The L-WAVE pillow was developed by the mattress specialist manufacturer Rubik JP, drawing on their experience and technology. They meticulously designed it to provide optimal height and firmness, supporting comfortable sleep positions.

The Proprietary Technology Enhances Comfort While Facilitating Rolling Over

3D Shape Pillow
The L-WAVE pillow uses Silky Fiber, a finely woven polyethylene resin, as its filling material. The center is designed to be the lowest point, gradually curving outward. It allows for natural movement during sleep and ensures high-quality rest.

Its height can be adjusted by altering the top and bottom sections.
Back sleepers position their necks on the lower side, while side sleepers use the higher side.

Firmness of the pillow
It is designed to be firmer in the middle than on both sides compared to general pillows. By adjusting the
Silky Fiber’s density, it provides support for changing positions during sleep, making it comfortable for both back and side sleeping.

Ensure Easy Maintenance and Hygiene

The L-WAVE pillow gradually conforms to the shape of the user’s head with use. Within approximately one week of use, it adapts to the user’s head shape.

If the filling material starts to sag, applying water at around 40°C will restore its original form.

The Silky Fiber filling offers excellent breathability, preventing moisture buildup, dust mites, mold, and house dust. Its mesh-like structure maintains an optimal density, creating layers of air. Additionally, it ensures a comfortably cool sleep environment year-round.

It is also easy to wash and dries quickly. Compared to other materials like urethane, it resists heat and humidity buildup, promoting restful sleep by facilitating a smooth decrease in core body temperature.

Its pillowcase is machine-washable, making it ideal for those concerned about pillow odors or anyone who wants to maintain cleanliness.

Eco-Friendly Materials

The Silky Fiber is a fiber material made from special resin that is 100% recyclable. It’s a fully circular product that allows customers to recycle their used pillows and transform them into new ones.

The pillowcase is made of high-quality polyester fibers that have been reborn from plastic recovered from the sea.
