Is Your Mattress Sagging? Here’s When to Replace It
Your baby’s mattress may look fine at a glance, but over time, it can lose the support and structure it once had—especially with daily use. One of the most common signs it’s time for a replacement? Sagging.
At iStyle Mode, we know how crucial a safe, supportive sleep surface is for your little one’s comfort and development. So if your cot bed mattress has started to dip or feel uneven, it might be time to take a closer look.
What Does Mattress Sagging Look Like?
Sagging can be subtle or obvious. You might notice:
-
A visible dip where your child lies
-
Uneven surface when you press down
-
Reduced firmness or bounce
-
Your baby rolling into the same spot each night
While some wear is normal, sagging compromises comfort and safety.
Why a Sagging Mattress Is a Problem
1. Poor Spinal Support Babies and toddlers need firm support to help their growing bones and developing posture. A sagging mattress can throw off their alignment, causing discomfort or long-term posture issues.
2. Safety Risks Soft, uneven surfaces increase the risk of your baby rolling into unsafe sleep positions, especially for infants who can’t reposition themselves easily.
3. Sleep Disruption Imagine trying to sleep on a mattress that sags every time you move. If your child is waking up more often or fussing at bedtime, their mattress might be the issue.
4. Allergen Build-Up Older mattresses, especially ones that have sagged or absorbed moisture, can trap dust mites, allergens, and bacteria—no thanks!
When to Replace a Cot Bed Mattress
Here are clear signs it’s time to swap it out:
✅ There are visible dips or uneven areas
✅ The mattress feels softer or lumpy in some spots
✅ It’s been used daily for 3–5 years
✅ You notice an odour, stains, or signs of mould
✅ Your child isn’t sleeping as soundly or comfortably
Even high-quality mattresses will eventually wear out. For babies and toddlers, a supportive, breathable sleep surface is non-negotiable.
