Can I Stop My Sofa From Sagging?
Sofa sagging is one of the most common problems homeowners face. Over time, even the best-quality furniture begins to lose its firmness, leaving seats that feel sunken, uneven, or simply uncomfortable. The good news? Understanding why sofas sag — and what you can do about it — can help you extend the life of your furniture and know when it’s time to call in a professional.
Why Do Sofas Start to Sag?
1. Worn or Softened Foam
All foam eventually wears out. Daily use compresses the cushioning, gradually reducing its support. Even high-density foam will soften with time, especially in the most frequently used seats.
2. Tired Springs
Springs can lose tension or break completely. When this happens, you may feel a drop or hear creaking when you sit down.
3. Broken or Loose Webbing/Straps
Many modern sofas rely on woven straps or webbing to support the cushions. If these loosen or snap, the seat area will sink noticeably.
4. Frame Weakness
A damaged or cracked frame can cause one side of the sofa to dip or feel unstable. This is less common, but it’s one of the more serious structural issues.
How to Minimise Wear and Tear
- Rotate and flip cushions regularly to spread out pressure.
- Avoid sitting in the same spot every day — this prevents uneven wear.
- Keep pets off the sofa if possible, as repeated jumping compresses foam quickly.
- Use arm covers and throws to protect high-contact areas.
- Vacuum the sofa to remove debris that can grind into the foam and fabrics.
Is It the Foam, the Springs, the Straps, or the Frame?
Identifying the cause of sagging can help you understand the type of repair you may need:
- Signs it’s the foam: Cushions feel soft, flat, or squashed. When removed from the sofa, they still look misshapen. The seat platform below feels level.
- Signs it’s the springs: You feel uneven dips, hear creaking sounds, or notice that the seat platform sinks even with the cushion removed.
- Signs it’s the straps/webbing: The seat area may sag deeper in the middle, and the support feels loose or hammock-like.
- Signs it’s the frame: One side of the sofa is lower than the other, or you hear cracking when weight is applied.
When to Call a Sofa Repair Specialist
While rotating cushions and gentle maintenance can slow wear, sagging that comes from damaged springs, straps, or a weakened frame should be handled by a professional. Even foam replacement — although simple in theory — is best done by an expert who can ensure the correct density, cut, and fit.
