5 reasons why thousands of American sleepers choose Cocoon™

Say goodbye to pressure points 🧘

The top layers of your mattress play a huge role in how comfortable it feels. Over time, they can start to sag, support your body less effectively, and create more pressure around your hips, shoulders, and back.

 

Cocoon™ adds a new ultra-dense comfort layer that helps distribute your weight and pressure more evenly — without having to replace your entire mattress.

  • Ultra-thick & plush 1000 GSM

Cloud-like comfort from the very first night ☁️

The moment you lie down, you can feel the difference. Its ultra-dense 1000 GSM filling creates a thick, plush, enveloping layer that supports your body instead of simply flattening under your weight.

 

Within minutes, your bed feels softer, more comfortable, and gives you that sleeping-on-a-cloud feeling.

Plush, yet still breathable 🌬️

A thick mattress topper shouldn’t have to make you overheat. Cocoon™ combines TENCEL™ and Sorona® to deliver that soft, enveloping feel while allowing air to circulate more freely.

 

You get the comfort of an ultra-plush bed without that heavy, stuffy feeling during the night.

Transform your mattress, not your bank account 💰

Has your mattress become too firm or less comfortable? That doesn’t necessarily mean you need to spend thousands of dollars replacing it.

 

Simply add Cocoon™ on top and instantly give your bed a thicker, softer, more inviting surface — for a fraction of the cost of a new mattress.

Set up in 5 minutes. Comfortable night after night ✨

No complicated setup required. Simply place it on your mattress, secure the straps, and put your sheets back on. In about 5 minutes, your bed is transformed.

 

Its quilted construction keeps the filling evenly distributed, while the deep straps help keep it securely in place throughout the night.

Frequently Asked Questions

Is this mattress topper suitable for all types of mattresses?

Yes. Our mattress topper fits all types of mattresses, including innerspring, memory foam, hybrid, and pillow-top mattresses. The reinforced elastic corners fit mattress depths from 8 to 21 inches and stay securely in place throughout the night.

Will it flatten over time?

No. Unlike cheap mattress toppers that flatten within a few weeks, our baffle-box construction and 1000 GSM density resist compression night after night. With proper care, your mattress topper will maintain its plushness for years.

How do I wash my mattress topper?

No. Our comforters are stone-washed to feel soft from the very first night and become even softer with every wash.

Can I put a fitted sheet over it?

Yes, absolutely. Our mattress topper is designed to be used underneath your regular fitted sheet. Just make sure your fitted sheet has deep enough pockets to cover both your mattress and the topper — we recommend a deep-pocket fitted sheet of 15 inches or more for the best fit.

How does the 365-night money-back guarantee work?

On comprend que choisir un sur-matelas en ligne demande de la confiance — c'est pourquoi on vous offre 365 nuits pour l'essayer chez vous. Si après un an vous n'êtes pas convaincu, on s'occupe du retour gratuitement et on vous rembourse intégralement. Vous ne risquez absolument rien.

How long does delivery take?

Free shipping anywhere in the US in 3 to 8 business days. Your mattress topper ships directly from our US warehouse — no overseas delays, no customs.

Est-ce que ça va m'aider avec mon mal de dos ?
