Have you started waking up sore or restless, only to notice that your mattress has a deep dip where you usually sleep?
A sagging mattress can make it hard to get the rest you need, leaving you tired, uncomfortable, and frustrated.
It’s a common issue, especially if your mattress has been with you for years. It can feel like you’re stuck tossing and turning every night.
If you’re wondering how to fix a sagging mattress, there are a few temporary tricks that can help bring back some comfort.
What Causes Your Mattress to Sag?
Over time, the constant weight on certain areas can cause materials to lose their shape and wear down.
Common causes include:
- Age of the mattress: Most mattresses only last 7–10 years before showing signs of wear.
- Foam breakdown: Memory foam and other soft layers can compress permanently after years of nightly use.
- Spring fatigue: Innerspring beds can lose support as the coils wear out or shift.
-
Improper base or support: A weak bed frame or missing slats can cause parts of your mattress to sink.
How to Identify the Sag
Sometimes sagging is obvious, but it creeps up slowly in other cases. You might notice:
- A visible dip where you usually sleep.
- Rolling toward the centre of the bed, no matter how you lie down.
- Waking up with sore hips, shoulders, or back pain.
- Feeling like your mattress doesn’t “bounce back” after you get up.
Four Practical, Temporary Fixes for a Sagging Mattress
While none of these will completely restore your mattress, here are some tips for short-term comfort:
- Add a Mattress Topper: A high-quality mattress topper adds an extra cushioning layer, making your bed feel more supportive. Look for thicker toppers made with memory foam or latex.
- Rotate or Flip Your Mattress: Rotating your mattress from head to foot can redistribute wear, and flipping it can give you a fresh surface if your mattress is double-sided. Not all modern mattresses can be flipped, so check your mattress type first.
- Use Extra Pillows for Support: Placing pillows in the sagging areas (such as under your hips or lower back) can help even the surface. This is a quick fix if you need relief right away.
-
Reinforce the Base: Sometimes the sag comes from poor support underneath. Adding slats, a bunkie board, or even a sheet of plywood between the mattress and the frame can give it more structure.
What’s a More Permanent Solution?
While it’s possible to fix a sagging mattress temporarily, once it starts to lose its structure, it won’t fully recover. A new mattress is the best way to restore comfort and proper support.
Investing in a high-quality bed means:
- Better sleep quality and less tossing and turning.
- Relief from back, hip, or shoulder pain.
- Longer durability with proper support and care.
- Peace of mind knowing your sleep setup is giving you the rest you deserve.
