Investing in a high-quality mattress from top UK brands is an exciting step toward better sleep. However, that excitement often turns to frustration when your new mattress too firm, leaving you feeling like you’re sleeping on a concrete slab.
If you are waking up with aching joints, don’t panic. This is a common issue for sleepers in the UK, especially with our unique climate and preference for traditional craftsmanship. In this guide, we will explore why your bed feels like a “rock” and provide expert solutions to transform your sleep.
1. The “Breaking-In” Period: Why Your Mattress Starts Firm
Just like a new pair of leather brogues, a mattress needs a “breaking-in” period. When a mattress is manufactured, the foam cells and steel coils are at their peak tension.
- The 30-Night Rule: Most UK manufacturers, including Hippo and Silentnight, recommend at least 30 nights to allow the materials to soften and your body to adjust.
- Temperature Sensitivity: If you have a memory foam model, you might find your memory foam mattress too hard in cold room conditions. In the UK’s chilly winters, foam stays rigid. It requires body heat and a warmer ambient temperature to become pliable.
Expert Insight: Many competitors overlook the “slat gap” issue. If your bed frame slats are more than 75mm apart, your mattress may sag in some areas and feel unnaturally rigid in others. Always check your base first!

2. 5 Pro Tips to Soften Your Bed for Free
Before spending more money, try these expert-approved methods to fix a new mattress too firm:
- Walk the Plank: Spend 10–15 minutes a day gently walking on your mattress. This helps the “cell structure” of the foam to open up, and the new mattress too firm springs to lose their initial stiffness.
- Warm Up the Room: Ensure your bedroom is around 18-19°C. This is the “sweet spot” for memory foam to react to your body weight.
- Rotate, Don’t Flip: Most modern mattresses are one-sided. Rotating it 180 degrees every week for the first month ensures even wear.
- The “Pillow Factor”: Sometimes the mattress isn’t the problem. If your mattress is firm, you need a slightly thinner pillow to keep your spine aligned.
- Check the Protector: A tight, non-stretchy mattress protector can create a “drum effect,” making the surface feel harder than it is. Try a quilted cotton protector instead.
3. The “Quick Fix”: Top Mattress Toppers to Rescue Your Sleep
If you’ve tried the tips above and are still breaking in a new mattress hip pain is ruining your nights, a mattress topper is your best investment. It adds an immediate “comfort layer” without the hassle of returning a heavy mattress.

4. Why We Recommend These Specific Fixes
When searching for the best mattress topper for firm bed back pain, you need to match the topper to your specific mattress type:
- For Pocket Spring Mattresses: Use the My Nature Airflow Mattress Topper. Traditional springs provide great support but can feel “bouncy” or hard on the surface. This topper adds a breathable buffer.
- For Memory Foam Mattresses: Use the TheraPur ActiGel® Cool Mattress Topper. It solves the “too hard” issue while ensuring you don’t overheat—a common complaint with standard foam.
- How to soften a firm pocket sprung mattress: If you want a significant change in “feel,” the Dream Team Ultimate Washable Mattress Topper adds 5cm of plushness, effectively acting as a “pillow-top” layer.

5. Should You Return It? (UK Consumer Rights)
You might be wondering, “Can you return a mattress if it’s too firm?” In the UK, the answer depends on where you bought it:
- Comfort Guarantees: Dreams offers a 100-night “Comfort Exchange,” and Bensons for Beds typically offers a 40-night guarantee.
- Condition Matters: You must use a mattress protector. If the mattress is stained, the guarantee is void.
- Statutory Rights: Under the Consumer Rights Act 2015, you can’t usually return a mattress just because it’s uncomfortable unless it was misdescribed or faulty.
Final Verdict: Is Your Bed a “Keeper”?
A new mattress too firm is rarely a permanent problem. By using the “walking” technique and adjusting your room temperature, most sleepers find comfort within 4 weeks. However, if you are a side sleeper suffering from shoulder or hip pain, adding a high-quality topper from Dreams or Bensons for Beds is the most cost-effective way to achieve deep, restorative sleep without the stress of a full return.
