Red light for your lower back
Not another neck wrap. A full-size lumbar pillow that sits between you and the chair — 36 red and near-infrared LEDs, gentle heat, vibration, and an airbag lift that supports the curve of your lower back. Use it at your desk, in the car, on the sofa, or lying flat in bed.

Built for the way you sit — or lie
- Sit: office chair, car seat, sofa — curved side against your lower back
- Lie: flat on the mattress, pillow under your lower back before sleep
- Cordless: 5,000 mAh battery, no cable while you use it
- One charge, up to 16 sessions: 15 minutes each — about 4 hours with all functions on the lowest level
- 15-minute sessions: automatic shut-off, by design
Four functions. Three levels each. Four buttons.
Most back gadgets do one thing. The Y03 layers four — and you control every one of them with a single press, no app, no manual.
Red light · 108 chips
Each of the 36 LEDs carries two 660nm red chips and one 850nm near-infrared chip — 108 chips total. Visible red for the surface, invisible near-infrared deeper in. Every LED is tested glowing before it ships: 36 red dots, zero dead bulbs.
Heat · 3 levels to 122°F
A graphene heating layer warms through in seconds: 104°F, 113°F, 122°F measured at the surface. Start on low; the high level is genuinely hot — use it over a thin layer of clothing.
Vibration · 3 levels
Three speeds from a soft pulse to a firm massage, for everyday lower-back tension after long sitting or driving.
Airbag lift · 3 levels
A gentle 3-level airbag supports and releases your lumbar curve — the closest thing to a chiropractor’s hands you can keep at your desk.

Straight answers, up front
How hot does it get?
Three surface levels: 104°F, 113°F, 122°F. Start on low; the high level is genuinely hot.
How long does the battery last?
Up to 16 × 15-minute sessions per charge (about 4 hours) with everything on the lowest level; about 13 sessions (3 hours 15 minutes) at the highest level. Charge once, use for a week at 15 minutes a day.
Do all 36 lights work?
Every LED is tested glowing before it leaves the factory. The near-infrared is invisible to your eyes — view it through a phone camera in a dim room and all 36 look brighter, almost white.
