Osaki | 5D+4D Kairos Duo

Osaki 5D+4D Kairos Duo Massage Chair

The Osaki 5D+4D Kairos Duo is a massage chair that runs a 5D hand on your back and a 4D unit on your glutes and hamstrings. A 4D roller pushes out of the backrest and back in, and changes speed as it presses. A 5D unit is a 4D one with a further movement layered on top. Here that movement is extra reach out of the backrest. Smart Pressure Sensors set how firmly each head presses as it travels. The heads on that upper unit carry heat. The 4D unit holds its station under the seat. One program covers your neck and your hamstrings in the same minute.

Around the two mechanisms sit 56 air cells for a full body air massage. An air cell is the inflatable bladder that squeezes a limb and lets go. Calf rollers and a calf kneading function work the lower legs. Reflexology is the word for pressure on specific points of the sole, and 2 foot rollers per foot run it from your toes to your heels. The track is laser-crafted steel in the SL shape, and it carries the rollers from your neck and shoulders to the top of your hamstrings without a break at the hips. Heat runs in the massage heads, in a shawl you can lift out and drape where you like, and at the calves, at roughly 75 to 83 degrees F. Twenty auto programs sit over 5 manual modes, with five levels each of intensity, speed and pressure. You drive all of it from a touchscreen or by voice with Hello Osaki. The chair reclines fully with 1 in. of clearance behind it and takes a user up to 280 lb. It weighs 284.0 lb and comes in Black, Brown and Taupe.

Inside the chair

Where the Fifth Axis Sits on the Kairos Duo

A 5D upper hand over a 4D lower mechanism, sensors that set the pressure for you, heat carried in three places including the massage heads, and a laser-crafted steel SL-track underneath all of it.

A 5D Upper Over a 4D Lower
The upper massage hand is 5D and works your neck, shoulders and back. The lower mechanism is 4D and works your glutes and hamstrings. Both run at the same time, so a program covers the top and the bottom of your body together. The fifth movement on the upper hand is reach: it travels further out of the backrest than a 4D roller does, and the heads on that unit are heated.
5D over 4D
Smart Pressure Sensors
Smart Pressure Sensors read how you have settled into the seat and how you move once the program is running, and they aim the heads at the pressure points along your back. They also set how firmly each head presses, so the chair decides the pressure through the session and you are not stuck with the level you picked at the start.
Sets its own pressure
Heat in Three Places
The Kairos Duo carries heat in three places: the massage heads themselves, a shawl you can lift out and drape wherever you want it, and the calves. All three run at roughly 75 to 83 degrees F. Heat in the heads travels with the rollers down the track, so the warm surface moves with the massage, and a fixed pad behind your lower back cannot follow it that way.
75 to 83 degrees F
A Single Steel Rail From Neck to Hamstrings
The SL-track is the single continuous rail that carries the rollers from your neck and shoulders, through the lower back, and down to the top of your hamstrings. The rail is cut from laser-crafted steel and there is no break at the hips. An S-track is the shorter shape, and it ends where your spine meets the seat.

Mechanism

The Body Scan Runs at Every Power-On

Every time the Kairos Duo powers on it runs a full body scan, reading the contours and the dimensions of your back and fitting the roller placement to them. The scan keeps working while the program runs and re-adjusts as you change position, so the placement it found at the start does not go stale halfway through a session. Above and below that scan sit the two mechanisms: the 5D upper hand on your neck, shoulders and back, and the 4D lower mechanism on your glutes and hamstrings, both moving at once. Smart Pressure Sensors sit across the pair and decide how firmly each head presses at the point it has reached.

  • Full body scan on every power-on
  • Scan re-adjusts in real time as you move
  • 5D upper hand with heated massage heads
  • 4D lower mechanism on the glutes and hamstrings
  • Smart Pressure Sensors set the pressure

Air and lower leg

Fifty-Six Air Cells and Reflexology Underfoot

The roller track is the rail the two mechanisms travel along, and 56 air cells reach the parts of you it cannot. They inflate and release in sequence around your arms, hips, legs and feet while the mechanisms work the center line of your body. At the bottom of the chair the hardware changes. Rollers in the calf section knead the lower legs. Two foot rollers with reflexology ridges sit under each sole, covering the length of the foot from the toes to the heels. Calf heat runs through the same section, so the lower leg gets air, rollers and warmth inside one program.

  • 56 air cells across the arms, hips, legs and feet
  • Calf rollers plus a calf kneading function
  • 2 reflexology foot rollers per foot, toes to heels
  • Calf heating at roughly 75 to 83 degrees F

Position

Three Recline Positions and an Inch of Wall

Space-saving is the frame sliding forward as the backrest goes down, so the Kairos Duo reaches a full recline with 1 in. of clearance behind it. It can sit against a bedroom wall. Three recline positions are stored. Zero gravity is the recline that lifts your knees above your heart so your weight comes off your spine, and Leisure and Sleep sit beside it. Upright the chair measures 33.0 in. wide by 62.0 in. long by 47.5 in. tall. Reclined it measures 33.0 in. by 70.0 in. by 36.5 in. Width holds at 33.0 in. in both positions, which is also the doorway figure to measure against. The removable headrest comes out if you want the top of the backrest clear.

  • 1 in. of wall clearance at full recline
  • Zero gravity, Leisure and Sleep positions
  • Upright 33.0 in. W x 62.0 in. L x 47.5 in. H
  • Reclined 33.0 in. W x 70.0 in. L x 36.5 in. H
  • Minimum door width 33.0 in.

Four Osaki Dual Mechanism Chairs

All four hold one roller unit on your back and a second on your lower body, both working at once. The Kairos Duo and the Ai Apex Duo are the two 5D chairs of the group, and the fifth movement is a different thing on each. On the Kairos Duo it is reach, travelling further out of the backrest than a 4D roller does, with Smart Pressure Sensors setting the pressure and heat built into the massage heads. On the Apex Duo it is the heads moving with you, kept on target by a body scan that never stops running.

Questions

Fourteen Questions Before the Kairos Duo Arrives

It runs two massage systems at once, an upper hand for your neck, shoulders and back and a lower mechanism for your glutes and hamstrings. A single mechanism chair has one roller unit that travels the whole track, so it reaches one area at a time. The Kairos Duo keeps a unit stationed at each end and works both halves of your body together.
The upper hand is a 5D mechanism, and its fifth movement is reach: it travels further out of the backrest than a 4D roller does. Smart Pressure Sensors decide how firmly it presses as it travels, reading how you have settled and how you move, and the heads on that unit are heated. The lower mechanism stays 4D.
Both pair a 5D upper mechanism with a 4D lower one, and the fifth movement is a different thing on each chair. On the Kairos Duo it is reach past what a 4D roller travels, with Smart Pressure Sensors setting how firmly the heads press and heat built into the heads themselves. On the Osaki Ai Apex Duo 5D+4D it is the heads moving with you, held on target by a live time body scan that keeps reading after the program has started. The Apex Duo also carries 62 air cells and 46 auto programs against 56 air cells and 20 auto programs here. Both chairs recline fully 1 in. from a wall and take a user up to 280 lb.
Three places: the massage heads on the upper mechanism, a drapeable shawl you can lift out and lay where you want it, and the calves. All of it runs at roughly 75 to 83 degrees F. Heat in the heads travels with the rollers down the track, which is a different placement from a fixed pad behind the lower back.
Calf rollers with a calf kneading function work the lower legs, and 2 reflexology foot rollers per foot cover the soles from the toes to the heels. Calf heating runs through the same section, and part of the 56 air cell count sits around the legs and feet.
56, wrapping your arms, hips, legs and feet for a full body air massage. That sits between the 38 cells on the Osaki 4D Bravo Duo Mech and the 62 cells on the Osaki Grand Duo 4D+4D.
1 in. Space-saving technology slides the seat forward as the backrest goes down, so the chair reaches a full recline an inch off the wall. Upright it is 33.0 in. W x 62.0 in. L x 47.5 in. H, and reclined it is 33.0 in. W x 70.0 in. L x 36.5 in. H, so allow about 70 in. of floor length and you are covered in either position.
Plan on 33.0 in., the same as the chair's width in either position. Measure the whole route while the tape is out, because stair turns and hallway corners stop more deliveries than door frames do.
Seat width is 20.5 in. and shoulder width is 20.0 in., with a maximum user weight of 280 lb. Measure your own seated hip width against the 20.5 in. figure, because seat width decides the fit of a massage chair as much as the weight rating does.
The chair weighs 284.0 lb and arrives in two boxes. Box one is 31.69 in. x 58.46 in. x 37.99 in. at 298.0 lb, and box two is 16.73 in. x 39.96 in. x 24.41 in. at 39.0 lb. Book the freight and walk the route through the house before delivery day.
20 auto programs, among them Sports Recovery, Stretch and Spine Care, plus 5 manual modes: Knead, Knock, Tap, Knead & Tap and Shiatsu, which is the pressing-and-holding one. On top of those you set five levels each of intensity, speed and pressure.
A touchscreen controller runs the chair, and voice control answers to Hello Osaki and Hi Osaki on the preset command list. The headrest is removable if you want the top of the backrest clear.
A negative air ionizer is the small air-treatment unit built into the cabin, and beside it sit Bluetooth speakers, a wireless charging surface and a USB Type-A port. Three recline positions are stored as well: zero gravity, Leisure and Sleep. The chair runs on a standard household supply, 110 to 120 V at 50/60 Hz.
Three colors: Black, Brown and Taupe. Same chair underneath all three, with the same 5D upper mechanism, the same 56 air cells and the same 1 in. wall clearance. The Kairos Duo carries a 5-year warranty, made up of 3 years full service plus a further 2 years on parts.
