Why You Need a Thick Mattress Topper

A thick mattress topper isn’t just an accessory—it’s a sleep upgrade. While thin toppers can add a slight cushion, going for a 10cm thick mattress topper makes a dramatic difference. Here’s why:

Extra comfort: If your mattress feels like a rock, an extra thick mattress topper can add that plush, cloud-like softness.
Better support: A thick topper contours to your body, reducing pressure points on shoulders, hips, and back.
Budget-friendly fix: Instead of spending thousands on a new mattress, a topper extends the life of your current one.
Temperature control: High-quality thick toppers often use gel-infused memory foam to keep you cool at night. If overheating is your biggest issue, the Newentor cooling mattress topper is an excellent choice for staying comfortable year-round.
Waterproof protection: For families with kids or anyone worried about spills, a waterproof mattress topper adds an extra layer of defense while keeping your sleep surface fresh and hygienic.

💡 According to the Sleep Foundation, upgrading your sleep surface—even without changing your mattress—can improve comfort and reduce body pain.

【Mattress Thickness Guide】How Thick Should Your Mattress Topper Be？

Not all toppers are created equal. Some are just 3cm thick, while others go up to 10cm thick mattress toppers. But which thickness is right for you?

3–5cm: Great for adding light cushioning if your mattress is already supportive.
7cm: A balanced option for softening firm mattresses without too much sink.
10cm extra thick mattress topper: The ultimate choice if your mattress is old, sagging, or simply too uncomfortable. It offers a hotel-like feel, deep pressure relief, and lasting durability.

If you’re a side sleeper, a thick mattress topper is particularly helpful because it cushions shoulders and hips. Back and stomach sleepers may prefer medium thickness unless they want a more plush experience.

FAQs about Thick Mattress Topper

How long does a thick mattress topper last?

A high-quality topper, like the Newentor mattress topper, can last 10–15 years with the right care. Regular rotation, keeping it clean with a mattress protector, and ensuring it sits on a supportive base will extend its life.

Can a thick mattress topper replace a mattress?

Not exactly. A thick topper can improve comfort and support, but if your mattress is sagging or structurally broken, no topper will fully fix it. Think of it as a booster—it refreshes a mattress that’s too firm, too soft, or just slightly worn, but it doesn’t replace the foundation of a good mattress. If your bed has truly reached the end of its life, you’ll get far better long-term results by investing in a new mattress, such as the Newentor Hybrid Mattress, which combines supportive pocket springs with plush memory foam. Then, you can always add a thick topper on top for an extra layer of comfort.

Is a thick mattress topper good for back pain?

Yes—especially if your mattress is too hard or uneven. A thick topper provides extra cushioning, relieves pressure points on the shoulders and hips, and encourages proper spinal alignment. Newentor’s memory foam toppers, available in both soft and firm versions, are great for tailoring the support to your needs.

Does thickness really matter?

Absolutely. Thickness directly affects comfort and support. A 5cm topper works well if you just need a slight comfort boost. A 7cm topper balances softness and support, making it the most versatile option. And if you need the ultimate plush feel or want to revive an old mattress, a 10cm extra thick topper makes a huge difference.

Bottom Lines

If your mattress feels too firm, old, or simply uncomfortable, don’t rush to buy a new one just yet. A thick mattress topper could be the affordable solution you need for deeper, better sleep. From reducing pressure points to extending your mattress life, a 10cm thick mattress topper is a real game-changer.

After testing different options, Newentor thick mattress topper delivers the best balance of softness, support, and cooling comfort. Investing in your sleep doesn’t have to mean spending thousands—it can start with the right topper. Sweet dreams start here.
