Advice
Getting a new mattress should feel exciting, but it can be frustrating when it doesn’t feel perfect right away. Maybe it feels too firm, too soft, or you wake up sore and wonder if you made the wrong choice. The good news? Your mattress and body may simply need time to adjust. Before considering an exchange, let’s look at what’s normal, what’s not, and what you can do to improve your comfort.
Why Your New Mattress Feels Different at Home
One of the most common things customers say is that their new mattress does not feel like the one they tried in the showroom.
This can happen for a few reasons:
- The showroom model has already been broken in by other shoppers.
- Your new mattress contains fresh comfort materials that may feel slightly firmer or tighter when you first begin using it. Your old mattress may have years of body impressions and softened materials. Your sheets, mattress protector, pillow, foundation, or room temperature may also change how the mattress feels.
- Your body may need time to adjust to better support. A new mattress could feel different at first, especially if your previous mattress had lost support over time. Your body may simply need a little time to adjust to the new level of comfort and support.It’s like breaking in a new pair of shoes; the support may be better for you, but your body can still need a little time to adjust.
How Long Does It Take to Adjust to a New Mattress?
Most customers should allow at least a minimum of 7 to 30 nights to adjust to a new mattress. If you’re switching from a very old mattress or a different type, it may take up to 30–60 nights for your body to fully adapt.
Mattress type and materials can also impact break-in time. Memory foam, hybrids, high-density foams, and heavier coil systems may feel firmer at first, then gradually soften and adjust with regular use.
Your body is adjusting, too. During this period, you may notice:
- Mild soreness when waking up
- Lower back or shoulder discomfort
- Pressure in the hips or shoulders
- Stiffness in the morning
- A different feeling of spinal alignment
- More support than you are used to
Some initial discomfort can be normal and should improve over time as your body adjusts. However, if discomfort worsens, disrupts your sleep, causes numbness, or doesn’t improve after the adjustment period, it may indicate that the mattress isn’t the right fit.
Why a New Mattress May Feel Too Firm
A mattress feeling firmer than expected is one of the most common concerns after delivery. In many cases, this is simply because the new materials have not fully broken in yet.
The comfort layers may simply need time to break in and relax. Our showroom mattresses often feel softer because they have already been tested by customers, while your new mattress is still fresh and unused.
Your bedding can also make a surprising difference. Tight sheets or a snug mattress protector can create a “drum effect,” making the mattress feel firmer than it really is. Some protectors can also make the bed sleep warmer, which may change how certain foams feel.
Room temperature can also affect how your mattress feels. Foam materials tend to feel firmer in cooler rooms and softer or more flexible in warmer temperatures.
What Helps When a New Mattress Feels Too Firm
Try these steps before assuming the mattress is wrong:
- Sleep on it consistently for the full adjustment period.
- Rotate the mattress every 2 to 3 weeks during the first few months.
- Gently crawl or roll across the mattress to help condition the comfort layers.
- Check that your fitted sheet is not too tight.
- Check that your mattress protector is not pulling the surface too tight.
- Make sure your pillow height still works with your new mattress.
- For foam mattresses, slightly warming the room may help the foam feel less stiff.
- Avoid jumping on the mattress. Gentle movement can help, but jumping can damage the bed or create unnecessary wear.
A helpful way to think about this is to “condition” the mattress instead of “break it in.” Regular use, rotation, and time usually do more than quick fixes.
Why a New Mattress May Feel Too Soft
When a customer says their mattress feels too soft, the mattress is not always the problem. In many cases, the issue is the support system underneath it.
A mattress can only perform as well as the support system underneath it. If the foundation, frame, platform, or adjustable base is weak, uneven, bowed, or missing proper center support, the mattress may feel softer or less supportive than intended.
Common setup problems include:
- Old box springs
- Weak or broken foundations
- Slats spaced too far apart
- Bowed slats
- Missing center support
- No center leg touching the floor
- Roll slats under a foam mattress
- A foundation set up upside down
- A frame or foundation that is not level
- Reusing an old support system with a new mattress
The wrong foundation can make a mattress feel uneven, unstable, too soft, or unsupported. It can also cause the mattress to sag prematurely and may affect warranty coverage.
The Quickest Test: Put the Mattress on the Floor
If your mattress feels too soft, uneven, or unsupported, try placing it directly on the floor for a night or two.
If the mattress feels better when placed directly on the floor, the issue is likely related to the foundation, frame, slats, or overall support system. If it feels the same on the floor, the concern may instead be related to comfort, alignment, or the mattress itself.
This simple floor test is one of the fastest ways to separate a mattress issue from a support issue.
Your Pillow Can Change How Your Mattress Feels
Your pillow plays a bigger role than many people realize. In fact, your pillow provides about 30% of your overall support.
When you get a new mattress, your old pillow may no longer be the right fit. A mattress that changes how deeply your shoulders or hips sink can also change how much pillow height you need.
A pillow that is too high or too low can throw off your alignment and make the mattress feel wrong, even if the mattress is doing its job.
General Pillow Tips
- Side sleepers: Medium to tall pillow
- Back sleepers: Low to medium pillow
- Stomach sleepers: Low pillow
- Combination sleepers: Medium pillow
Pillow fit can also depend on shoulder width and mattress softness. For example, side sleepers with broader shoulders often need a taller pillow, while softer mattresses may require less pillow height since the shoulders sink in more.
If your new mattress feels uncomfortable, do not forget to check your pillow before assuming the mattress is the issue.
Common Mattress Fit Issues by Sleep Position
Different sleep positions usually create different complaints during the adjustment period.
Side Sleepers
Side sleepers often notice shoulder pressure, hip pressure, or numbness if the mattress does not provide enough pressure relief. A mattress that is too firm may prevent the shoulder and hip from sinking in enough.
Back Sleepers
Back sleepers often notice lower back discomfort when the mattress does not support the natural curve of the spine. They may describe the bed as unsupportive, too soft, or not quite right through the lumbar area.
Stomach Sleepers
Stomach sleepers often struggle when a mattress is too soft. If the midsection sinks too much, it can create strain through the upper, middle, or lower back.
Combination Sleepers
Combination sleepers may need a balance of comfort and support. If the mattress is too soft, it may feel hard to move around. If it is too firm, it may create pressure when sleeping on the side.
When a New Mattress Feeling “Off” Is Normal
Some discomfort can be part of the adjustment period, especially if:
- The discomfort is mild.
- It improves gradually.
- You recently switched mattress types.
- You replaced an old sagging mattress.
- Your body is adjusting to better alignment.
- The mattress feels slightly different, but not uneven or defective.
In these cases, time and small adjustments often help.
Try checking your sheets, protector, pillow, foundation, room temperature, and rotation schedule before deciding the mattress is not right.
When It May Actually Be a Problem
A mattress concern may be more serious if you notice:
- Visible sagging
- Dips or valleys
- Lumps or voids
- One side measuring differently than the other
- One section feeling much softer or firmer than the rest
- Rolling toward the middle or edge
- Pain that gets worse instead of better
- Numbness or severe pressure points
- Sleep being interrupted night after night
- The mattress feeling unsupported even on the floor
If you believe your mattress may be defective, please contact the mattress manufacturer directly to begin a warranty claim. If you purchased your mattress from us, you can start your warranty claim at www.mymattresswarranty.com
If the issue is comfort-related and not a defect, contact your local BedMart Expert Sleep Consultant to review your options and next steps.
What Solves Most New Mattress Complaints?
In many cases, the solution may be simpler than replacing the mattress entirely. Based on experience, approximately 80% to 95% of new mattress concerns can often be improved through adjustments or troubleshooting, though every situation is unique.
The most helpful fixes are usually:
- Give the mattress enough time to adjust.
- Rotate it regularly.
- Check the foundation and support system.
- Try the floor test.
- Check tight sheets or mattress protectors.
- Recheck pillow height.
- Confirm the customer received the correct mattress.
The biggest mistake is exchanging too soon before ruling out these common issues. If the foundation, pillow, bedding, or adjustment period is the real problem, the next mattress may not solve the issue either.

Final Takeaway
If your new mattress does not feel right immediately, take a breath. It does not always mean you made the wrong choice.
A new mattress may need time to condition. Your body may need time to adjust. Your sheets, protector, pillow, or foundation may also be changing the way the mattress feels.
Start with the simple checks first. Give your mattress a fair adjustment period, make sure it is properly supported, and watch for signs of improvement.
Still not sure if your mattress is the right fit?Our BedMart Expert Sleep Consultants can help you troubleshoot your setup and determine the best next step.
It is normal for a new mattress to feel different at first. Your mattress may need time to condition, your body may need time to adjust, or your sheets, mattress protector, pillow, or foundation may be affecting the feel. A new mattress can also feel different from the showroom model because the showroom mattress has already been broken in through regular use.
Most people should give a new mattress at least 30 nights to adjust. If you are switching from an older mattress or changing mattress types, it may take up to 60 nights for your body to fully adapt.
A new mattress may feel firmer because its comfort materials have not yet been conditioned through regular use. Tight sheets or a mattress protector can also pull across the surface and make the mattress feel firmer. Room temperature may also affect how some foam materials feel.
Give the mattress time to adjust and use it consistently. You can also check that your sheets and mattress protector are not too tight, rotate the mattress as recommended, and make sure your pillow is still the right height. Gentle movement across the mattress can help condition the comfort layers.
If your new mattress feels too soft or unsupported, check the foundation, frame, slats, or other support system underneath it. Weak or uneven support, missing center support, or an old foundation can change how the mattress feels and may cause it to feel softer than expected.
Yes. Your mattress depends on the support system underneath it. A weak, uneven, bowed, or improperly supported foundation or frame can make a mattress feel softer, uneven, or less supportive than intended.
Yes. A new mattress can change how deeply your shoulders and hips sink, which can change the pillow height you need. If your pillow is too high or too low, it can affect your alignment and make the entire sleep setup feel uncomfortable.
Mild soreness or stiffness can happen while your body adjusts to a new mattress, especially if you switched from an older or significantly different mattress. However, discomfort that gets worse, causes numbness, or does not improve over time may be a sign that the mattress is not the right fit.
Showroom mattresses have already been used and conditioned by customers, while your new mattress is fresh and unused. Your old mattress, bedding, pillow, room temperature, and support system can also make your new mattress feel different at home.
A temporary floor test can help determine whether your support system is affecting the feel of your mattress. If the mattress feels better on the floor, the foundation, frame, slats, or other support components may need to be checked.
Before considering an exchange, make sure you have allowed enough time for your body and mattress to adjust and have checked your foundation, bedding, pillow, and overall setup. If the mattress continues to feel uncomfortable or does not seem like the right fit after troubleshooting, contact your local BedMart Expert Sleep Consultant to discuss your options.
Visible sagging, dips, valleys, lumps, uneven areas, or a section of the mattress that feels noticeably different from the rest may indicate a potential defect. If you believe your mattress may be defective, you can begin a warranty claim through the appropriate warranty process.
