Inspired by chimpanzee beds,
the Human Evolution Bed ®︎
WOW × IWATA

A chimpanzee’s bed that is particular about sleeping comfort.
Chimpanzees sleep in trees on a bed made of branches and leaves.
That bed hides many secrets for better sleeping comfort.
The “Human Evolution Bed” was created by taking a hint from these exquisite techniques.
It was jointly developed with Iwata Corporation.
Comfort#01
A slightly smaller “oval” shape.
When a chimpanzee sleeps sprawled out on a bed, its feet stick out of the bed. The slightly smal oval shape replicates that feeling of size. When you lie with your legs outstretched, you can feel the pressure on your heels being released.
The oval shape also allows the length from the head pillow to the foot pillow to vary depending on the direction you lie. Whether you are tall or short, try changing your sleeping direction to find the most comfortable for you.

Comfort#02
“Rocking” like a cradle.
The chimpanzee beds in trees sway comfortably as they roll over in their sleep. Based on recorded footage, we have recreated the same 360-degree swaying as that bed in a tree. The swaying is just like the cradle we felt as children.
Another feature of the bed is that it tilts toward you when you sit on it. It is as if “the bed is coming for you”. Thanks to this, getting in and out of the bed feels easy.

Comfort#03
Exquisite “mattress”.
The chimpanzee bed is neither low rebound nor high rebound, but exquisitely soft. The secret is the many leafy twigs. Each twig and each leaf has a small elasticity, and they all support the body.
We have recreated that sleeping comfort with a mattress made of 100% feathers. The small elasticity of each lightly curved feather gently wraps and supports the entire body.

Comfort#04
A “dish shape” that embraces the body.
The chimpanzee bed is shaped like a dish. The edges are raised, and all directions are pillows. Taking a cue from this, the “Human Evolution Bed” also has pillows in all directions.
Thanks to these “pillows,” when you lie on your back, you can enjoy a sleeping posture that relaxes your torso, as if you were soaking in a hot spring. Of course, even when you lie on your side, the edge of the bed gently cradles your body.

Comfort#05
A sturdy, plate-shaped “foundation”.
To sleep safely in a tree, you need a stable foundation. The chimpanzee builds a sturdy base by breaking and bending branches. Of course, the shape of the base is also “dish-shaped. The Human Evolution Bed reproduces this shape by stretching hemp belts horizontally and vertically across the boldly hollowed out top panel.
The firm base with gentle curves firmly supports your body as if it were holding your relaxed body from below.

Comfort#06
Fine-tune the comfort for today’s you.
The Human Evolution Bed allows for fine-tuning. You can change the curve of the base by adjusting the hemp belt, or change the height of the pillow by lightly tapping the mattress to move the feathers inside.
The way you prefer to sleep depends on how you spend your day, whether it is a day of exercise or a day of heavy desk work. Why not take a moment before going to sleep to find the perfect sleeping position for the you of that day?
