Modular and sectional sofas are great for flexible living spaces, but they often come with one small frustration: the pieces tend to slide apart. Whether you’re dealing with a large sectional or a smaller 2-piece setup, keeping your sofa together is key to both comfort and style. In this guide, we’ll explore four effective ways to keep your modular or sectional sofa from separating—plus the pros and cons of each method.
How to Keep Your Modular or Sectional Sofa Together

Solution 1: Hook & Loop Cinch Straps for Sofas
Hook & loop cinch straps are adjustable straps that use hook and loop fasteners (like Velcro) to keep modular or sectional sofa pieces tightly bound together. These straps are wrapped around the sofa legs or frame and cinched to prevent movement. They’re a simple, tool-free solution favored for their ease of use.

Pros:
- Easy to install and remove—no extra tools required
- Compatible with most sofas that have legs
- Nearly invisible once installed, preserving your sofa’s appearance
Cons:
- Not suitable for legless sofas or low-profile designs
- The straps may wear out over time from regular use
- Dust buildup under the sofa can reduce the Velcro’s grip
Solution 2: Metal Sectional Sofa Connector Brackets
Metal sectional sofa connector brackets consist of interlocking metal plates that attach to each sofa section. Once installed, the brackets click together when the sofa pieces are pushed into place, creating a secure, long-lasting connection.

Pros:
- Durable and built to last
- Completely hidden after installation
- Screwed into the frame for a very firm hold
Cons:
- Not suitable for sofas with non-wooden frames
- Requires drilling into the sofa frame—risk of damage if misaligned
- To connect or separate sections, the sofa often needs to be lifted
- Not compatible with sofas that have curved or uneven sides
Solution 3: Alligator-Style Sectional Sofa Connectors
Alligator-style sectional sofa connectors are metal brackets with a jaw-like locking mechanism. One side is mounted to each sofa piece. As you push the pieces together, the “jaws” latch into place. These connectors offer both a strong grip and flexibility for occasional rearrangement.

Pros:
- Strong and durable metal construction
- Adjustable length to accommodate sofas with thicker fabric sides
- Spring-loaded design allows for easy release by lifting the sofa slightly
- Can be rotated 90° under the frame when not in use, keeping the sofa looking neat
- No need to lift the sofa to reconnect—just align and push into place
- Can even be used on sections with curved sides (as long as the curved sides of the two seats can align with each other.)
Cons:
- Requires at least 1 inch of clearance from the floor to the bottom frame
- Not suitable for sofas with narrow or fragile wooden frames
- Still requires drilling into the frame, which may not be ideal for users without DIY experience.
Solution 4: Buy a Modular Sofa with Built-in Connectors
Many furniture brands now offer modular sofas with built-in connectors for maximum convenience. For example, most modular sofas from Atunus Home come with built-in connectors and detailed installation instructions.
