The Osaki Emperor II 4D packs a 4D mechanism, an SL-track that reaches your glutes and a zero-gravity recline into one massage chair. It makes most sense for people who want a full-length back massage with their legs up; we rate it 5.8/10 from its listing.

16 auto programs

That many ready-made sessions are named in the listing. Press one, lean back, and you never have to build a massage by hand.

What it has going for it

What changes in your evenings

4D rollers. On top of 3D depth control, the rollers vary their speed and rhythm as they work.

SL-track. The rollers follow your spine and keep going under the seat.

Zero-gravity recline. Lean back until your legs rise to about the level of your heart, then let the program run.

Living room or bedroom?

In the living room, the Bluetooth speakers turn it into the spot for music or a podcast, not just a massage. The body scan sets it up again for whoever sits down, handy when the whole household shares it.

In the bedroom, the space-saving design sits closer to the wall, which matters in a smaller room. Heat plus 16 auto programs make an easy wind-down before bed: pick one and lie back. Voice control means no hunting for the remote with the lights off.

On paper it leans toward the bedroom.

Great for you if…

You like a roller massage that changes pace instead of repeating one stroke
You carry tension low down and want the rollers to reach your hips and glutes
You want to lie back with your legs raised after a long day

Skip it if…

Living with it

Delivery day

The listing gives no weight for the Osaki Emperor II 4D, so ask before delivery day and line up a second pair of hands. Check the manual for how much assembly is left to you.

Finding its spot

It is sold as space-saving, so it can sit closer to the wall than most. Still measure the full recline: "space-saving" is not a number. Our fit planner checks it in a minute.

Your evenings

Lean back into zero gravity, pick one of its 16 auto programs and let the heat warm your back.

Fit, setup and support

What the Osaki Emperor II 4D listing names:

SL-track
4D roller mechanism
Zero-gravity recline
16 auto programs
Foot rollers
Calf massage
Body scan
Bluetooth speakers
Voice control

Hold the height range, the weight limit and the full-recline depth against your home before you order.

The one thing we'd check first

If we were buying the Osaki Emperor II 4D, we'd check the gap to the wall first: space-saving chairs still need some clearance behind the backrest, and the manual gives the figure.

Before you buy

Your room

Measure the full-recline depth and the gap to the wall; the listing says space-saving, but confirm the clearance in the manual. Our fit planner runs the check in a minute.

Your body

Confirm the user height range and the weight limit with the seller or in the manual, for everyone who will use the chair.

Delivery

Measure doorways, stairs and turns, and check whether delivery stops at the curb or comes into the room.

Warranty

Ask what the warranty covers (frame, motors, upholstery), for how long, and who handles repairs.

Price and availability

On Sep 30, 2026 the listing showed $4,999. That puts it in the pricier third of the 67 massage chairs we have a recent price for.

Our take

The verdict

5.8Fair · out of 10

What we'd buy the Osaki Emperor II 4D for is a 4D mechanism, with an SL-track that reaches your glutes as a bonus. Nobody has posted a buyer review we could count yet, so the listing is all we have to go on. Where it falls short: no word on the weight limit or the warranty. We'd pick it if you like a roller massage that changes pace instead of repeating one stroke; otherwise, put it next to the Real Relax PS6500 4D first.

Frequently asked questions

Is the Osaki Emperor II 4D any good?

We rate it 5.8/10 (fair). The rating comes from its documented listing alone, as no customer-review record is captured yet.

What do you get with the Osaki Emperor II 4D?

Its listing states a 4D mechanism, an SL-track that reaches your glutes, a zero-gravity recline, foot rollers for the soles, a body scan and calf massage. These are the seller's figures, not our measurements: how the massage feels can't be read from a listing.

What should I check before ordering the Osaki Emperor II 4D?

Your room: measure the full-recline depth and the gap to the wall; the listing says space-saving, but confirm the clearance in the manual. Our fit planner runs the check in a minute. Your body: confirm the user height range and the weight limit with the seller or in the manual, for everyone who will use the chair. Delivery: measure doorways, stairs and turns, and check whether delivery stops at the curb or comes into the room. Warranty: ask what the warranty covers (frame, motors, upholstery), for how long, and who handles repairs.

Where can I buy the Osaki Emperor II 4D?

We link to the exact listing on Amazon, where today's price, stock and seller apply. It is an affiliate link, and it has no effect on the rating.

Have you used the Osaki Emperor II 4D yourselves?

No, we haven't used it ourselves. Everything on this page comes from its listing, read line by line and weighed with our published formula.
