Osaki | Ai Apex Duo 5D+4D

Osaki Ai Apex Duo 5D+4D Massage Chair

The Osaki Ai Apex Duo 5D+4D is a massage chair that runs two roller units at once, a 5D unit on your neck, shoulders and back and a 4D unit on your glutes and hamstrings. 4D means the rollers vary depth, speed and rhythm as they travel, and 5D adds one more movement, here the heads travelling with you as you shift. A live time body scan reads your position and moves them through the session, so neither unit leaves its station and one program covers your whole back and seat. It comes in Black, Brown and Taupe with a 5-year warranty.

Underneath the two mechanisms sit 46 auto programs, with 5 manual modes and five levels each of intensity, speed and pressure. Forty-six is the largest auto library on any Osaki chair. Sixty-two air cells wrap the chair for a full body air massage. The arm and palm bags are split into three segments that inflate in sequence down the length of your forearm. Heat runs in three zones at once, at your lumbar, both calves and both feet. Both side panels slide back at the press of a button, so you step in at seat height. Zero gravity is the recline that raises your knees over your heart and takes your weight off your spine. Micro space saving carries the Apex Duo into a full three-stage version of it with 1 in. of clearance behind. An armrest sensor reads blood oxygen and heart rate, and feeds the reading into the program the chair selects. The numbers show on an 8 in. touchscreen that also pulls new programs over Wi-Fi. Smart Pressure Sensors read the load under each head and adjust it mid-program. The Apex Duo weighs 332.3 lb, takes a user up to 280 lb and 6 ft 3 in., and comes in Black, Brown and Taupe.

Inside the chair

How it works

The Apex Duo places pressure with a 5D upper mechanism over a 4D lower one, a body scan that keeps running while the massage runs, an armrest sensor that reads blood oxygen and heart rate, and an SL-Track that carries both units from your neck to your hamstrings.

A 5D Unit Over a 4D Unit

The upper mechanism is 5D and works your neck, shoulders and back. The lower mechanism is 4D and holds your glutes and the top of your hamstrings. Both run at the same time, so a single auto program covers your neck, your back, your glutes and your hamstrings without either unit leaving its station. Osaki build dual mechanism chairs pairing 4D with 3D and 4D with 4D as well, and 5D over 4D is the highest pairing in the range.

5D over 4D

Live Time Body Scan

The body scan on the Apex Duo carries on after the program has started. It keeps reading your position through the session and moves the massage heads with you. The heads hold the same points along your back once you have settled in, shifted your weight or dropped the recline another stage. Smart Pressure Sensors ride with the heads and trim the firmness as your position changes.

Runs all session

AI Health Detection

A sensor at the armrest reads blood oxygen and heart rate while you sit. Those readings go to the 8 in. touchscreen, which keeps them on display, and into the program the chair picks out of its 46. The sensor is what turns the largest program library Osaki build into a single press. The Apex Duo is a consumer massage chair and the reading is not a diagnosis.

Blood oxygen, heart rate

Ergonomic SL-Track

The SL-track is the one rail both roller units ride, curving from your neck and shoulders through the lower back and down to your glutes and the top of your hamstrings. It carries on past the point where your spine meets the seat, so a stroke that starts at your neck finishes on the back of your thighs. An S-track is the shorter rail that stops at the lower back and leaves your glutes and hamstrings to the airbags.

Air

Sixty-Two Cells and a Three-Segment Armrest

Sixty-two air cells cover the parts of your body the two roller units cannot reach, built in multiple layers so the compression arrives across a zone in stages. The arm and palm bags are split into three segments that inflate in sequence, so the squeeze travels down your forearm to the wrist and then the hand as a wave. Below the seat, the calf rest works in an outer rotation kneading motion using 8 airbags and 2 rollers. Each foot gets 4 rollers and 16 airbags, covering the soles, the sides, the backs of the feet and the Achilles tendon. Between the 5D unit on your back, the 4D unit on your glutes and 62 cells around the rest of you, one program reaches from your neck to your toes.

Heat and fit

The Heat Switches Separately From the Massage

Heat reaches three zones on the Apex Duo at the same time: your lumbar, both calves and both feet. The footrest sitting under those calves extends automatically by up to 7 in. to meet the length of your leg, and that travel lets the chair fit a 6 ft 3 in. user. The heat is switched separately from the massage, so you can run any of the 46 auto programs with the three zones on or off. Maximum user weight is 280 lb, and the same footrest travel closes the gap for a shorter user so the sole still meets the foot rollers.

Position

There Is No Arm to Climb Over

Both side panels slide back on a rail at the press of a button, so the way into the chair is level with the seat and there is no arm to climb over. Micro space saving handles the other end of the room problem. The seat slides forward as the backrest drops, so the Apex Duo reaches a full three-stage zero gravity recline with 1 in. of clearance behind it. Upright it measures 33.5 in. wide by 65.7 in. long by 48.5 in. tall, and reclined it measures 33.5 in. by 70.9 in. by 34.6 in. Width holds at 33.5 in. in both positions, so that is the number your doorway has to clear, or 30 in. with the chair taken apart.

Questions

Frequently asked questions

Two roller units, working at the same time. The upper unit is 5D and covers your neck, shoulders and back. The lower unit is 4D and covers your glutes and hamstrings. On a chair with a single roller carriage the top of your back and your hamstrings take turns, one waiting while the other is worked.

The heads travelling with you. A 4D mechanism varies depth, speed and rhythm as it moves along the track. The 5D upper unit adds one more movement on top: the heads follow you around the seat while the program runs. A live time body scan carries on reading your position after the program has started and keeps them on the same points. Smart Pressure Sensors handle the other half, adjusting the load under each head as the program runs. The other 5D chair in the Osaki range is the Osaki 5D+4D Kairos Duo, and it spends its fifth movement on something else. There the extra movement is reach, taking the heads further out of the backrest than a 4D roller travels. Same badge on two chairs, two different fifth movements, so compare them on what the movement does and not on the number.

46 auto programs and 5 manual modes, the largest auto library on any Osaki chair. For comparison, the Osaki Grand Duo 4D+4D carries 41 and the Osaki 4D Orion Duo Mech carries 16. The 5 manual modes are Kneading, Tapping, Knocking, Shiatsu, which is the pressing-and-holding one, and Kneading & Tapping.

Blood oxygen and heart rate, read at the armrest while you sit. The readings appear on the 8 in. touchscreen and feed the program the chair selects from its 46, which is how a library that size gets used without scrolling every title. The chair is a consumer massage chair and the reading is not a diagnosis.

Both side panels slide back on a rail at the press of a button, on the left and the right. The opening ends up level with the seat, so you sit down and swing your legs across with no armrest to climb over, and the panels take no extra floor space to open.

Three zones at once: the lumbar, both calves and both feet. The heat switches separately from the massage, so it runs under any of the 46 auto programs or on its own.

The calf rest uses an outer rotation kneading motion with 8 airbags and 2 rollers. Each foot gets 4 rollers and 16 airbags, covering the soles, the sides, the backs of the feet and the Achilles tendon. Heat runs through both the calf and the foot section.

Maximum user weight is 280 lb and the chair fits a user up to 6 ft 3 in. The footrest extends automatically by up to 7 in. to reach the length of your leg, and the travel is driven from the touchscreen. Two people of different heights can share the chair without either of them sitting at the wrong length. Shoulder width is 24.5 in. and seat width is 21.0 in.

1 in. Micro space saving slides the seat forward as the backrest drops, so the chair reaches a full three-stage zero gravity recline an inch off the wall. Upright it is 33.5 in. W x 65.7 in. L x 48.5 in. H, and reclined it is 33.5 in. W x 70.9 in. L x 34.6 in. H, so allow about 71 in. of length for the reclined footprint.

Plan on 33.5 in. assembled, the same as the chair's width, or 30 in. disassembled. Measure the whole route while the tape is out. The narrow point on a delivery is usually a stair turn or a hallway corner and not the door frame itself.

The assembled chair weighs 332.3 lb, and it arrives in two crates whose packed weights are higher again. Crate one is 33.5 in. x 51.4 in. x 50.2 in. and 340.6 lb on the truck, crate two is 16.9 in. x 41.8 in. x 29.6 in. and 56 lb. Book the freight and walk the delivery route before the chair arrives, because 340.6 lb does not go round a stair turn on its own.

Five levels each of intensity, speed and pressure, on top of the 5 manual modes. Controls run through the 8 in. touchscreen, which updates its programs over Wi-Fi, and through hands-free voice commands on the preset command list.

Aromatherapy, a negative ionizer that is the cabin's small air-treatment unit, and chromotherapy LED lighting that is the colored mood light. Bluetooth speakers, a wireless charging surface and a USB port sit alongside them. It runs off a normal wall outlet, 110 to 120 V at 50/60 Hz.

Black, Brown and Taupe, three covers over the same chair. The Apex Duo carries a 5-year warranty, made up of 3 years full service plus a further 2 years on parts.
