DETAILED OVERVIEW
The Yutaka M898 is the most comprehensively documented premium chair in this catalog. Its 4D mechanism varies depth and speed along a 49-inch L-track, and Kyota publishes a 5′4″–6′7″ optimal range, 300-pound maximum, 2-inch wall clearance, and four-year limited residential warranty.
The chair also includes 12 automatic programs, 24 airbags with 56 cells, triple sole rollers, calf kneading and oscillation, three zero-gravity levels, lumbar heat, body scanning, mechanical foot adjustment, app and voice controls, Bluetooth, USB, and wireless charging.
WHO IT SUITS
FEATURE ANALYSIS
Kyota’s 4D system moves up/down, side-to-side, and in/out, then varies speed to change the rhythm. The 49-inch L-track extends the roller path from the back toward the glutes.
Three rollers work each sole while the calf unit adds mechanical kneading and oscillation. Mechanical foot adjustment helps accommodate the published height range.
FIT AND ROOM PLANNING
The 5′4″–6′7″ optimal range is the strongest tall-user documentation in this catalog. The 35-inch width and 300-pound maximum still need to be checked independently; a tall user above the weight limit is not a supported fit.
Space-saving recline reduces the rear gap to 2 inches, but the full chair still reaches 73 inches long and 35 inches wide. At 304 pounds net and 367 pounds gross, professional delivery planning is appropriate.
