully. |
| Material Build | Cylinder: Black Powder Coated Steel (blends with furniture mechanics). Rod: Hard Chrome Plated or Black Nitrided for sleek aesthetics. |
| Locking Types | Rigid Locking: For firm, upright support. Elastic Locking: For a softer, cushioned feel in lounge modes. |
| Operation | Release Pin: Short-travel pin designed for cable or lever actuation. Noise: Engineered for near-silent operation (<30dB). |
Stop the backrest exactly where you want it. Whether upright for reading or fully reclined for napping, the lockable gas spring holds the position securely.
We use premium hydraulic oil and optimized piston valves to eliminate the "hissing" sound and jerky movement often found in cheaper struts.
Includes an overload protection feature. If excessive force is applied (e.g., jumping on the sofa), the valve yields slightly to prevent bending the rod or breaking the frame.
• Fittings: Metal eyes or clevis forks to match your recliner mechanism.
• Size: Compact lengths (e.g., 150mm stroke) to fit inside low-profile sofas.
Backrest Control: Enables users to push back to recline and lock the position simply by releasing the side lever or button.
Multi-Position Lock: Allows the sofa to function as an upright seat, a lounger (45°), or a flat bed (180°), locking securely in each mode.
