CuCu “Ekubo” Lumbar Cushion

Close the Gap Between Chair and Body for Better Posture

This “Comfort for Your Lower Back” cushion helps maintain proper posture and relieves pressure when sitting for long hours—ideal for styling chairs, car seats, or even wheelchairs.

The CuCu Ekubo Lumbar Cushion was developed to “improve sitting posture and reduce lower back strain.”
The cover is smooth and soft to the touch, while the inside is densely filled with ultra-fine beads (approx. 1 mm diameter), creating a mochi-like, springy texture that fits perfectly to your body.

Simply place it on your chair, lean back, and gently pull both sides—the beads shift and mold around your back to provide a surprising “Aha!” moment of comfort and support.

Designed for Comfort and Durability

• Strong stitching: Uses dual lock-stitching around the edges and zigzag “chidoristitch” for extra strength in all directions.

• Reinforced fabric: Backed in high-stress areas to prevent tearing.

• Quality assured: Each cushion passes third-party material testing before production.

Proudly Made in Japan

Every step—from cutting and sewing to bead filling and packaging—is done domestically to ensure consistent quality and full compliance with manufacturing standards.

How to Use

1. Place the cushion on your chair or car seat.

2. Sit back firmly against it.

3. Lightly pull the cover fabric to the left and right.

4. Feel it fit perfectly to your lower back!
