The Osaki OS-4000 is a higher end luxury massage chair for the discerning buyer. While it’s not the most expensive electric massage chair out there, it’s certainly not the cheapest, costing double or three times as much as budget models.
That said, if you’re a buyer who prioritizes comfort and relaxation, you may find that your expenditure is rewarded when it comes to this model from Osaki. While it’s certainly premium, it doesn’t have any specific, standout features or settings that might make you want to choose it over any other expensive chair for its functionality. Despite that, there is one simple reason we can recommend this chair to anybody: it’s incredibly comfortable, even for a massage chair.

The chair is characterized by plush cushions that surround every part of the user’s body, from head to toe. (Literally. There are foot rests.) If you’re willing to trade the higher functionality you might find in a comparable chair for a little more comfort and easy relaxation, then the Osaki OS-4000 is the chair for you.
Like comparable premium offerings, this massage chair from Osaki features a body scan system, meaning it can match itself to your body’s proportions. It’s a great feature for anybody who loves massage chairs, but often feels like their body doesn’t quite fit the targeted massage areas in exactly the way they want to every time. That scanning technology extends to the legs as well, unlike the partial system found in other chairs, so you don’t have to worry about only getting a good massage on your back.
In addition, there are five separate speed and intensity levels for each massage setting, a seat vibration massage, and lower back heat therapy available, all of which can be controlled using a large and accessible-friendly remote. It’s worth noting that in this chair, the heat therapy only extends to the lower back; you won’t necessarily be able to get heat therapy on your arms or calves.
The ergonomic, S-track massage system works in combination with a plethora of airbags that provide pressure on the arms, feet, calves, hips, lower back and shoulders for a full-body experience.
As it states in the chair’s title, this is a zero-gravity model. That means it can take you to full horizontal, and you can lie down completely while experiencing the massage, rather than having to sit up or to stay in a suspended, halfway state.
The Osaki OS-4000 features a range of both manual and auto massage techniques, including kneading, tapping, clapping, Shiatsu, rolling, combination and Swedish style massages.
This chair’s quality falls squarely in the middle-to-high tier of massage chairs. It’s certainly a premium option, and the chair’s price reflects that, but this isn’t even close to the most expensive chair you could buy. There are options costing two or three times as more out there. That makes the Osaki OS-4000 a good option for users who have a little more purchasing power, but don’t want to go too crazy with splurging on a new massage chair.
This chair is made of synthetic leather rather than real leather. You may feel that, for the price, it’s not justifiable to invest in a synthetic leather chair. However, the Osaki is veritably comfortable despite the fact that it’s synthetic leather. It also comes with a 3-year warranty for all parts, so you don’t have to worry about the synthetic covering on the durability front.
Moreover, even though a connoisseur may be able to tell that it’s synthetic, we would argue that this chair’s synthetic leather is good enough that the average user wouldn’t be able to discern the difference. And what really matters here is simply that it’s comfortable, not whether or not the chair’s covering came from a real animal. And comfort is something the Osaki-4000 has in spades.
So with that in mind, we still recommend the Osaki chair, as the synthetic leather material is more than up to snuff. However, if heaving real leather is high on your list of priorities, you’ll need to look elsewhere.
Pros and Cons
- Very comfortable
- Mid-range premium. It’s still accessible, but definitely on a higher tier than budget or middle-of-the-road chairs.
- Zero gravity mode is legitimately relaxing
- Features a very reasonable selection of different massage modes to choose from, including both Shiatsu and Swedish
- Covering is made of synthetic rather than real leather, which is definitely a hit in this price range
Overall, the Osaki OS-4000 prioritizes comfort despite its synthetic leather covering. As far as massage chairs go, this is a pretty high-end model, but it’s not the absolute most luxurious. That puts it in a good category for buyers who want something slightly better than average, but who don’t want to spend too much for the privilege.
