Can a Mattress Cause Restless Legs Syndrome?

Key Takeaways

• A mattress does not cause RLS, but poor mattress support can worsen symptoms.
• Too firm, too soft, or heat-trapping mattresses can increase leg discomfort and movement.
• People with RLS benefit most from plush-medium mattresses that relieve pressure and improve circulation.
• Memory foam, latex hybrids, and mattresses with cooling gel are often best for comfort and motion control.
• Improving sleep posture, nighttime routines, and sleep temperature can significantly reduce RLS restlessness.

What Is Restless Legs Syndrome?

Restless Legs Syndrome (RLS), or Willis-Ekbom Disease, is a neurological condition characterized by:

• An uncontrollable urge to move your legs
• Tingling, crawling, burning, or tightening sensations
• Symptoms that worsen at night and while resting
• Temporary relief only while moving

RLS significantly interferes with sleep, often leading to:

• Difficulty falling asleep
• Frequent night awakenings
• Daytime fatigue
• Poor concentration and mood changes

Although exact causes vary, common contributing factors include:

• Iron deficiency or low dopamine levels
• Pregnancy
• Chronic kidney conditions
• Nerve damage
• Genetic predisposition
• Certain medications

While mattresses do not create these conditions, the right (or wrong) sleep surface can dramatically influence how severe symptoms feel at night.

Mattress & RLS

No, a mattress cannot cause RLS.

However, sleep environment especially the mattress plays a major role in symptom severity.

People with RLS often experience symptoms when they are:

• Lying still
• Resting for long periods
• Trying to fall asleep

If the mattress increases pressure or restricts circulation, leg sensations can intensify, forcing the sleeper to move more often.

So the mattress doesn’t cause RLS but it can:

Effect	Result
Increase circulation issues.	More tingling and numbness.
Create pressure points.	Irritation that triggers the urge to move.
Retain heat.	Higher nerve sensitivity.
Provide poor spinal alignment.	Muscle tension that worsens discomfort.

This is why many RLS sufferers report that changing mattresses improved their sleep quality dramatically, even if the condition did not disappear.

Mattress Triggers for RLS

Below are the mattress features most likely to make RLS feel worse:

1. Mattresses That Are Too Firm

Hard surfaces increase pressure on:

• hips
• knees
• calves
• heels

This pressure can exaggerate the “crawling sensation” associated with RLS.

2. Mattresses That Are Too Soft

Overly soft beds cause the spine to sag, leading to muscle tension and poor circulation.

3. Mattresses That Hold Heat

Heat stimulates nerve activity. Many memory foams without cooling gels trap body heat, triggering discomfort.

4. Lack of Motion Isolation

When the mattress bounces or shifts easily, any small movement spreads through the bed making it harder to settle.

Right Mattress, Less Restlessness

A mattress optimized for RLS provides:

• Gentle pressure relief
• Stable support
• Motion absorption
• Cooling materials
• Balanced firmness

This reduces the urge for leg movement, allows better circulation, and helps the nervous system relax more naturally.

RLS-Friendly Mattresses

1. Memory Foam Mattresses

• Excellent body contouring
• Reduces pressure on joints
• Great motion isolation

2. Latex Mattresses

• Naturally breathable
• Supports circulation
• More buoyant, easier movement

3. Hybrid Mattresses 

• Pocketed coils support alignment.
• Comfort foams reduce pressure.
• Ideal for most sleep positions.

Mattress Comparison

Mattress Type	Pressure Relief (Leg & Hip Comfort)	Cooling & Temperature Control	Motion Isolation (Helps Reduce Sleep Disruptions)	Best For
Memory Foam	Excellent contouring helps reduce tension in legs and hips	Can retain some heat unless gel-infused or ventilated	Very good absorbs movement, ideal for restless sleepers	People who want soft, cushioned comfort and minimal motion
Latex	Responsive support with gentle pressure relief	Naturally breathable and stays cool	Good slightly more bounce than memory foam	Hot sleepers or those who switch positions often.
Hybrid	Balanced support + cushioning; reduces pressure without sinking	Better airflow due to coil system	Good pocketed coils limit motion transfer.	Most sleepers wanting comfort + support + cooling.
Innerspring	Limited pressure relief; can feel firm or uneven	Stays relatively cool due to airflow	Poor motion spreads easily across the bed	Not ideal for RLS; may worsen nighttime discomfort.

Conclusion

A mattress cannot cause Restless Legs Syndrome but the right mattress can greatly reduce discomfort, improve sleep quality, and minimize nighttime symptoms. If you have RLS, consider a medium-plush mattress with strong pressure relief, cooling, and motion isolation, such as a memory foam or hybrid model.

When your sleep surface supports your body correctly, your muscles relax, your circulation improves, and your nervous system is less likely to trigger leg restlessness helping you finally get deeper, more refreshing sleep.
