Quick Answer
The best mattress for hip replacement recovery in Canada is a medium-firm hybrid with targeted hip pressure relief, strong edge support, and adjustable base compatibility. Canada performs over 60,000 hip replacements annually (CIHI), and the mattress you recover on significantly affects your comfort, safety, and healing. After hip replacement, your mattress must balance two needs: firm enough to support the operated hip and prevent excessive sinking (which can violate hip precautions), yet soft enough at the hip zone to relieve pressure on the surgical site. Strong edge support is critical because getting in and out of bed is the most challenging daily activity during recovery. An adjustable base allows positioning changes without straining the new joint.
Posterior vs Anterior Hip Replacement: How Your Approach Affects Sleep
The surgical approach your surgeon uses determines which movements are restricted during recovery, and this directly affects which sleep positions are safe and what your mattress needs to accommodate.
| Factor | Posterior Approach | Anterior Approach |
|---|---|---|
| Incision location | Back/side of the hip | Front of the hip |
| Main precautions | No hip flexion past 90 degrees; no crossing legs; no internal rotation | Fewer precautions; no extreme hip extension or external rotation |
| Sleep position restrictions | Back sleeping with pillow between knees for 6 weeks; side sleeping on non-operated side only (with pillow between knees) | Less restrictive; back sleeping recommended but side sleeping generally allowed earlier |
| Mattress implication | Must prevent the hip from sinking past 90 degrees of flexion; firmer surface needed initially; very strong edge support for log-roll transfers | Medium-firm is usually sufficient from the start; still need strong edge support for safe transfers |
| Precaution duration | Typically 6 to 12 weeks | Typically 2 to 6 weeks (some surgeons have minimal precautions) |

The Right Firmness After Hip Replacement
Most orthopaedic surgeons recommend a medium-firm to firm mattress after hip replacement. The reasoning is straightforward: a too-soft mattress allows the hip to sink deeply, which can cause the hip joint to flex past 90 degrees (violating the most common posterior approach precaution) and makes it very difficult to get out of bed without straining the new joint.
| Sleep Position | Firmness | Why |
|---|---|---|
| Back sleeper (primary recovery position) | Medium-firm (6 to 7) | Distributes weight evenly; keeps the hip in a neutral position; prevents excessive hip flexion |
| Side sleeper (non-operated side, when cleared) | Medium (5 to 6) | Hip and shoulder need to sink enough to maintain spinal alignment; always use a pillow between the knees |
| Higher body weight (over 100 kg) | Firm (7 to 8) | Heavier individuals sink deeper; a firmer surface prevents the hip from exceeding 90 degrees of flexion |
| Long-term (after precautions lifted) | Medium-firm (6 to 7) | The prosthetic joint benefits from consistent support without excessive pressure on the hip bone |
The 90-Degree Rule and Your Mattress
After a posterior approach hip replacement, you must not bend your operated hip past 90 degrees. When lying on a very soft mattress, the hip can sink deeply enough to exceed this angle, especially in a side-lying position. Test your mattress by lying on your side: if your hip sinks so deeply that your knee drops below your hip level, the mattress is too soft for safe recovery. A medium-firm surface keeps the hip at a safe angle while still providing enough cushioning for comfort.
Essential Mattress Features for Hip Replacement Recovery
| Feature | Why It Matters After Hip Replacement | What to Look For |
|---|---|---|
| Edge support | You will sit on the mattress edge to get in and out of bed. Weak edges cause the hip to drop below the safe angle and increase fall risk during transfers | Reinforced perimeter coils or high-density foam edge; sit on the edge before buying and check that your hips stay level with or above your knees |
| Hip-zone pressure relief | The surgical site is tender and the hip bone is sensitive after surgery. Excessive pressure at the hip causes pain and disrupts sleep | Zoned comfort layers with softer foam at the hip zone or responsive latex that conforms without creating pressure points |
| Responsive surface | You must reposition without twisting the operated hip. A responsive surface (springs back quickly) makes log-rolling and position changes easier | Latex or pocketed coils; avoid dense, slow-recovery memory foam |
| Proper bed height | Too low forces the hip past 90 degrees when sitting; too high creates a fall risk when stepping down | Total bed height (mattress + frame/base) should place your hips at or above knee level when sitting on the edge |
| Adjustable base compatibility | Head elevation reduces strain when sitting up; knee elevation takes pressure off the hip; some bases have power lift to assist getting out of bed | Flexible mattress that bends smoothly; most hybrids and all-foam mattresses are compatible |
| Motion isolation | Partner movement causing sudden mattress motion can jolt the operated hip during sleep | Pocketed coils or foam layers; avoid connected coil systems |

Safe Sleep Positions After Hip Replacement
Always follow your surgeon's specific instructions, as these vary by surgical approach and individual case. These are general guidelines for the most common scenarios.
Posterior Approach Sleep Positions
Back sleeping is the safest position for the first 6 weeks. Place a pillow between your knees to prevent the operated leg from crossing the midline (which violates hip precautions). Side sleeping on the non-operated side is usually allowed with a pillow between the knees to keep the legs separated. Sleeping on the operated side is typically restricted for 4 to 6 weeks. Stomach sleeping is generally prohibited during recovery because it forces hip extension and rotation. Your mattress must be firm enough to prevent the hip from sinking past 90 degrees in any of these positions.
Anterior approach: These patients typically have fewer sleep restrictions. Back sleeping is still recommended initially, but side sleeping may be allowed sooner. Your surgeon will provide specific guidance based on your procedure.
Pillow placement is essential:
- Between the knees: Keeps the operated leg from crossing the midline and maintains hip alignment (required for posterior approach)
- Under the knees (back sleeping): Reduces hip flexion and takes pressure off the surgical site
- Behind the back: Prevents rolling onto the operated side during sleep
Getting In and Out of Bed Safely
Your mattress and bed setup must support safe transfers, which are the highest-risk daily activity after hip replacement.
Getting into bed:
- Back up to the bed until you feel the mattress edge behind your legs
- Reach back with both hands to the mattress surface for stability
- Slowly lower yourself to a seated position on the mattress edge (the edge must not collapse)
- Keep the operated leg extended slightly forward (avoid bending the hip past 90 degrees)
- Scoot back, then swing your legs onto the bed while turning your body as a unit (log roll)
Getting out of bed:
- Log roll to the edge of the bed (move shoulders and hips together, without twisting)
- Push yourself up to a seated position using your arms (not your hip or abdominal muscles)
- Slide to the edge with both feet on the floor (the mattress edge must support your seated weight)
- Push up to standing using your arms and the non-operated leg; the operated leg stays slightly forward
The Bed Height Check
Before surgery, sit on the edge of your bed and check that your hips are at the same level as or slightly higher than your knees. If your hips drop below your knees, your hip is flexing past 90 degrees every time you sit on the bed, which violates posterior approach precautions. Solutions: add bed risers (available at Canadian Tire or Amazon.ca for $20 to $40), use a thicker mattress, or switch to a taller foundation. An adjustable base also adds height. The ideal total bed height for most hip replacement patients is 55 to 65 cm from the floor.
Hip Precautions and Your Mattress
| Precaution (Posterior Approach) | Mattress Implication | Solution |
|---|---|---|
| No hip flexion past 90 degrees | A soft mattress can allow the hip to sink deeply enough to exceed 90 degrees, especially when lying on your side | Medium-firm to firm mattress; avoid excessive sinking at the hip zone |
| No crossing the midline | During sleep, the operated leg can drift across the body's midline, risking dislocation | Pillow between the knees; a body pillow prevents the leg from crossing during sleep |
| No internal rotation | Twisting movements during sleep can internally rotate the operated hip | Responsive mattress surface for easy, controlled log-roll repositioning; pillow behind back to prevent rolling |
| Sit with hips above knees | When sitting on the mattress edge, a low bed or soft edge lets hips drop below knee level | Strong edge support; bed height at or above knee level; bed risers if needed |
Recovery Timeline: When Sleep Improves
| Week | What to Expect | Sleep Tips |
|---|---|---|
| Week 1 to 2 | Most painful period; sleep is frequently disrupted by pain and medication schedules; some patients use a recliner | Use adjustable base or pillows for elevated positioning; take pain medication 30 minutes before bed; ice the hip before sleep |
| Week 3 to 6 | Pain decreasing; you are spending more time in bed and less in a recliner; side sleeping may be cleared | Begin using the mattress as your primary sleep surface if not already; maintain pillow between knees; edge support becomes more important as you transfer independently |
| Week 6 to 12 | Precautions may be lifted; most patients can try different sleep positions; sleep quality improving | Gradually try sleeping on your side (with pillow between knees initially); you may be able to use a slightly softer mattress firmness |
| Month 3 to 6 | Most patients sleeping comfortably; residual hip soreness may linger but does not significantly disrupt sleep | Focus on long-term comfort; if your mattress was chosen primarily for recovery firmness, you may want to add a comfort topper or flip to the softer side (if flippable) |

FAQ
Can I sleep on my side after hip replacement?
For posterior approach: you can typically sleep on the non-operated side after 2 to 4 weeks, always with a pillow between your knees. Sleeping on the operated side is usually restricted for 4 to 6 weeks. For anterior approach: side sleeping may be allowed sooner. Always follow your surgeon's specific instructions, as precaution timelines vary.
Should I get a new mattress before hip replacement surgery?
If your current mattress is soft, sagging, has weak edges, or is too low, yes. Replace it 1 to 2 weeks before surgery so it is set up and broken in when you come home. A mattress with strong edge support and medium-firm feel is essential for safe bed transfers during recovery. If your current mattress is relatively firm with good edge support and at the right height, it may work fine.
Do I need an adjustable base after hip replacement?
An adjustable base is strongly recommended. It allows head elevation (helps with getting up without straining the hip), knee elevation (reduces hip pressure), and some models have power-lift features that help you transition from lying to sitting. If an adjustable base is not feasible, wedge pillows under the head and knees can provide some of the same benefits.
How high should my bed be after hip replacement?
Your hips should be at the same level as or slightly above your knees when sitting on the mattress edge. This typically means a total bed height of 55 to 65 centimetres from the floor. If your bed is too low, use bed risers ($20 to $40 at Canadian Tire) to bring it to the correct height. If it is too high, a lower-profile foundation can help.
Is memory foam good after hip replacement?
Memory foam provides good pressure relief for the hip surgical site, but dense memory foam can make repositioning difficult, which is a problem when you need to change positions using the log-roll technique. A responsive surface (latex or hybrid with pocketed coils) is generally a better choice because it makes the controlled, whole-body movements required during recovery easier to perform.
