Why your new mattress might be causing back pain
Waking up sore after getting a new mattress?
You’re not alone... many people experience back pain after sleeping on a new mattress, even if it’s a carefully chosen high-quality bed. The good news? It doesn’t always mean you've chosen the wrong one. Like breaking in a pair of shoes, your body needs time to adjust. And if that pain persists, there are simple ways to fix it, without starting from scratch.
What you’ll learn in this article
- New mattresses can cause temporary discomfort as your body adjusts
- Most people adapt within 2–4 weeks

- Poor setup or wrong firmness can cause issues
- Simple fixes like stretching or rotating can help
- If pain persists after 30 nights, consider a return
- Mattress toppers from ViscoSoft can add comfort and support
Why does my new mattress hurt my back?
Your old mattress likely had sagging areas or uneven support that your body adapted to over time. A new mattress, especially one with better alignment and structure, can feel dramatically different.
- Changes in firmness: If you’ve switched to a firmer or softer surface, your spine may not immediately settle into it.
- Different support zones: Newer mattresses often use zoned support. This can realign pressure points and shift how your back is supported.
- Muscle memory: Your back muscles might be working overnight to adjust to a new sleep position.
How long does it take to adjust to a new mattress?
Most people need between 2–4 weeks for their body to adapt to a new sleep surface. During this adjustment period, your spine, muscles, and joints are getting used to new levels of support and pressure distribution.
4-Week Mattress Adjustment Timeline
- Week 1: Expect some stiffness or soreness, especially if the firmness level has changed significantly.
- Week 2: Discomfort may persist but should gradually decrease. Continue sleeping on the mattress nightly.
- Week 3: Your body begins adapting more fully. If pain is still strong or worsening, take note.
- Week 4: Most sleepers feel better by now. If not, it may be time to reassess your setup or consider a topper.
What’s normal during the adjustment period and what’s not
| Normal | Not Normal |
|---|---|
| Mild back or neck soreness | Sharp, persistent pain or numbness |
| Improving comfort over time | No improvement after 30 nights |
| Soreness in new pressure zones | Worsening pain every night |
5 common mistakes that can lead to back pain after a new mattress
-
Choosing the wrong firmness level: Your spine needs proper alignment during sleep. A too-firm mattress can create pressure points in the lower back or hips. A too-soft mattress may let your body sink too much, throwing off your posture.
👉 If you’re unsure, a medium-firm mattress with a plush topper often hits the sweet spot for many sleepers. -
Not accounting for your sleep position: A mattress that feels great for a back sleeper might not work for someone who sleeps on their side or stomach. Stomach sleepers often need firmer support under the hips. Side sleepers benefit from more cushioning at the shoulders and hips.
👉 Toppers can help fine-tune your comfort based on your sleep style. - Using an improper base or frame: A weak or unsupportive base compromises your mattress’s performance and durability.
- Not rotating the mattress: Some mattresses need rotating to maintain even wear. This helps reduce pressure points as the mattress settles.
- Not giving it enough time: Many people expect instant comfort and give up too soon. Give yourself at least 30 days to truly assess comfort.
How to ease back pain from a new mattress
Before assuming you made the wrong choice, try the following step-by-step approach to minimize discomfort:
- Before you buy: Choose the right firmness and mattress type for your sleep style and body weight. Don’t skip testing options or reading return policies.
- Set it up right from day one: Make sure your bed base is sturdy, let the mattress fully expand, and use a breathable protector to avoid heat buildup.
- Be patient: Your body needs time to adjust. Stick with it for at least 30 days.
- Support your body: Rotate the mattress weekly during the first month. Do gentle stretches morning and night to keep muscles loose.
- Reassess after 30 nights: Still sore? Try adding a plush mattress topper. If there’s no improvement, consider an exchange or return.
When should you consider returning or replacing the mattress?
Most discomfort fades with time, but not always. Watch for these signs that your mattress may simply not be a good fit:
- Back pain that worsens or never improves
- Feeling like you’re sleeping on a board or sinking too deeply
- Numbness or tingling in your limbs
- No improvement after 30 nights
Many mattresses come with a trial period. Before returning, try soft fixes like a topper, firmer base, or rotating the mattress. Need help deciding? Reach out to our sleep specialists - we're here to guide you.
