Key takeaways
- Voice control: handy for starting and stopping programs without finding the remote.
- Wireless charging pad and USB port: convenient for long sessions.
- Bluetooth speakers and lighting: nice extras but not a reason to choose the chair.
- App control: an alternative to the handheld remote.
The Kyota Yutaka M898 is a 4D massage chair with a long 49-inch SL-track, calf kneading, foot rollers and a fit range up to about 6’7″ and 300 lb, which makes it one of the more practical choices for tall and larger users who still want a chair that sits about 2 inches from the wall. Its weaknesses are size and weight: it is 35 inches wide and over 300 lb, so it needs a real spot in the room.
This review focuses on fit, footprint and what the 4D mechanism adds, so you can judge whether the M898 suits your body and space.

What 4D Adds Over 3D
A 3D chair can push rollers deeper into the back. A 4D chair adds control over the speed and rhythm of each motion, so a kneading stroke can slow down at the point of contact and speed up on the return, closer to how a therapist’s hands move. In practice, 4D chairs feel less mechanical and more varied during long programs.
The intensity on the M898 is generally described as medium-firm to deep tissue. Users who are sensitive to pressure should start with the lowest depth setting and the gentler auto programs.
Fit: The M898’s Main Strength
Most mid-range chairs top out around 6’1″ to 6’2″. The M898’s longer track and broader frame let it accommodate users up to about 6’7″. The 22-inch shoulder width also helps broad-shouldered users, since narrow chairs pinch the arms during air compression.
| User | Fit on M898 | Notes |
|---|---|---|
| Under 5’4″ | Limited | Below the stated range; neck rollers may sit too high |
| 5’4″ to 6’0″ | Good | Comfortable in all programs |
| 6’0″ to 6’7″ | Very good | Main advantage over 6’2″-limited chairs |
| Up to about 250 lb | Very good | Comfortable seat width |
| 250–300 lb | Good | Within rating; hips may feel snug in the 19.5 in seat |
| Over 300 lb | Not recommended | Above the manufacturer rating |
Room Planning
The space-saving recline means the back does not swing into the wall, but the chair still has a large footprint.
| Check | Requirement |
|---|---|
| Floor width | 35 in for the chair; 48–56 in with side access |
| Floor length, reclined | About 73 in, more with legs extended for tall users |
| Behind chair | About 2 in minimum; 4–6 in is easier for cable access |
| Delivery | Doorways of at least 30–32 in; stairs need two or more people |
| Floor load | About 300 lb plus user on four contact points; use a rug or floor protectors on wood |
| Power | Standard 120 V outlet |
In a 10 x 12 ft living room or bedroom, the M898 can fit in a corner or along a wall, but it will occupy roughly the space of an oversized armchair with an ottoman.
Lower Body Coverage
The M898 does more than typical chairs below the waist. Its SL-track reaches the glutes, the calf section uses rollers that knead and oscillate, and each foot gets shiatsu rollers. People with tight calves from standing jobs or running often value this more than extra back features.
The Tech Features: Useful or Not?
- Voice control: handy for starting and stopping programs without finding the remote.
- Wireless charging pad and USB port: convenient for long sessions.
- Bluetooth speakers and lighting: nice extras but not a reason to choose the chair.
- App control: an alternative to the handheld remote.
These features add points of failure but are not core to the massage. Buyers should focus on fit and the 4D mechanism first.
How It Compares
| Chair type | Height range | Rollers | Typical price |
|---|---|---|---|
| Mid-range 3D SL-track chair | About 5’0″ to 6’2″ | 3D | $2,000–$3,500 |
| Kyota Yutaka M898 | About 5’4″ to 6’7″ | 4D, 49 in SL-track | $3,500–$6,000 |
| Premium dual-track or advanced 4D chairs | Varies, often 5’0″ to 6’5″ | Dual or advanced 4D | $6,000–$12,000+ |
Buying New vs Certified Pre-Owned
The M898 is widely offered as certified pre-owned. That can save a significant amount, but warranty terms are usually shorter and may split coverage between parts, labor and frame. Confirm the exact warranty, ask whether the upholstery was replaced, and check that the remote and all cushions are included.
Pros and Cons
Pros
- Fits users up to about 6’7″ and 300 lb
- 4D rollers on a long 49-inch SL-track
- Strong calf and foot massage
- Space-saving recline with about 2 inches of wall clearance
- 4-year limited warranty on new units
Cons
- Large, heavy footprint
- Seat width can feel snug for users near the weight limit
- Not ideal for users under about 5’4″
- Many tech extras that add complexity
Verdict
The Kyota Yutaka M898 stands out for tall and broad users who are often poorly served by mid-range chairs. Its 4D rollers, long SL-track and thorough lower-body massage justify the price for that group. Shorter users or those with tight spaces should consider a smaller 3D chair instead.
