CuCu "Ekubo" Lumbar Cushion

A lumbar support cushion designed to fill the gap between the chair and your body—helping improve posture and reduce lower-back strain.

The CuCu Ekubo is developed to “support a beautiful seated posture while easing pressure on the lower back,” making it ideal for long hours on styling chairs, in the car, or in wheelchairs.
The outer fabric has a soft, pleasant touch, while the inside is densely filled with approx. 1 mm microbeads for a springy, moldable feel.
Place it against the backrest, lean into it, and gently pull the sides—
the beads shift to contour to your body for a surprisingly comfortable fit and stable lumbar support.

Durable Construction

■ Double-needle lock stitching reduces thread breakage when pulling the fabric
■ Zigzag "chidor i-stitch" strengthens the cushion against pulling in all directions
■ Reinforced backing fabric in high-stress areas
■ Manufactured after passing third-party physical durability tests

Made in Japan Quality

Every step—from cutting and sewing to bead filling and packaging—is handled domestically to ensure consistent quality.

How to Use

1. Place the cushion on the chair.

2. Sit while leaning your lower back firmly against the cushion.
