The Osaki 4D Zion is designed for customers who want a highly customizable massage chair with precise 4D roller control, automatic body scanning, adjustable shoulder width, extensive SL-track coverage, and focused arm, calf, Achilles, and foot massage.

Best for
Users who want strong 4D massage, adjustable shoulder fit, broad SL-track coverage, detailed arm and calf massage, and specialized foot care.
Massage feel
The Zion delivers a deep, adjustable massage with lifelike roller movement, firm shoulder support, wave-like arm massage, and layered lower-body coverage.
Room fit
The chair requires approximately 5.5 inches of rear clearance. Measure the room, doorway, hallway, turns, and delivery path before ordering.
Key massage features
These are the main Zion features most customers should understand before choosing this chair.
Automatic Body Scan System
The Zion scans the user’s body contours and dimensions before each session. This helps align the rollers more accurately with the shoulders, back, waist, and massage path.
- Maps body shape before the massage begins.
- Helps improve roller positioning along the back.
- Supports a more consistent massage across different users.
4D Mechanism with SL Track Coverage
The Zion combines an advanced 4D massage mechanism with an SL-shaped track that follows the natural curve of the body. The rollers can vary intensity and speed while traveling from the neck and shoulders through the lower back and under the thighs.
- 4D movement supports more precise massage depth and intensity.
- SL-track coverage extends beyond a standard S-Track.
- Designed for a lifelike massage from the upper back through the lower body.
Adjustable Shoulder Massager and Arm Rollers
The shoulder sections offer three width settings—approximately 23, 20, and 18 inches—to better fit different body types. The arm paddles and rollers create a wave-like kneading and pressing motion around the arms.
- Three shoulder-width settings improve fit and support.
- Arm paddles and rollers provide more detailed arm massage.
- Useful for users who want stronger upper-body coverage.
3-Stage Zero Gravity and Space-Saving Recline
Three Zero Gravity positions let users choose different supported reclining angles. The space-saving design allows the chair to complete its recline with approximately 5.5 inches of rear wall clearance.
- Three recline positions provide more posture options.
- Supports a relaxed, weight-distributed massage position.
- Space-saving movement reduces the room needed behind the chair.
Heating Therapy and 32-Cell Air Massage
Targeted heat warms the lower back, calves, and feet, while 32 air cells apply rhythmic compression around the body. The listed heating range is approximately 75–83°F.
- Heat supports comfort in the lumbar, calf, and foot areas.
- Thirty-two air cells add full-body compression massage.
- Works with the roller system for a more complete massage feel.
Automatic Footrest Extension and Calf Rollers
The automatic footrest extends up to approximately 8 inches, including about 4.75 inches through the leg section and 3.25 inches through the calf section. Two calf rollers and four calf air cells provide focused lower-leg massage.
- Automatic extension helps fit users of different heights.
- Two calf rollers target tension along the lower legs.
- Calf air cells add compression around the legs.
Specialized Foot Care
The Zion combines dual foot rollers, Achilles tendon bumpers, reflexology-style ridges, and foot vibration to create a more detailed lower-foot massage from heel to toe.
- Dual rollers provide broad sole coverage.
- Achilles bumpers target the area around the back of the heel.
- Foot vibration adds another layer of comfort for tired feet.
Additional comfort and control features
These supporting features make the Zion easier to use and more complete for everyday home relaxation.
24 Auto Programs
Preset sessions include vitality, recovery, sports recovery, neck and shoulder, back, lumbar, waist and hip, legs, Thai stretch, deep tissue, and other targeted programs.
6 Manual Programs
Manual techniques include kneading, percussion, acupressure, flap, slap, and mixture.
Voice Command
Selected chair functions can be operated through preset commands listed in the owner manual.
Wireless Charging
The integrated charging surface powers compatible devices without requiring a charging cable.
Shortcut Panel
Controls integrated into the armrest provide quick access to commonly used chair settings.
Bluetooth Speakers
Dual Bluetooth speakers provide immersive audio for music, podcasts, or relaxation tracks.
Removable Pillow
Removing the pillow can reduce cushioning and create a stronger massage sensation around the neck and upper back.
LED Lighting
Integrated LED lighting adds a calm visual atmosphere around the chair during evening use.
Adjustable Shoulder Width
The shoulder sections can be adjusted to approximately 23, 20, or 18 inches.
Under-Thigh Coverage
The extended SL-track reaches beneath the thighs for broader lower-body massage coverage.
Calf Air Compression
Four calf air cells work with the rollers to create a firmer lower-leg massage.
Premium Retreat-Inspired Design
The Zion combines advanced massage technology with a refined design created for a calm home retreat.
Before you choose the Zion

- Measure the final placement area in both upright and reclined positions.
- Confirm whether delivery will use the assembled width or disassembled width.
- Allow approximately 5.5 inches of rear wall clearance.
- Ask Tittac about curbside and White Glove delivery expectations before ordering.
Osaki 4D Zion FAQ
What makes the Zion different from a standard massage chair?
The Zion combines a 4D mechanism, adjustable shoulder width, arm paddles and rollers, an extended SL-track, three Zero Gravity positions, calf rollers, Achilles bumpers, foot vibration, and specialized foot care.
How does the adjustable shoulder massager work?
Each side can be adjusted inward to create approximate shoulder widths of 23, 20, or 18 inches. This helps the chair fit different body sizes more closely.
How much wall clearance does the Zion need?
The space-saving design requires approximately 5.5 inches behind the chair for a full recline. Always confirm the final room layout before delivery.
Can the Zion fit through a narrow doorway?
The listed minimum doorway width is approximately 32 inches when assembled and 25.2 inches when disassembled. Delivery access should be confirmed before ordering.
Are the massage, heat, or reflexology features medical treatments?
No. The chair is designed for comfort and relaxation. Its massage, heating, reflexology-style, and vibration features are not medical diagnosis or treatment and should not replace professional healthcare advice.
