by After hip replacement surgery, you need a medium-firm mattress with strong edge support so you can transfer safely in and out of bed during recovery. Our top pick is the Amerisleep AS3: its HIVE 5-zone layer cushions the hip and surgical site while keeping the spine neutral. The Saatva Classic is the best coil-hybrid alternative with outstanding edge support and white-glove delivery, both valuable when mobility is limited.
Amerisleep AS3
9.1/10
- HIVE 5-zone support cushions the hip while firming under the lumbar, the key combination for post-surgical recovery
- Partially plant-based Bio-Pur foam relieves pressure at the surgical site without deep sinkage that strains getting up
- CertiPUR-US certified, no harsh off-gassing during bed rest
- 100-night trial starts your recovery period with a full return option
- Edge support is a step below the Saatva's (8.0/10 vs 10/10 in NapLab testing); the AS3 Hybrid adds perimeter coils if edge transfers are a concern
- Sleepers over 230 lb may prefer the AS3 Hybrid, which adds a coil base, for more structural support during recovery
The AS3 hits medium (5/10), cushions the hip joint without bottoming out, and arrives in a box with free shipping so there is no need to coordinate a delivery crew while you are still on crutches. The 20-year warranty means you are not buying a recovery mattress you will outgrow.
Why the mattress matters more after hip replacement
Hip replacement surgery replaces the damaged joint with an artificial joint made of metal, ceramic and/or plastic. For the first 6 to 12 weeks, the surrounding muscles, tendons, and scar tissue are healing, which means every transfer in and out of bed puts real mechanical stress on the new joint. The wrong mattress makes this worse in two specific ways.
Too soft: a plush surface lets the hip sink unevenly, rotating the new joint away from neutral position. A very soft surface also makes it harder to keep the hip in a safe position and to get up without bending too far.
Too firm: a hard surface puts concentrated pressure directly on the iliac crest and the incision site, which causes the kind of localized pain that breaks sleep, and poor sleep makes recovery harder.
Medium-firm (5 to 7 on a 10-point scale) consistently splits the difference. It provides enough resistance to keep the pelvis level and enough compliance to cushion the surgical site.
Edge support: the factor most guides skip
When you are on crutches or a walker, you will sit on the edge of the mattress dozens of times a day. If the edge collapses under your weight, you cannot use your arms to push yourself upright without bending the hip past the 90-degree precaution that protects the new joint for the first several weeks. A mattress with reinforced edge coils or dense perimeter foam remains stable under that seated load and turns a hazardous transfer into a controlled one.
Total bed height also matters. With a standard 7-inch frame and a 12-inch mattress, you land at 19 inches, which may be too low: your hips should sit slightly higher than your knees when you sit on the edge, so you can stand without excessive hip flexion. Your therapist can confirm the right height. A 14.5-inch profile mattress on the same frame gets you to 21.5 inches, close enough to use a small bolster if needed.

Saatva Classic
8.9/10
- Outstanding edge support (10/10 in NapLab lab testing, 2.25" sitting sinkage) makes transfers much safer during recovery
- Free white-glove delivery with in-room setup, useful when you cannot maneuver a mattress yourself post-surgery; the AS3 requires setup assistance
- 365-night trial covers the full recovery arc from acute phase through rehabilitation
- Available in a 14.5" height for a taller bed (the 11.5" version is the one for adjustable bases)
- $99 return fee applies, not zero-cost like some competitors
- Moderate motion isolation, the coil bounce can be felt by a partner
- Heavy at approximately 110 lb for the queen, difficult to rotate or reposition without help
For anyone whose surgeon recommended firm footing when getting up, the Saatva Classic in Luxury Firm offers a very stable edge (10/10 in NapLab testing), plus free white-glove setup that is genuinely useful when you are still on a walking aid.
WinkBed (Luxury Firm)
8.7/10
- Reinforced perimeter coils for strong edge support
- Outstanding pressure relief across all positions, important for side recovery sleeping
- Fiberglass-free construction, per WinkBed
- Lifetime warranty with free shipping and returns (no return fee)
- 120-night trial is shorter than Saatva's 365-night option
- Not available in a profile above 13.5 inches, slightly lower than the Saatva for bed height considerations
- $49 exchange fee if you need to swap firmness levels
WinkBed builds the perimeter with reinforced coils. For hip replacement recovery where transfers are a daily safety concern, the reinforced perimeter coil system is a tangible mechanical advantage over most hybrids.

Sleep position after hip replacement
Most surgeons recommend back sleeping for the first 6 to 12 weeks after hip replacement. The hip precautions, specifically no bending past 90 degrees, no crossing the legs, and no rotating the foot inward, are easiest to maintain on your back. A medium-firm mattress lets the lumbar and sacrum settle without pushing the healing hip into rotation.
- Back sleeping: a pillow between the legs helps keep them apart; ask your surgeon before putting a pillow under the knees, since it bends the hip.
- Side sleeping: follow your surgeon's clearance and approach-specific instructions about which side to use and whether to place a pillow between the knees.
- Stomach sleeping: Follow your surgeon's approach-specific restrictions and wait for their clearance before using this position.
If back sleeping is difficult due to pre-existing lumbar problems, an adjustable base at a gentle zero-gravity position may be easier to tolerate than a flat surface; ask your surgeon first, since raising the head and knees bends the hip.
What to look for in a mattress after hip replacement
Firmness: Medium to medium-firm (5 to 7 out of 10). Soft mattresses allow excessive pelvic sinkage; extra-firm mattresses concentrate pressure at the iliac crest. The medium-firm range allows the pelvis to settle into neutral without rotating.
Edge support: Look for reinforced perimeter coils or dense edge foam. In lab testing the difference between a mattress with 2.25 inches of edge sinkage and one with 5 inches is significant when you are doing a daily transfer on an unstable hip. Coil hybrids and Euro-top hybrids tend to outperform all-foam beds here.
Height: Higher profiles (13 to 15 inches) on a standard frame bring total bed height closer to the 22 to 26-inch range that reduces hip flexion during transfers. If your frame is low, a firmer topper can add height without changing the support characteristics.
Trial length: Hip replacement recovery spans 3 to 6 months for full tissue integration. A 100-night or longer trial covers the acute phase. A 365-night trial covers the full rehabilitation arc, which is why the Saatva Classic's trial period is particularly practical for this use case.
Delivery: If you are in the immediate post-surgical phase, white-glove delivery and setup matters. Unboxing a compressed mattress, rolling it out, and lifting it into position is physically demanding. Saatva delivers assembled, sets it up in the room, and removes your old mattress.
For hip replacement recovery, choose medium-firm with reinforced edge support. The Amerisleep AS3 is our top all-foam pick for pressure relief and a 100-night trial; the Saatva Classic is the best hybrid alternative for its outstanding edge support, white-glove delivery, and 365-night trial that spans the full recovery window.
Frequently asked questions
What firmness mattress is best after hip replacement?
Medium-firm (5 to 7 out of 10) is the consistent recommendation. Soft mattresses allow the hip to sink into a rotated position, which strains the new joint capsule. Firm mattresses put direct pressure on the surgical site and the iliac crest, disrupting blood flow and sleep quality. Medium-firm keeps the pelvis level and cushions the pressure points without deep sinkage.
How important is edge support after hip surgery?
Very important. You will transfer in and out of bed multiple times per day during recovery, and each transfer requires sitting on the edge and pushing to standing. A mattress edge that collapses under your weight forces you to bend the hip past 90 degrees to compensate, which is the primary dislocation precaution you are trying to avoid. Coil hybrids with reinforced perimeter coils usually do better than all-foam beds here; a bed rail adds security with any mattress.
How long after hip replacement before I can sleep normally?
Most patients can return to their preferred sleep position after 6 to 12 weeks, once the surgeon confirms the joint capsule has healed enough to release hip precautions. Back sleeping is almost always required for the first 6 weeks. Side sleeping on the non-operated side with a pillow between the knees is typically cleared between weeks 6 and 12. Follow your surgeon's specific instructions, as individual recovery timelines vary.
Can a mattress topper help during hip replacement recovery?
A medium-density topper (2 to 3 inches of latex or gel foam) can add cushioning to a firm mattress without adding enough softness to compromise edge support. However, if your existing mattress is soft or sagging, a topper will not restore the structural support you need. A new medium-firm mattress is more reliable than patching a failing surface with a topper.
Is memory foam or a hybrid better after hip replacement?
Both can work, but they make different tradeoffs. Memory foam provides better pressure relief at the surgical site and stronger motion isolation. Hybrid coil mattresses offer better edge support and easier repositioning. For the first 6 to 8 weeks when edge transfers are the daily priority, a hybrid has the advantage, though the AS3's edge (8.0/10 in NapLab testing) is decent for an all-foam bed. For chronic hip pain without the acute recovery demands, memory foam pressure relief may be more valuable.
