JC Health 17cm Ultra-High Butterfly Pillow | The Specialist Solution for Broad-Shouldered Side Sleepers (Dual Case Set)

Stop settling for standard pillows that leave your neck hanging. The JC Health 17cm Ultra-High Butterfly Pillow is engineered specifically for broad-shouldered side sleepers and larger frames who require a true, high-loft bridge. While typical pillows stop at 12cm, our 3-layer system reaches a towering 17cm of high-density support, ensuring your head never tilts and your shoulders never crush.

The "Cloud-Feel" Difference

Our proprietary high-density memory foam provides the rigid structural support your neck requires, while maintaining a soft, "Cloud-Feel" buoyancy that is unreplaceable.

✨ Why 17cm is the "Game Changer" for Broad Shoulders

Most pillows stop at 12cm. For a side sleeper with broad shoulders, a 12cm pillow leaves a 5cm gap, causing the neck to slump downward all night. Our 3-layer stack bridges that gap completely.

🆕 UPGRADED DESIGN: Zero-Shift Dual High-Loft Cases

• Customer-Inspired Upgrade: Based on real customer feedback and in-store testing, we retired the low-loft cover. Every pillow now includes 2x High-Loft Custom Tencel Cases engineered specifically for 2-layer (14cm) and 3-layer (17cm) setups.

• Deep Sleep Anti-Slip Fit: The high-loft cases wrap tightly around multi-layer stacks to eliminate internal sliding, keeping your height locked in all night.

• Universal Compatibility: Prefer a 1-layer setup? The stretch-fit Tencel holds single cores (11cm) just as securely without bunching up.

🙋 Frequently Asked Questions

❓ How do I adjust the height, and how do I keep my alignment locked in while sleeping?

Add or remove internal layers inside the high-loft Tencel case to dial in your target loft:

• 1 Layer (11cm): Stomach sleepers or narrow frames.

• 2 Layers (14cm): Back or side sleepers with an average body frame.

• 3 Layers (17cm): Side sleepers with broad shoulders or larger frames.

💤 Alignment Tip for Side Sleepers: If you tend to shift at night, position your ear directly inside the Zone C side depression (earhole). This anchors your neck into the cervical bridge, relieves ear pressure, and keeps the pillow from sliding out under you.

❓ Is it safe to use immediately?

Yes. REACH & RoHS certified, arrives 100% hygienic and vacuum-sealed.

❓ How long does expansion take?

Allow 24–48 hours to reach full 17cm loft after opening.

❓ Is the pillowcase washable?

Yes, both Tencel Cotton cases are machine-washable.

❓ What pillowcases are included?

You get 2x High-Loft Tencel Cases tailored for 14cm and 17cm setups. They hold multi-layer stacks snugly so they never shift during sleep, while comfortably fitting 11cm single-layer setups too. Both cases are machine-washable.

❓ Is the memory foam core machine-washable?

No, never submerge or wash the foam. High-density memory foam will lose its structural integrity and support if washed in a machine or soaked in water.

How to Clean & Maintain:

• Air it out: Place the foam in a cool, well-ventilated, or windy area to keep it fresh.

• Vacuum gently: Use a clean vacuum attachment over the foam surface to remove dust particles.

⚠️ Important Safety Note: Never expose the memory foam to direct sunlight. UV rays degrade high-density foam, causing it to harden, discolor, and lose its "Cloud-Feel" bounce-back support. Only wash the removable outer Tencel cases!

❓ Can I use my own pillowcase over the JC Health pillow?

• Yes, absolutely! Slipping your own pillowcase over ours is a great way to match your bedsheet set and add an extra layer of protection.

• The Tencel Difference: While you can use your own cover, our testing shows that sleeping directly on our included Tencel Cotton case offers a noticeably softer, cooler, and more breathable "Cloud-Feel" experience than standard cotton pillowcases.

• Fit Tip: Standard home pillowcases are often designed for lower-profile pillows (10–12cm). If you use a 2-layer (14cm) or 3-layer (17cm) setup, your own pillowcase might feel tight or compress the foam. For the most comfortable, zero-shift sleep, we recommend using our custom High-Loft Tencel cases as your primary layer.

❓ How long will this pillow last, and when should I replace it?

• Proven Core Durability: Built with high-density memory foam engineered to support heavier weight without flattening. Customers using our original base core for over 2 years report it still bounces back and provides the exact same high-loft support as Day 1.

• Personally Tested for Heavy Support: We've been sleeping on the multi-layer setup for over a year straight — the loft hasn't dropped a single millimeter, even under continuous daily pressure.

• Optimal Support Advice: While the foam structure easily lasts for years, we recommend checking your spinal alignment annually. For broad-shouldered side sleepers and larger-frame individuals, keeping your neck properly elevated is critical. Refreshing your pillow setup every 1 to 2 years ensures you never lose that peak cervical alignment and hygiene needed for deep sleep.
