💡 How do I choose the right extension spring for a lifted sofa mechanism You can grab these handy aftermarket parts that align perfectly with standard chassis brackets and pivot points. Measure the full hook to hook distance to avoid mismatched tension that stops the seat from locking flat. Count the internal winding count so the steel stretches gradually without hitting hard stops too soon. Pick heavier wire gauges to handle repeated folding cycles without losing their original bounce factor.
