★ ★ ★ ★ ★‘‘We stayed at a modern ryokan and they had the tetra beanbags. We sat in them and loved the aspect of sitting closer to the floor and having our back/spine supported. We enjoyed them so much that we had to have them at our home’’ — Customer S from the USA

Why choose tetra?
✔ Superior Back Support
Unlike ordinary bean bag chairs, tetra is designed to distribute body weight evenly and provide proper back support. Traditional bean bag cushions may concentrate pressure on the hips and lower back, while tetra helps reduce pressure points and creates a more comfortable seating experience.
✔ Premium Bead Filling
tetra is filled with 5 mm beads that are larger than those typically found in ordinary bean bag chairs. This unique bead size helps create a balance of comfort and support, allowing the chair to conform to your body while maintaining stability.
✔ Lightweight and Easy to Move
tetra can be lifted easily using the built-in handle. Even children can move it safely. It is especially convenient when cleaning floors or rearranging furniture.

The vivid color tones of Canvas #8 make it an ideal accent for white color schemes, minimalist interiors, and modern home décor. Choose from 10 high-saturation colors to complement your living space and add personality to your bean bag.

Frequently Asked Questions
Q: There are too many tetra options. How do I choose the right one for me?
A: Please refer to our tetra Selection Guide, which helps you compare all models and choose the one that best fits your needs and lifestyle.
Q: Are tetra covers washable?
A: All of our covers are removable for easy care. Whether they are washable depends on the fabric type. We generally recommend gentle hand washing for all materials to maintain quality and durability.
You can check the full list of washable fabrics in our tetra Selection Guide above.
Q: Will it collapse after use?
A: Over time, the internal foam beads may naturally compress and slightly decrease in volume due to long-term use and body pressure.
If this occurs, refill beads are available for purchase to restore volume and comfort, helping your tetra product maintain its original feel.
