After hip replacement surgery, getting quality sleep is one of the most important parts of recovery — and one of the hardest. Your mattress suddenly matters in ways it never did before. Getting in and out of bed safely, staying on your back as your surgeon instructs, keeping your hip angle within safe limits, and simply not waking up from discomfort all depend on the surface you're sleeping on.
The problem most people run into: their old mattress is either too soft (you sink in and can't push yourself upright), too low (bending past 90 degrees at the hip to get up), or offers uneven surface support that causes you to rotate during the night. None of those are options during recovery.
This guide covers what to look for in a post-op mattress, what to avoid, and which picks make the most sense for recovery — with Saatva earning our Editor's Pick for its combination of firm-but-cushioned support, adjustable base compatibility, and consistent edge support for safe transfers.
We also recommend pairing your mattress with an adjustable base: raising your upper body slightly can reduce hip pressure, and the ability to lift the head of the bed helps with sit-to-stand transitions without bending at the hip excessively.

What to Look for in a Mattress After Hip Replacement
Your needs during post-op recovery are specific. Here's what actually matters:
Medium-firm support. This is the most important factor. A mattress that's too soft allows the pelvis and hip to sink unevenly, which can cause rotation and make it difficult to maintain the neutral positions your surgeon recommends. Medium-firm — typically in the 6 to 7 range on a 1-to-10 scale — gives enough surface resistance to push up from without feeling like a concrete slab.
Consistent edge support. You'll be getting in and out of bed by sitting on the edge first, then swinging your legs up carefully. A mattress with weak edges compresses under your weight when you sit down, tilting your body and forcing your hip into an uncontrolled angle. Look for wrapped coils or reinforced perimeter foam that holds firm under seated weight.
Bed height compatibility. Most orthopedic surgeons recommend a total bed height (mattress plus base or box spring) of around 22 to 26 inches from floor to sleeping surface. This keeps your hip at or above 90 degrees when you sit on the edge — below that, getting up requires bending forward at the hip past safe limits. Measure before you buy.
Adjustable base compatibility. If your recovery plan includes any elevation — and it often should — confirm your mattress works with an adjustable base. Many hybrid mattresses and all-foam models are flex-compatible. Traditional innerspring mattresses with rigid foundations are not.
Low heat retention. Post-surgical recovery sometimes involves inflammation and temperature sensitivity. A mattress with good airflow — hybrid coil systems, latex, or open-cell foam — helps prevent the discomfort of overheating through the night.
Minimal motion transfer. If you share a bed, your partner's movement shouldn't shift your hip position. Individually wrapped coils and foam layers handle this well.
What to Avoid
Very soft pillow-tops. Deep conforming surfaces feel comfortable for a few minutes but create a "bowl" effect around your hips, making it hard to reposition and even harder to push yourself up. The sinking also places uneven lateral load on the hip joint.
Low-profile mattresses on low frames. A 10-inch mattress on a standard platform frame can put your sleep surface at 14 to 16 inches — well below safe transfer height for most post-op patients. Either add a box spring, use a taller adjustable base, or choose a mattress profile of 12 to 15 inches.
All-foam mattresses with no edge reinforcement. Standard memory foam compresses heavily at the perimeter. Great for side sleeping generally, but it's a safety issue when you're doing controlled transfers during recovery.
Mattresses you can't return. Your needs may change as you heal. Prioritize brands with a genuine sleep trial — 100 nights minimum — so you can exchange if the firmness isn't right for your stage of recovery.

Why Saatva Is Our Editor's Pick for Post-Hip-Replacement Recovery
The Saatva Classic earns this position for reasons that are directly relevant to recovery, not just general comfort scores.
First, it comes in two height options: 11.5 inches and 14.5 inches. That profile flexibility matters because hitting the right total bed height for safe transfers is easier when you can choose your starting point. The 14.5-inch version on a standard frame puts most people at a safe sit-down height without needing an additional box spring.
Second, the dual coil system — a micro coil layer over a tempered steel coil foundation — gives a firm, responsive surface that doesn't compress under your weight when you sit on the edge. The lumbar zone provides additional support in the region that bears the most load when you're lying on your back with your hips in a neutral position.
Third, Saatva is compatible with adjustable bases. Raising the head 15 to 30 degrees during sleep slightly offloads the hip and makes it easier to initiate a sit-up without torquing through the joint. The mattress flexes cleanly without developing stress points at the bend zone.
The Luxury Firm option (6.5 out of 10) is the right call for most post-op patients. It's firm enough to resist pelvic sinking and support controlled repositioning, but cushioned enough that back-sleeping through the night doesn't become its own source of discomfort. If your surgeon has you on strict back-sleeping protocols for six to eight weeks, that cushion layer matters.
Saatva also delivers white-glove in-home setup, which matters more than usual when you're in recovery and can't manage a rolled-up mattress yourself.

Sleeping Positions After Hip Replacement: What the Precautions Actually Mean
Surgeons typically give hip precautions for 6 to 12 weeks after surgery, though this varies widely by procedure type (anterior approach precautions differ from posterior approach precautions) and by patient. The standard guidance most patients receive includes some version of the following:
- Sleep on your back, not your side — especially not on the operative side.
- Keep a pillow between your knees if you do roll slightly, to prevent internal rotation of the hip.
- Do not cross your legs or ankles in bed.
- Keep your hip at or above a 90-degree angle when sitting up — do not lean forward to reach your feet.
Your mattress affects how well you can maintain these positions through the night. A surface that causes you to sink or roll makes staying on your back harder. Firm, even support across the full mattress surface — particularly under the lumbar region and upper thighs — keeps your body in the position you set it in when you lie down.
The pillow-between-knees technique works better on a firmer surface as well: on a soft mattress, your legs sink and the pillow shifts. On a medium-firm hybrid, your legs stay roughly where you placed them.
Adjustable Bases and Post-Op Recovery
An adjustable base adds a meaningful tool to your recovery setup, beyond just comfort. Two positions are particularly useful:
Zero-gravity position (head raised 15–30 degrees, legs slightly lifted) reduces pressure on the hip joint and lower back simultaneously. Many patients find this the most comfortable sleeping position during the early weeks of recovery when flat back-sleeping produces its own aches.
Head elevation for sit-to-stand: by raising the head of the bed before you get up, you reduce the range of motion required to move from flat to seated. This can make early-morning transfers significantly safer when hip mobility is most limited.

Frequently Asked Questions
What firmness mattress is best after hip replacement surgery?
Medium-firm — roughly a 6 to 7 on a 10-point scale — is the most widely recommended range. It provides enough surface resistance to push up from and holds your hip in a neutral position during sleep, without the extreme rigidity that causes pressure on the tailbone and lower back during long back-sleeping stretches.
How high should my bed be after hip replacement?
Most orthopedic guidelines suggest a total bed height of 22 to 26 inches from floor to sleep surface. This allows you to sit on the edge with your hip at or above 90 degrees, which is critical for safe transfers during the recovery period. Measure your current setup and adjust your mattress height, base, or frame accordingly.
Can I sleep on my side after hip replacement?
Most surgeons restrict side sleeping — especially on the operative side — for the first 6 to 12 weeks. Some allow sleeping on the non-operative side with a pillow between the knees to prevent internal hip rotation. Follow your surgeon's specific guidance; precautions vary significantly by procedure type and your individual anatomy.
Is a memory foam mattress okay after hip replacement?
Standard memory foam is generally not ideal during early recovery. Deep-conforming foam creates a sinking effect that makes it harder to maintain neutral hip position and significantly harder to push up from when getting out of bed. If you prefer an all-foam feel, look for high-density foam with reinforced edges, or consider a latex hybrid instead.
Does an adjustable base help after hip replacement?
Yes, for many patients. Raising the head of the bed reduces the range of motion needed to sit up, which is helpful when hip flexion is restricted. The zero-gravity position also reduces joint pressure during sleep. Confirm your mattress is adjustable-base compatible before purchasing.
How long do hip precautions last?
This varies. Traditional posterior approach hip replacement often comes with precautions for 6 to 12 weeks. Anterior approach procedures sometimes have fewer or shorter restrictions. Your surgeon and physical therapist will give you the specific timeline and position limits for your case — do not assume a general guideline applies to you.
What should I look for in a mattress for long-term comfort after hip replacement?
Once you're past the active recovery phase, zoned support becomes more relevant — firmer under the hips and lumbar, slightly softer under the shoulders. Good edge support remains useful for ongoing transfers. Latex hybrids and dual-coil innerspring models tend to hold up best for long-term orthopedic comfort without developing the body impressions that gradually shift your sleep alignment.
