Osaki 4D Helix LE: The Lowest-Priced 4D Pick
The Osaki 4D Helix LE is the lowest-priced chair here and still uses a 4D roller on an SL-Track. Its product page lists three roller intensity settings, a body scan, 22 airbags with five intensity levels, dual-row foot rollers and lumbar heat. It has 15 automatic programs, a two-stage zero gravity recline and an automatic footrest that extends up to 5.7 inches.
Controls and extras
You get a touchscreen tablet, armrest shortcut controls and voice control, plus Bluetooth speakers, wireless charging and a USB-C port. The Helix LE needs about 8 inches from the wall to recline and fits users from 5'0" to 6'1".
Titan Forma 3D+2D: Two Mechanisms for the Money
The Titan Forma 3D+2D is the only dual-mechanism chair in this group. A 3D mechanism works the upper body while a separate 2D mechanism handles the lower back and glutes, on a dual mech SL-Track. It lists 12 automatic programs, 5 manual programs, 26 airbags, foot rollers and heat at the lumbar and calves.
Space and fit
The Forma uses a three-stage space-saving zero gravity recline and needs 6 inches from the wall. Its footrest is spring-loaded and extends up to 7 inches. The product page doesn't list a height range, so check with us if you're on the tall or short end.
Kyota Zenyu M338: Most Programs and the Widest Height Range
The Kyota Zenyu M338 uses a 2D quad-style roller on an SL-Track, so it doesn't offer roller depth adjustment like the 4D chairs. In return, it lists 18 automatic programs, the widest height range here (4'8" to 6'2"), a 300 lb. recommended weight and the longest warranty in the group (4-year limited).
Good to know
It has 14 airbags, a foot roller, lumbar heat, a spring-loaded footrest, Bluetooth speakers and voice control. It needs 9 inches from the wall. If shorter users will share the chair, the Zenyu's 4'8" minimum height stands out.
Titan TP-Epic 4D: Most Airbags and the Tallest Fit
The Titan TP-Epic 4D has the most airbags here (36) and the tallest listed height range (5'0" to 6'4"). Its 4D quad-style rollers offer 5 depth, 4 speed and 3 width settings. It adds calf rollers along with air compression, a three-stage zero gravity recline, an automatic footrest, a touchscreen tablet and voice control.
