Keeps Lumbar Cushion – “A Pillow for Your Lower Back”

Support Your Posture Comfortably — Just Attach It to Your Everyday Chair

Developed by nishikawa, a leading Japanese bedding brand, the Keeps Lumbar Cushion applies pillow ergonomics to sitting posture.
By gently filling the gap that forms between your lower back and the chair, it supports your spine just like a pillow supports your head — softly, naturally, and comfortably.

The cushion promotes a healthy, balanced posture by supporting three key areas: the lumbar spine, iliac bone, and rib area.

W Fit System® (Patent Pending)

nishikawa’s original W-shaped design stabilizes bone alignment and helps maintain the natural S-curve of the spine, reducing fatigue during long hours of sitting.

1. Lumbar Point
Applies gentle pressure to support the lower spine and encourage correct posture.

2. Iliac Point
Side supports hold the pelvis securely as you lean back, preventing slouching.

3. Rib Point
Provides soft support under the rib area for comfortable upright sitting.

Together, these three points create balanced, three-dimensional support, helping you maintain a relaxed yet ideal sitting posture for extended periods.

Pressure Distribution

Without lumbar support, pressure tends to concentrate around the sitting bones.
When using the Keeps Lumbar Cushion, this pressure is redistributed from the seat to the back, relieving strain and enhancing long-term comfort.

Additional Features

• Antibacterial & Washable Cover: The outer fabric has an antibacterial finish and can be removed for washing to maintain cleanliness.

• Adjustable Strap: Securely fits most chairs (backrest circumference approx. 80–140 cm).

Brand Concept – “Keeps by nishikawa”

Modern people sit for an average of 7 hours a day, often resulting in poor posture and lower back pain.
Born from nishikawa’s sleep science, Keeps helps stabilize your sitting position — supporting the pelvis and spine comfortably for ideal posture throughout the day.
