Keeps Lumbar Cushion - "The Pillow for Your Lower Back"

Comfortable posture support by simply attaching it to your everyday chair.

Designed using pillow ergonomics, this lumbar cushion gently fills the gap created when sitting in an ideal posture on a standard chair. The Keeps Lumbar Cushion softly supports the lower back like a pillow, helping maintain proper posture with ease.

W Fit System® (Patent Pending)

nishikawa original 3-point support technology
Supports the lumbar vertebrae, iliac bones, and lower ribs.

1. Lumbar Point
   Provides gentle pressure to help maintain a healthy sitting posture.

2. Iliac Points
   Side pads tighten and hold securely when you lean back, stabilizing the pelvis.

3. Rib Point
   Softly supports the lower rib area for added comfort and alignment.

The cushion’s W-shaped structure supports these 3 key areas, helping the spine maintain its natural S-curve. This reduces fatigue and keeps you comfortably seated for long periods.

Ideal S-Curve Alignment

The unique W-shaped design stabilizes the pelvis with the iliac points, while the lumbar and rib points guide the spine into an ideal posture.
When weight is applied to the lumbar point, the iliac points tighten gently—helping you maintain correct posture naturally.

Using the Keeps Lumbar Cushion can also increase the lumbar lordosis angle (healthy lower-back curve).

Pressure Redistribution

■ Without a lumbar cushion:
Pressure concentrates heavily on the sit bones.

■ With Keeps:
Pressure is distributed from the seat surface to the back support, reducing load on the lower back and allowing longer, more comfortable sitting.

Comfort Features for Everyday Use

■ Hygienic & Washable
Removable cover with antibacterial finish.

■ Durable High-Resilience Foam
Provides long-lasting support.

■ Secure Fit With Adjustable Strap
Fits chairs with a backrest circumference of approx. 80–140 cm.

■ Perfect Match With the Keeps Seat Cushion
Using both together enhances pelvic and spinal alignment.
