Most lumbar pillows are flat. Your spine isn't.

Standard cushions just sit behind your back — they fill space, but they don't actively support the spine's natural curve. Kummo's dual-wing structure was developed using chiropractic insights into how the lumbar spine actually behaves during long sitting. The wings hug the sides of your lower back, the central bolster fills the lumbar gap, and the high-density LUMEX™ foam holds its shape through 8+ hour days without flattening.

It's not a comfort pillow. It's a corrective support system — and that's the difference your back will feel.

Yes — Kummo is designed to work on most standard chairs, including office chairs,
gaming chairs, dining chairs, and car seats.

The seat cushion measures 17" × 15" × 5" (43 × 38 × 13 cm) and sits on top of any
flat seat. It works with mesh, leather, and fabric chairs.

The lumbar pillow measures 16.5" × 14" × 4.3" (42 × 36 × 11 cm) and attaches with
an adjustable elastic strap that fits most office and gaming chair backrests. The
strap wraps around the chair back, so no installation needed.

If you're unsure whether it fits your specific chair, just measure your seat
before ordering. And remember — you have 30 days to try it risk-free.

Note: The seat cushion adds 5" (13 cm) to your sitting height. After installing
it, you may need to lower your chair so your elbows rest comfortably at desk
level. Most office chairs have enough adjustment range to accommodate this.

Most users notice meaningful changes in back comfort and posture within 2-3 weeks of consistent daily use (4+ hours per day). Some feel relief within the first week.

Here's a realistic timeline:

• Days 1-3: Firmer than expected — adjustment period begins
• Days 4-7: Back muscles start relaxing into proper alignment
• Week 2-3: Noticeable reduction in lower back fatigue and stiffness
• Day 30: If you're not seeing real improvement, we'll refund you in full

The longer you sit on Kummo, the faster your body adapts. Consistency is everything.

Kummo is designed to support your spine's natural alignment, not replace your back muscles. Unlike rigid braces or posture correctors that immobilize you, Kummo lets your muscles continue to engage — it just gives them the right structure to engage against.

Used daily, Kummo helps your body relearn proper posture rather than become dependent on external support. Many users report that their posture improves even when they're not using Kummo, because their muscles have adapted to a healthier resting position.
