A Seat for Relaxation, Born from the Comfort of Japanese Living - tetra

Daitou Shingu Kogyo’s single-person lounge chair, tetra, has a distinctive triangular silhouette that suits both Japanese and Western interiors.

When you sit down, the cushion naturally adjusts to support your back, guiding you into a comfortable, relaxed position. It feels like a special seat made just for you, creating a moment of quiet luxury.

 

 

The secret of tetra is its unique design, which naturally maintains a 45-60 degree angle, considered ideal for napping.

This gentle incline softly supports your body, helping to relieve fatigue efficiently, even during a short rest.

 

 

Regular Size with Firm Back and Hips Support

This is the regular-size model in the tetra cushion series.

It provides solid support for your back and hips and can be used like a traditional floor chair, making it a popular and versatile choice.

 

 

Bead-Filling and User-Friendly Design for Daily Comfort

The filling consists of approximately 5mm diameter foam beads.

As you shift your posture, the beads move freely, molding perfectly to the contours of your body.

Soft yet supportive, this filling creates an inviting comfortable seating experience.

 

 

 

Light and easy to handle, the cushion can be cleaned or moved with minimal effort

Thanks to the light-weight bead-filling, it can be easily carried with one hand, another feature that adds to its convenience.

The cover is removable for easy care.

The tetra KOKE model is made with high-quality fabrics inspired by traditional Japanese patterns and the moss gardens of Kyoto townhouses, offering both practicality and long-lasting durability for everyday use.
