Brain Sleep's flagship product, the "Brain Sleep Pillow," which has sold over 160,000 units, is a pillow created through research into the brain and sleep. It is a pillow packed with various features to improve the quality of your sleep. There are many points we would like to explain, but this time we will introduce one of the features, "a fit that goes beyond custom-made."

Each time you use it, it will conform to your head and become your own pillow!

The secret behind the Brain Sleep Pillow's comfortable fit is its patented 3-layer structure and 9 gradations. We will introduce these two features that are thoroughly designed to improve the quality of your sleep.

1: Unique patented three-layer structure

The Brain Sleep Pillow may look simple, but it features a carefully designed three-layer structure. From the top, there is a "soft layer" that fits the size and weight of your head, a "support layer" that firmly supports your head and neck, and a "base layer" that supports the pillow while allowing air to escape from underneath. It has a complex structure made of three different thicknesses of resin layered on top of each other. The top "soft layer" is the softest, and the pillow itself changes shape to fit the size and weight of your head. Each time you use it, it becomes your own pillow, just like a custom-made one, perfect for sleeping.

In addition, the bottom "base layer" is the hardest and has a core at the neck, so it firmly supports the neck and reduces the strain on the body. The "support layer" sandwiched between the upper and lower layers is just the right amount of softness to maintain balance, so you don't sink too much and you can feel like you're being pushed back by your hand. The Brain Sleep Pillow has just the right amount of bounce and softness, giving you a weightless feeling as if your head is floating. It is also breathable, so it lowers the temperature of your head while you sleep and improves the quality of your sleep.

2. "9-layer gradation structure" that increases elasticity from the center to the outside

Although the pillow looks uniform, it is actually softest in the center and has a "nine-gradient structure" with increasing elasticity on the left and right sides. When lying on your back, it gently envelops your head, and when lying on your side, it supports your head so it doesn't sink in, so it fits comfortably in any sleeping position. It is said that turning over in bed moderately reduces the strain on your body and improves the quality of your sleep.

The Brain Sleep Pillow's "9 Gradient Structure" helps you turn over smoothly, so you can sleep comfortably until the next morning without being disturbed. It also comes in three different heights (LOW, STANDARD, HIGH), and the height of the pillow is different on the top and bottom, so you can sleep at your preferred height depending on your physical condition and mood each day. You can choose two heights with one pillow, so it's a great deal and doesn't take up space on your bed.

The secret to a great fit! Learn about the manufacturing process!

The pillow remembers the shape of your head and fits like a custom-made product, and its gradient structure with different elasticity provides a special fit that supports you as you turn over in your sleep. What kind of material is it made from and how is it made? We will introduce you to the "4 special features" of the manufacturing process that you are curious about!

1: Weaving polyethylene using patented technology!

The Brain Sleep Pillow is manufactured at Eco World's factory in Oita Prefecture. The material used is a proprietary polyethylene resin. First, the polyethylene resin is melted into threads using a secret machine. Then, using a proprietary patented technology that weaves the resin into a spring shape, it becomes a unique structure called a "woven resin mesh structure" that has excellent water permeability, breathability, and durability.

At the same time, a three-layer, nine-gradation structure is constructed to achieve a fit that exceeds that of custom-made products. After that, the material is cooled and molded using clean, soft water with few impurities from Oita Prefecture, a rice-producing region. The "woven resin network structure" is a patented technology that Eco World has been researching and developing since 1999, and is excellent in durability, flexibility, color, and shape.

2. Cutting by skilled craftsmen to eliminate deviations of even a few centimeters

Most pillows are cut by machine, but the Brain Sleep Pillow has nine gradations, and even a few centimeters of deviation can affect the quality, so skilled craftsmen cut each one by hand, checking the gradation. As a result, all products have a precise nine-gradation structure, maintaining high quality.

3: After cutting, let it rest for 72 hours to stabilize

Because polyethylene resin is elastic, the product is left to rest for 72 hours after cutting to stabilize it. After that, a craftsman visually checks each piece as he cuts it. In addition, the cut surfaces are heat-treated multiple times to smooth them out and make them pleasant to the touch. Although it takes time and effort, it is a very important process in order to deliver products that satisfy all customers. In addition, the polyethylene that is no longer needed after cutting is remelted and processed into resin, making it very sustainable.

4. Each item is inspected by hand under a light

The final process is inspection. To check even the smallest details, each pillow is manually held up to a light for a final check by human eyes. It is necessary to check that there are no foreign objects mixed in, as well as that the weaving is correct and even, so a special rounded light is used to shine light from various angles for a clear view. The Brain Sleep Pillow is made with a lot of care and love, using patented technology and the hands and eyes of skilled craftsmen, resulting in a product that will satisfy customers.

100% recyclable material, a rare find in bedding

The polyethylene material used in the Brain Sleep Pillow is also an environmentally friendly and sustainable material. Scraps generated during manufacturing and items collected for size exchanges are 100% reused. Another great thing about using the Brain Sleep Pillow is that you can effortlessly participate in sustainable activities.

Sleep better with the pillow that's right for you!

It is said that sleep takes up one-third of our lives. By turning busy nights' sleep into restful recovery time, you can have a refreshing morning. To spend every day happily and healthily, please try our carefully crafted Brain Sleep Pillow!
