Dear Customer, We Apologize!

Sleep Welly is produced with 100% natural materials, making it more expensive than other pillows.

With the intention of innovating better sleep, we aimed to create a pillow without compromising on raw materials.

However, even if the price is higher, if you are looking for the right sleep with a sturdy and perfect cervical pillow,

You’ve come to the right place.

#SleepWelly #SeoulUniversityPillow

Why do Seoul University students think pillows are important?

It's because they earnestly wanted 8 hours of restorative sleep even if they only had 5 hours.

But, might it be that what is even more earnest is all of us?

With childcare, housework, and work, we are all exhausted.

We live all day as if carrying a bowling ball on our neck.

Head weight = 5.5~6.5kg = 1 Bowling ball

Even slightly nodding our head increases that weight by over 4 times.

Increase in load based on head angle:

• 0°: 5kg
• 15°: 12kg
• 30°: 18kg
• 45°: 22kg
• 60°: 27kg

This accumulated cervical damage recovery is only the time spent free from gravity while sleeping.

But incorrect sleep accumulates fatigue instead of recovery.

The start of the day is from sleeping well rather than just sleeping.

Frequently Asked Questions

1. Can I use the pillow with a heating pad?
   - Natural latex is sensitive to heat, so please use heating mats below 40°C.
   - If using stronger heat, we recommend placing an additional cover beneath the pillow.
2. Can I use another cover instead of the original?
   - Yes, but we recommend using the original cover made of premium breathable modal fabric for its superior absorption and ventilation.
3. Is it necessary to always use a pillow cover?
   - Yes, since natural latex is difficult to wash, please use a cover to prevent contamination.
