Can You Put a Mattress Topper on Memory Foam Mattress?

Yes — you can put a mattress topper on a memory foam mattress, and it’s often an effective way to soften a bed that feels too firm. When you add a topper, it becomes the main surface you feel, while the memory foam underneath still contributes to overall support and contouring.

A topper may slightly reduce the heat that reaches the memory foam, which can make the foam respond a bit more slowly, but it won’t stop it from contouring. The effect depends on the topper’s material, thickness, and your body weight. Heavier sleepers will still feel more of the deeper memory foam layers, while lighter sleepers may feel mostly the topper.

If you want more softness without the “stuck” feeling, choose latex or polyfoam instead of memory foam. These materials add comfort while keeping the surface more responsive.

A topper is worth trying if the mattress is simply too firm and not sagging. Just make sure you choose one with a good return policy, since the only way to know if the combination works is to sleep on it. And in the next section, we’ll go through the real pros and cons so you can decide whether this combination is right for you.

The Advantages and Disadvantages of Putting a Topper on a Memory Foam Mattress

Pros

Extra Cushioning: Memory foam is already comfortable, but a topper can add an extra layer of softness or support, giving your mattress a more luxurious, cloud-like feel.
Adjusts Firmness: If your mattress feels too firm or too soft, the right topper can fine-tune the comfort level to better match your sleeping preferences.
Better Temperature Control: Since memory foam can trap heat, a cooling topper helps improve airflow and keeps you from overheating at night.
Mattress Protection: A waterproof mattress topper also acts as a protective layer, preventing stains and wear, helping your mattress last longer.

Cons

Can trap heat if it’s not a cooling design: A common concern is: “Are memory foam mattress toppers hot to sleep on?” Traditional foam traps heat, but modern gel-infused foams are much cooler.
Won’t fix severe mattress sagging: A topper can mask small dips, but if your mattress has deep body impressions, it’s better to replace it.

Note: If your mattress is severely sagging, a mattress topper won’t fix the problem. The best solution is to replace it with a high-quality mattress. The Newentor Hybrid Mattress uses a memory foam + 7-zone pocket spring design that follows ergonomic principles, giving you proper support and a restful night’s sleep.

[Buying Guide] How to Choose a Mattress Topper Best for You?

Choosing the right topper depends entirely on your sleep style and the problem you're trying to solve. Here’s how to pick the perfect one.

1. Match the topper to your sleeping position

Side sleepers: Choose a soft to medium memory foam topper (5–7.5cm thick).
Back sleepers: Medium firmness for balanced support.
Stomach sleepers: Avoid soft memory foam; choose firmer latex instead.

2. Consider firmness adjustment

Too firm → Choose a soft or medium memory foam topper.
Too soft → Choose high-density memory foam or a latex topper.

3. Check topper thickness

3–4cm: Light comfort adjustment
5–7cm: Best for pressure relief & back pain
8–10cm: Maximum plushness (hotel-style softness)

4. Choose cooling materials if you’re a hot sleeper

Look for gel-infused memory foam, bamboo covers, or ventilated foam. These features improve airflow and reduce heat retention.

5. Check certifications

Ensure the topper is made with safe, long-lasting materials such as CertiPUR-US® and OEKO-TEX®.

6. Check return policy & warranty

Brands offering sleep trials are more trustworthy. Memory foam toppers often come with 100-night trials, allowing you to test comfort risk-free.

The firmness is adjustable, allowing you to fine-tune the feel to your preferred comfort level. Plus, the anti-slip bottom design keeps the topper securely in place, preventing shifting throughout the night.

If you want a topper that adapts to your body, keeps you cool, and stays put—Newentor delivers a truly comfortable, supportive upgrade.

FAQs about Memory Foam Topper on Memory Foam Mattress

1. Can I put a memory foam mattress on top of another memory foam mattress?

No. Stacking two full memory foam mattresses can make the bed unstable, reduce support, and trap excess heat. Memory foam performs best on a firm base—not another thick foam layer.

If your mattress feels too firm or uncomfortable, a 5–10cm memory foam topper is a safer, more effective option than adding a second full mattress.

2. What is the best mattress topper for a memory foam mattress?

For pressure relief / back pain: High-density gel memory foam contours to your body and reduces shoulder, hip, and lower-back pressure.
For cooling: Choose gel-infused or ventilated memory foam with a breathable bamboo or TENCEL cover.
For firmness adjustment: Soft toppers add plushness; firmer latex or high-density memory foam improves support.

A strong all-round pick is the Newentor Memory Foam Mattress Topper, offering gel-infused foam, adjustable firmness, 5/7/10cm thickness options, and an anti-slip base—ideal for upgrading a memory foam mattress without losing support.

3. What do hotels put on top of mattresses?

High-density memory foam toppers for balanced support and pressure relief.
High-loft fibre toppers to create a plush, cloud-like sleeping surface.

Luxury hotels typically choose toppers that deliver both softness and support so guests sleep comfortably across all sleep positions.

Note

The Newentor mattress topper is used and endorsed by the luxury Brighton Savoy Hotel in Australia.

Bottom Lines

A memory foam topper can be an effective way to soften a too-firm memory foam mattress, boost pressure relief, and improve cooling—provided the mattress isn’t sagging.

Choose your topper based on sleep position, thickness, and temperature needs. For an easy, versatile upgrade, the Newentor Memory Foam Mattress Topper offers cooling gel foam, adjustable firmness, and multiple thickness options.
