Best Mattress for Sciatica in Canada: A Practical Guide to Sleeping With Less Pain
Quick Answer: What Mattress Is Best for Sciatica?
A medium-firm mattress (around 6 to 7 on a 10-point firmness scale) tends to work best for most people with sciatica. Look for a mattress with good pressure relief at the hips and shoulders, enough support to keep your spine aligned, and responsive materials that let you change positions easily. Memory foam and hybrid mattresses are popular choices. Side sleepers with sciatica often do well with slightly softer options, while back sleepers usually prefer firmer support.
What Is Sciatica, and Why Does Your Mattress Matter?
Sciatica is pain that radiates along the sciatic nerve, running from your lower back through your hips and down each leg. It is usually caused by a herniated disc, bone spur, or spinal narrowing that puts pressure on the nerve. The pain can range from a dull ache to a sharp, burning sensation that makes it difficult to sit, stand, or sleep.
Your mattress matters because you spend roughly a third of your life on it. A mattress that is too soft lets your hips sink too far, curving your spine and compressing the nerve. One that is too firm pushes against your hips and creates pressure points. Either way, you wake up worse than when you went to bed.
The Science Behind Sleep and Sciatica
During sleep, your intervertebral discs rehydrate and decompress. A properly supportive mattress maintains neutral spinal alignment, allowing the discs in your lumbar region to recover. Research published in The Lancet found that medium-firm mattresses reduced back pain and disability more effectively than firm mattresses. For sciatica specifically, the goal is to minimize pressure on the piriformis muscle and sciatic nerve root while maintaining natural spinal curvature.
What to Look for in a Mattress When You Have Sciatica
Shopping for a mattress when you are dealing with nerve pain can feel overwhelming. Here is what actually matters, based on what we hear from customers and what sleep research supports.
Firmness Level
Medium-firm is the sweet spot for most people with sciatica. On a scale of 1 to 10 (where 10 is a rock), aim for a 6 to 7. This gives your hips enough cushioning to relieve pressure while keeping your spine properly aligned.
That said, your body weight plays a role. If you weigh under 130 pounds, you might prefer a 5 to 6. If you weigh over 230 pounds, a 7 to 8 may offer better support. The right firmness is the one that keeps your spine in a straight line from neck to tailbone.
Pressure Relief
This is arguably the most important factor. Your mattress needs to cushion the areas where your body is widest, mainly hips and shoulders, without letting them sink too deep. Memory foam and latex excel at pressure relief because they contour around your body rather than pushing back against it.
Spinal Alignment
When you lie on your side, your spine should form a straight horizontal line. When on your back, it should maintain its natural S-curve. A mattress that sags in the middle or does not support the lumbar area will worsen sciatica over time.
Responsiveness
People with sciatica tend to shift positions frequently during the night looking for a comfortable spot. A mattress that responds quickly to movement, such as a hybrid or latex, makes it easier to reposition without feeling stuck.
Mattress Type Comparison for Sciatica
- Memory Foam: Excellent pressure relief, good spinal alignment, slower responsiveness. Great for side sleepers with sciatica.
- Hybrid (Coils + Foam): Good pressure relief with better airflow and responsiveness. Works well for combination sleepers who change positions often.
- Latex: Natural pressure relief with quick responsiveness. A good option if you want contouring without the "stuck" feeling of memory foam.
- Innerspring: Good support but less pressure relief. May need a quality mattress topper for adequate cushioning.
Best Sleep Positions for Sciatica
Your sleep position matters just as much as your mattress. Here is what tends to help.
Side Sleeping (With a Pillow Between Your Knees)
This is often the most comfortable position for sciatica. Placing a pillow between your knees keeps your hips level and reduces the twist on your lower spine. A medium to medium-firm mattress works well here because it allows your shoulder and hip to sink in slightly while supporting your waist.
Back Sleeping (With a Pillow Under Your Knees)
Sleeping on your back with a pillow under your knees tilts your pelvis and takes pressure off the sciatic nerve. A medium-firm to firm mattress provides the flat, supportive surface this position needs.
Stomach Sleeping
We generally do not recommend stomach sleeping for sciatica. It forces your spine into extension and can increase nerve compression. If you simply cannot sleep any other way, a firmer mattress and a thin pillow (or no pillow) under your head can minimize the strain.
Comfort Tip: The Tennis Ball Trick
If you tend to roll onto your stomach during the night, try placing a tennis ball in a sock and pinning it to the front of your pyjama top. It sounds odd, but many customers tell us it works. The gentle discomfort reminds your body to stay on your side or back where your spine is better supported.
How We Help at Mattress Miracle
We have been helping Brantford families find the right mattress since 1987. When someone comes in with sciatica, we do not just point them toward the most expensive option. We ask about their sleep position, pain patterns, body weight, and budget. Then we let them try different mattresses right in our showroom.
In our experience, there is no single "best mattress for sciatica" that works for everyone. What works is finding the right combination of support and pressure relief for your specific body and pain pattern. That is something you can only really figure out by lying on a mattress for more than two minutes.

Other Things That Help Sciatica at Night
A good mattress is important, but it is not the only thing that can improve your sleep with sciatica. Here are a few other strategies that many people find helpful.
- Adjustable bed base: Elevating your upper body slightly and raising your knees can take significant pressure off the sciatic nerve. Many of the mattresses we carry work well with adjustable bases.
- Proper pillow support: A pillow between or under your knees, depending on your sleep position, helps maintain alignment.
- Gentle stretching before bed: A few minutes of piriformis stretches and gentle hamstring stretches can ease tension before you lie down.
- Heat or cold therapy: Some people find that a heating pad on their lower back for 15 to 20 minutes before bed helps relax the muscles around the nerve.
When to Replace Your Mattress
If your sciatica is worse in the morning than at night, your mattress may be part of the problem. Most mattresses last 7 to 10 years, but if yours is sagging, lumpy, or simply not providing the support it once did, it could be making your pain worse.
A quick test: lie on your mattress on your back. If you can slide your hand easily between your lower back and the mattress, it may be too firm. If your hips sink noticeably and you feel like you are in a hammock, it is too soft. Either way, it might be time for a change.
Frequently Asked Questions
Is a firm or soft mattress better for sciatica?
Neither extreme is ideal. A medium-firm mattress (about 6 to 7 on a 10-point scale) generally works best for sciatica because it balances pressure relief with spinal support. Too soft and your hips sink, compressing the nerve. Too firm and your pressure points get aggravated.
Can a bad mattress cause sciatica?
A mattress alone does not cause sciatica, but a poor mattress can worsen existing sciatic nerve irritation. An unsupportive mattress can misalign your spine during sleep, increasing pressure on the discs and nerves in your lower back, which may aggravate or prolong sciatica symptoms.
Is memory foam good for sciatica?
Memory foam can be very helpful for sciatica because it contours to your body and relieves pressure at key points like the hips and lower back. Look for a medium-firm memory foam or a hybrid that combines foam comfort layers with supportive coils for the best combination of pressure relief and support.
What sleep position is best for sciatica?
Side sleeping with a pillow between your knees is often the most comfortable position. It keeps your hips aligned and reduces pressure on the sciatic nerve. Back sleeping with a pillow under your knees is also a good option. Stomach sleeping tends to make sciatica worse.
How long does it take to adjust to a new mattress with sciatica?
Most people need 2 to 4 weeks to adjust to a new mattress. Your body has adapted to your old sleeping surface, even if it was not ideal. Give yourself at least 30 days before deciding whether a new mattress is helping your sciatica. Many mattress brands and retailers offer trial periods for this reason.
