What Causes Hip Pain at Night—and Can Your Mattress Help?
Quick Answer
Your hips may hurt when you sleep because prolonged pressure, poor sleeping posture, inadequate spinal support, an underlying joint or soft-tissue condition, or a combination of these factors is irritating the area. Side sleepers may feel concentrated pressure on the hip pressed against the mattress. A mattress that is too firm may not cushion the hip sufficiently, while one that is too soft or sagging may allow the pelvis to sink out of alignment.
Changing sleep position, improving pillow support, and choosing a mattress that balances pressure relief with stable support may help when the discomfort is sleep-surface related. However, persistent, severe, worsening, or daytime hip pain should be evaluated by a qualified healthcare professional.
Quick Facts
- Side sleeping places direct pressure on the hip closest to the mattress.
- A mattress that is too firm may create concentrated pressure around the hip and shoulder.
- A mattress that is too soft may allow the pelvis to sink and rotate the spine.
- Hip pain can also originate in the lower back, muscles, tendons, or nearby joints.
- A mattress topper may help when the mattress is supportive but feels too firm.
- A topper cannot correct deep sagging or replace a medically necessary evaluation.
Why do My Hips Hurt When I Sleep?
Hip pain at night can have several possible causes. Sometimes the discomfort comes from lying directly on the hip for hours. In other cases, the mattress does not distribute pressure effectively, or fails to keep the pelvis and spine in a neutral position.
The pain may also come from structures around the hip, rather than the hip joint itself. Muscles, tendons, bursae, nerves, and the lower back can all produce pain that is felt near the hip.
Common nighttime symptoms include:
- Aching on the outside of the hip
- Deep discomfort near the joint
- Sharp pain when rolling onto one side
- Stiffness after getting out of bed
- Pain that travels into the thigh or buttock
- Pressure that improves after changing position
- Discomfort that is worse on one mattress than another
Where the pain occurs, which position triggers it, and whether it continues during the day can provide useful clues. Those clues cannot confirm a diagnosis, but they can help you determine whether your sleep position and mattress deserve closer attention.
Common Reasons Your Hips Hurt at Night
| Possible Factor | How it May Affect the Hip | Common Clue |
| Direct side-sleeping pressure | Your body weight is concentrated over the lower hip. | Pain is strongest on the side touching the mattress. |
| Mattress is too firm | The hip cannot settle enough to distribute pressure. | The surface feels hard beneath the hip and shoulder. |
| Mattress is too soft | The pelvis sinks too deeply and may rotate the spine. | Your midsection feels trapped or unsupported. |
| Mattress sagging | A worn depression holds the pelvis below the rest of the body. | Pain is worse near a visible or measurable body impression. |
| Poor leg support | The upper leg pulls the pelvis forward during side sleeping. | Placing a pillow between the knees feels more comfortable. |
| Lower-back involvement | Irritation in the lower back may refer pain toward the hip or buttock. | Pain travels, includes tingling, or changes with spinal position. |
| Underlying medical condition | A joint, tendon, bursa, nerve, or inflammatory issue may be involved. | Pain persists during the day, worsens, or limits movement. |

This decision tree identifies possible sleep-surface factors. It is not a diagnostic tool.
How Sleeping Position Affects Hip Pain
Side Sleeping
Side sleeping places the greatest direct pressure on the hip closest to the mattress. The shoulder and hip are usually the widest points of the body, so both need enough room to settle into the comfort layers.
When the surface is too firm, the hip may remain elevated instead of settling naturally. This can concentrate pressure around the outside of the hip, and tilt the spine away from a neutral line.
When the surface is too soft, the opposite problem may occur. The pelvis can sink farther than the waist and legs, causing rotation or lateral bending through the lower back.
Side sleepers generally need:
- Enough cushioning to reduce direct hip pressure
- Enough support to prevent excessive pelvic sinking
- A pillow between the knees to reduce upper-leg pull
- A head pillow that keeps the neck aligned
- A responsive surface that makes repositioning easier

Back Sleeping
Back sleeping usually creates less direct pressure on the outside of the hip. However, pain may still occur when the mattress allows the pelvis to sink too deeply, or leaves a large unsupported space beneath the lower back.
A pillow beneath the knees may help some back sleepers reduce tension through the hips and lower back. The pillow should be supportive enough to relax the legs, without forcing the knees into an uncomfortable bend.
Stomach Sleeping
Stomach sleeping can place the pelvis in a forward-tilted position, especially when the mattress is soft. If the hips sink deeply while the chest remains higher, the lower back may become overextended.
A thinner pillow beneath the head and, in some cases, a small pillow beneath the pelvis may reduce strain. Stomach sleepers generally need a firmer and more stable surface than side sleepers of a similar body weight.
Combination Sleeping
Combination sleepers need a mattress that cushions the hips during side sleeping, but remains supportive and easy to move across. A surface with slow recovery may make it harder to change positions when pressure builds.
Natural latex has a responsive, buoyant feel that compresses under pressure and quickly regains its shape. The two-sided Natural Latex Mattress provides a Medium side and a Firm side, allowing sleepers to compare two comfort levels in the same mattress.
Can Your Mattress Cause Hip Pain?
A mattress does not cause every case of hip pain, but it can change how your body is supported and where pressure accumulates during the night.
Your mattress may be contributing when:
- Your pain is strongest on the hip touching the bed.
- The discomfort improves when you sleep elsewhere.
- You wake with hip pain that fades after moving around.
- Your mattress feels unusually hard beneath your hip.
- Your pelvis sinks into a visible depression.
- You struggle to roll over because the surface feels restrictive.
- Your hip and shoulder hurt on the same side.
- Your mattress has softened or developed impressions over time.
Mattress too Firm vs. too Soft
| Sign | Mattress May be too Firm | Mattress May be too Soft |
| Hip sensation | Sharp or concentrated pressure | Deep pulling, twisting, or sinking |
| Side-sleeping alignment | Hip remains too elevated | Pelvis drops below the waist and legs |
| Ease of movement | Usually easy, but uncomfortable | May feel trapped in the surface |
| Morning symptoms | Soreness at contact points | Stiffness through the lower back and pelvis |
| Potential adjustment | Add pressure-relieving comfort if support is intact | Use a more supportive surface or replace a worn mattress |

Why Pressure Relief Matters More Than Softness
A mattress does not have to feel extremely soft to relieve hip pressure. Softness describes the immediate surface feel, while pressure relief describes how effectively the mattress spreads body weight over a larger area.
A bed can feel plush yet allow the pelvis to sink too deeply. A somewhat firmer bed can still distribute pressure effectively when its comfort layers respond proportionally to the hip, waist, and shoulder.
Effective hip pressure relief requires the mattress to:
- Compress enough beneath the hip
- Support the waist and lower torso
- Prevent excessive pelvic rotation
- Adapt as the sleeper changes positions
- Maintain support throughout the night

The Hip Pressure Check™
Use this checklist to evaluate whether sleep position or mattress performance may be contributing to your discomfort. It is not intended to diagnose a medical condition.
| Question | What it May Suggest |
| Does the lower hip hurt most while side sleeping? | Direct pressure may be a major factor. |
| Does the pain improve quickly after changing position? | Sleep-position pressure may be involved. |
| Does the mattress feel hard beneath the hip? | The surface may not provide enough cushioning. |
| Does the pelvis sink lower than the waist? | The mattress may be too soft or worn. |
| Does placing a pillow between the knees help? | Upper-leg position may be affecting pelvic alignment. |
| Is there a visible body impression? | Mattress wear may be affecting support. |
| Does the pain occur during walking or daytime activity? | The cause may extend beyond the sleep surface. |
| Is the pain severe, worsening, or limiting movement? | A medical evaluation is appropriate. |
How Body Weight Changes Hip Pressure
Body weight affects how deeply a sleeper compresses a mattress. The same mattress may feel firm to a lighter person, balanced to an average-weight sleeper, and soft to a heavier person.
| Body-Weight Consideration | Possible Comfort Need |
| Lighter-weight side sleeper | A more pressure-relieving surface that compresses under lighter force |
| Average-weight side sleeper | Balanced cushioning with stable support through the waist and pelvis |
| Heavier side sleeper | Thicker comfort with a strong support core to prevent excessive sinking |
| Back or stomach sleeper | More resistance beneath the pelvis to preserve alignment |
Natural Latex vs. Other Mattress Materials
| Feature | Natural Latex | Memory Foam | Traditional Innerspring |
| Hip cushioning | Responsive and buoyant | Close contouring | Depends on padding thickness |
| Ease of movement | Excellent | May feel slow or restrictive | Usually good |
| Pelvic support | Resilient support without deep sink | Varies by density and thickness | Varies by coil and comfort design |
| Temperature regulation | Open-cell, breathable structure | Varies; some foam may retain heat | Airflow through the coil unit |
| Durability | Typically strong | Varies considerably | Varies by construction quality |
When can a Mattress Topper Help?
A topper may help when the mattress is still flat, stable, and supportive, but feels too firm around the hip and shoulder.
The Natural Latex Mattress Topper adds a responsive layer of natural latex, and is available in multiple thickness and firmness options.
A topper may be appropriate when:
- The mattress is supportive but lacks cushioning.
- The hip feels pressed against the surface.
- You want to modify firmness without immediately replacing the bed.
- Your mattress has no significant sagging or structural damage.
A topper is less likely to solve the problem when:
- The mattress has a deep body impression.
- The support core has softened or failed.
- The foundation is damaged or improperly supporting the bed.
- Your pain has a medical cause unrelated to pressure.
How to Reduce Hip Pressure While Sleeping
1. Place a Pillow Between Your Knees
When side sleeping, the upper leg can pull the pelvis forward and rotate the lower back. A pillow between the knees may keep the hips, knees, and ankles more evenly aligned.
2. Avoid Lying Directly on the Painful Side
Temporarily sleeping on the opposite side or on your back may reduce direct pressure. When sleeping on the opposite side, continue using a pillow between the knees to stabilize the pelvis.
3. Check Your Mattress for Sagging
Remove the bedding and inspect the surface. Look for visible depressions, uneven areas, softened edges, or a dip beneath the pelvis. Also inspect the foundation for broken slats, insufficient center support, or excessive gaps.
4. Evaluate Mattress Firmness
If the hip feels bruised or compressed, the surface may be too firm. If the pelvis feels trapped or lower than the rest of the body, the mattress may be too soft.
The two-sided Natural Latex Mattress allows sleepers to choose between a Medium side and a Firm side by turning the mattress over.
5. Change Positions Before Pressure Builds
Remaining in one position for many hours can intensify pressure. A responsive mattress makes it easier to shift positions, without fighting a deep body impression.
6. Support the Entire Sleep System
Your mattress, foundation, head pillow, knee pillow, and sleeping position work together. Replacing one component may not solve the problem if another part of the system remains unsuitable.
Common Mistakes
| Mistake | Why it May Not Help | Better Approach |
| Buying the softest mattress available | Excessive softness can allow pelvic sinking. | Balance cushioning with stable support. |
| Assuming all hip pain comes from the mattress | Hip pain can have joint, tendon, nerve, or back-related causes. | Seek evaluation when symptoms persist or worsen. |
| Adding a topper to a sagging bed | The topper may follow the existing depression. | Correct the foundation or replace the worn mattress. |
| Ignoring the upper leg | The leg may rotate the pelvis during side sleeping. | Use an appropriately sized pillow between the knees. |
| Judging firmness only by the label | Firmness scales vary between brands and materials. | Consider body weight, position, construction, and material response. |
Myth vs. Fact
| Myth | Fact |
| A soft mattress is always best for hip pain. | Too much softness may allow the pelvis to sink out of alignment. |
| A firm mattress is always more supportive. | A mattress can be firm yet fail to support the body's curves effectively. |
| Hip pain after sleeping proves the mattress is defective. | Sleep position, body condition, mattress suitability, and medical factors may all contribute. |
| A topper can repair any uncomfortable mattress. | A topper can change surface feel, but cannot restore a failed support system. |
| Only older adults experience nighttime hip pain. | Sleep-position pressure and alignment issues can affect adults of many ages. |
When Should You Seek Medical Attention?
Contact a qualified healthcare professional when hip pain:
- Persists despite changing sleep position or mattress setup
- Occurs throughout the day
- Becomes progressively worse
- Limits walking, standing, or normal movement
- Follows an injury or fall
- Is accompanied by swelling, redness, warmth, or fever
- Includes numbness, tingling, or weakness
- Prevents you from bearing weight
- Regularly wakes you despite reasonable comfort adjustments
Seek urgent medical attention for severe pain after an injury, an inability to bear weight, obvious deformity, sudden weakness, or other rapidly developing symptoms.
Bottom Line
Your hips may hurt when you sleep because of direct pressure, poor pelvic alignment, an unsuitable or worn mattress, an underlying health condition, or a combination of these factors.
Side sleepers are especially sensitive to concentrated pressure around the lower hip. A mattress that is too firm may not allow the hip to settle, while one that is too soft may let the pelvis sink and rotate the spine.
The best sleep surface is not simply the softest or firmest option. It should cushion the hip, support the waist and pelvis, preserve spinal alignment, and make changing positions easy.
A pillow between the knees, a different sleep position, a pressure-relieving topper, or a more suitable mattress may help when the discomfort is sleep-surface related. Persistent, severe, worsening, or daytime pain should be evaluated by a healthcare professional.
Frequently-Asked Questions
Why does my hip hurt only when I sleep?
Nighttime hip pain may result from prolonged pressure, sleep position, pelvic alignment, or an unsuitable mattress. Pain that regularly returns or continues during the day should be evaluated by a healthcare professional.
Why does my hip hurt when I sleep on my side?
Side sleeping places body weight directly over the lower hip. If the mattress does not distribute that pressure effectively, the outer hip may become sore or painful.
Can a mattress that is too firm cause hip pain?
A mattress that is too firm may prevent the hip from settling into the comfort layers, creating concentrated pressure around the contact point.
Can a mattress that is too soft cause hip pain?
An overly soft mattress may allow the pelvis to sink too deeply, potentially rotating the spine and placing stress around the hips and lower back.
Is a soft or firm mattress better for hip pain?
The best firmness depends on body weight, sleeping position, and mattress construction. Side sleepers often need more cushioning, while back and stomach sleepers usually need more resistance beneath the pelvis.
Can a mattress topper help with hip pain?
A topper may help when the existing mattress is supportive, but feels too firm. It cannot repair deep sagging, or treat an underlying medical condition.
Should I sleep with a pillow between my knees?
A pillow between the knees may help keep the upper leg from rotating the pelvis during side sleeping. It should support the gap, without forcing the leg unnaturally high.
Why do both hips hurt at night?
Pain on both sides may relate to repeated pressure, mattress suitability, pelvic or spinal alignment, or an underlying condition. Persistent bilateral pain deserves medical evaluation.
Can hip pain come from the lower back?
Yes. Irritation involving the lower back can sometimes be felt near the hip or buttock. Pain that travels, tingles, or includes weakness should be evaluated professionally.
Is natural latex good for side sleepers with hip pressure?
Natural latex provides responsive cushioning and resilient support. Many side sleepers appreciate its ability to compress under the hip while remaining easier to move across than deeply conforming foam.
When is nighttime hip pain serious?
Seek medical attention when pain is severe, worsening, follows an injury, prevents weight-bearing, limits movement, or occurs with swelling, redness, fever, numbness, or weakness.
