Keeps Cushion - "The Pillow for Your Hips"

A seat cushion designed to upgrade any chair and help maintain ideal posture.

Created using bedding technology from nishikawa, this cushion supports the sacrum and sit bones to keep you comfortably seated for long hours.
Modern people sit an average of 7 hours a day, often leading to poor posture, back pain, and hip fatigue.
The Keeps Cushion helps stabilize pelvic alignment and maintain a healthy sitting posture effortlessly.

3 Key Benefits

■ Upgrade your everyday chair
Improves comfort while helping you maintain proper posture.

■ Comfort for long desk work
Rich, resilient urethane distributes pressure while the ventilated structure helps prevent heat buildup.

■ Co-developed with Kanazawa University
Based on sleep-science research from nishikawa, now applied to “comfortable sitting.”

Triangle Support System® (Patent Pending)

A unique technology that stabilizes bone positioning to guide the body into an ideal seated posture.

1. Sacrum Support
   Gently nudges the sacrum to keep the pelvis at a healthy angle.

2. Sit-Bone Pocket
   Holds the sit bones in place to prevent sliding forward.

3. Thigh Slits
   Distributes pressure across the thighs to reduce fatigue.

By supporting the sacrum, sit bones, and thighs, the cushion naturally maintains a well-aligned pelvic position, reducing strain and keeping you comfortable for long periods.

Optimized Pressure Distribution

Inspired by pillow ergonomics, nishikawa analyzed ideal pressure balance:
Sit bones 1.0 : Sacrum 1.7 : Thighs 1.0

This ratio minimizes sit-bone pressure and reduces fatigue.

■ Without a cushion: ~85% of pressure concentrates on the sit bones
■ With Keeps: Reduced to ~30% with pressure distributed across the entire surface

Additional Comfort Features

■ Breathability – Air holes around high-contact thigh areas prevent heat buildup
■ Anti-slip base – Keeps the cushion securely in place
■ Antibacterial cover – For daily hygiene
■ Washable cover – Removable and washable for easy cleaning
■ Durable high-resilience foam – Long-lasting support with minimal bottoming-out

Keeps Brand Concept

Based on nishikawa’s long-standing sleep-science expertise, Keeps is designed to reduce strain from long sitting hours by supporting proper pelvic and spinal alignment.
