❓ Common Problem: Do Modular Sofas Come Apart Easily?

Problem: Many buyers worry that modular sofas might shift or separate during use.

Solution: Modern U-shaped sectionals now use improved interlocking connectors that keep modules firmly in place. Most 2025 models feature hidden clamps, locking brackets, or Velcro strips, which prevent slipping — even with daily use. As a result, you get both flexibility and stability without constant readjustment.
