What is the weight limit on the Osaki OS-3D Ai Vito?

The published maximum user weight is 260 lbs. That figure is a structural limit for the frame and airbags, not a comfort rating — shoulder and hip width matter just as much for fit.

How much space does the Osaki OS-3D Ai Vito need behind it?

Osaki publishes a 6" wall clearance requirement. Measure from the finished wall — baseboards and outlet covers count against that gap.

What are the dimensions of the Osaki OS-3D Ai Vito?

Upright, the published footprint is 59.4" L x 29.5" W x 44.1" H; fully reclined it measures 69.7" L x 29.5" W x 32.3" H. Check doorways and stair turns before delivery — the chair weighs 174.2 lbs.

Is the Osaki OS-3D Ai Vito a 4D chair?

No. Osaki lists the mechanism as 3D on an SL-track. 3D means adjustable roller depth; check the manual for which speed and rhythm controls this model offers.

Does the Osaki OS-3D Ai Vito have foot rollers, and can they be turned off?

Yes, Osaki lists foot rollers. We have not found a documented on/off or speed control for them in the sources we cite, so check the manual or ask the seller if that matters to you.

Where does the Osaki OS-3D Ai Vito apply heat?

Osaki publishes heat at: lumbar, calves. Other areas are not listed as heated in the sources we cite.

What warranty comes with the Osaki OS-3D Ai Vito?

Osaki publishes: 1 year parts and labor, with 2nd and 3rd year parts coverage. Warranty terms often differ between the manufacturer and individual retailers, so confirm the coverage on the invoice you actually sign.

How much does the Osaki OS-3D Ai Vito cost?

We recorded $1,999 at Osaki USA (direct) on 2026-09-27. Prices change often; confirm the current price and stock with the seller.

Pros

Cheapest 3D Osaki we publish, with SL track, AI body detection and voice control
Lightest chair in our Osaki set at 174 lb, which makes delivery and repositioning easier
Lumbar and calf heat, plus a spring-loaded extendable footrest (7 inches on the product page, 6.5 in Osaki's spec table)

Cons

260 lb user weight limit is the same as the cheaper Champ and 4000XT
Only one year of parts and labor warranty, with extended warranties sold separately
Osaki's own pages disagree on some headline figures (3D vs 4D, 16 vs 24 programs, 44 vs 26 air cells); we use the product-page feature list and flag the rest

Our Take

Our editorial assessment of this chair, based on verified specifications rather than hands-on testing. This is a Research Review.

The OS-3D Ai Vito is Osaki's cheapest published 3D chair and the entry point for adjustable roller depth in the line. On paper it is also the lightest and most compact Osaki we cover: 174 lb, 29.5 inches wide and under 60 inches long upright.

Its biggest strength is the price-to-mechanism ratio. 3D rollers, an SL track, AI body detection, voice control and lumbar plus calf heat are not common at $1,999 from a major brand. Its biggest compromise is durability coverage: the base warranty is one year of parts and labor, with parts-only in years two and three, the same as the OS-4000XT and Champ.

Our editorial assessment: the Vito is the right Osaki for a first-time buyer who wants adjustable depth without paying 4D money. If you will use the chair heavily or share it, the step up to the Dreamer V2 buys more listed air cells (not proof of better compression) and Bluetooth speakers, and the Highpointe 4D a longer warranty.

Where it fits in the Osaki lineup

The Vito anchors the bottom of Osaki's 3D range. It is the chair to look at if adjustable roller depth is the feature you care about most and you want to spend the least to get it.

Same recorded price or less

Osaki OS-ChampAbout $700 less than the OS-3D Ai VitoThe cheapest Osaki we publish — 2D rollers, no published heat therapy, but a 78-inch reclined length.

Higher recorded price

Osaki 3D Dreamer V2About $500 more than the OS-3D Ai VitoMore air cells, a longer reclined length and heated rollers at the lumbar for about $500 more.
Osaki OS-Highpointe 4DAbout $3,000 more than the OS-3D Ai VitoThe cheapest 4D Osaki, with more heat zones, a five-year warranty and only two inches of wall clearance.

What you’re really paying for

Compared with the OS-Champ below it, the Vito premium buys a different mechanism and a more modern control set.

3D + Sonic massage mechanismThe only reason to spend more than the Champ. Adjustable depth changes how the chair feels day to day, especially in a shared household.
AI body detection and automatic body scanOverrated at this priceA positioning aid rather than a massage feature. Useful, but not a substitute for trying the chair's default programs.
Lumbar and calf heatingTwo documented heat zones (lumbar and calves), versus lumbar only on the Dreamer as far as Osaki documents it, and the same count as the Highpointe. A genuine upgrade over the entry models.
Intelligent voice controlOverrated at this priceConvenient if you use it; most users will reach for the touch-pad remote. Not a deciding factor at this price.
Spring-loaded extendable footrestOsaki's product page says 7 inches, its spec table 6.5. Either way it helps taller users, though we have not verified a model-specific height range in the sources checked.

Who it suits, who should skip it

Osaki's most affordable 3D chair and the entry point for adjustable roller depth. Research Review built from Osaki's official product page, with conflicting figures on Osaki's own pages flagged.

Best for: Entry 3D chair with AI body detection and voice control. Skip it if you fall outside the stated fit (Not verified in sources checked, up to 260 lb), cannot give it 6" of wall clearance, or would rather spend less — our budget guides cover cheaper verified chairs.

Buying trade-offs from the published specs

We have not verified a model-specific user height range for the OS-3D Ai Vito in the sources checked. Track length is not a fit rating, so confirm roller reach at the shoulders in person or with the seller before buying.
It needs 6 in. of wall clearance to recline fully.
Its stated user weight limit is 260 lb; 20 chairs we publish list a higher limit.
No 3D chair we publish has a lower recorded price.
Warranty as published: 1 year parts and labor, with 2nd and 3rd year parts coverage. Compare labor, parts and structure tiers separately.

Massage system

Rollers and track: 3D rollers on a SL track. More roller axes add depth and rhythm control; track shape decides how far down the body the rollers travel.

Air, feet and calves: 44 airbags; foot rollers yes, calf rollers not verified. Airbag counts are not comparable across brands without placement data.

Heat, recline and programs: heat at lumbar, calves; 2 zero-gravity position(s); stretch programs not verified; body scanning yes.

We have not measured pressure, noise or heat output on this chair; these figures are the manufacturer's.

Controls and app

Voice control: Yes. Bluetooth: Not verified. Manufacturer app: Not verified.

Warranty, delivery and price

1 year parts and labor, with 2nd and 3rd year parts coverage. Coverage tiers commonly differ between parts, labor and structure, and can vary by retailer.

White glove delivery: Yes. Chair weight: 174.2 lb — measure doorways and stairs before delivery day.
