Got a saggy recliner or sofa that's not working like it used to? These Yoogu tension springs might be exactly what you need to bring your favorite furniture back to life! This 8-pack of replacement springs measures 1.9 inches overall length with a 1.75 inch inside hook to inside hook measurement. With a coil diameter of 12-14.3mm and 12 turns in the coil body, these black mechanism springs are built to handle the tension and wear that furniture mechanisms require. They're perfect for replacing worn-out springs in recliners, sofas, and other furniture where the mechanism needs that extra assist to function properly. The quality is solid - these aren't flimsy springs that will stretch out quickly. They provide the right amount of tension to help your recliner lock into position smoothly and stay there. Installation is straightforward if you're handy with basic tools, though having a helper makes the job easier since springs can be tricky to work with. Having 8 springs means you can replace multiple at once or keep extras for future repairs. There's nothing more frustrating than furniture that doesn't work right, and often it's these simple tension springs that make all the difference. Whether your recliner won't stay reclined, your sofa mechanism feels loose, or you're doing furniture restoration projects, these springs deliver the reliable performance you need. Bring that comfortable furniture back to its former glory without spending a fortune on professional repairs or replacement furniture. Sometimes the simplest fixes make the biggest difference!
