Osaki OS 4000T Massage Chair Review

Osaki OS 4000T Massage Chair Review

The Osaki OS 4000T isn't the most technologically advanced chair, but it comes with unique features that even more advanced chairs don't have. For example, most chairs come with small remotes—some easy to use, others more complicated.

The Osaki OS 4000T comes with a wireless remote, but it also has a full-size control panel attached to the front of the chair. In this Osaki OS 4000T massage chair review, you're going to learn why this chair is a customer favorite.

The Osaki OS 4000T comes with a whopping forty-six airbags that massage your arms, calves, feet, and other parts of your body that the rollers can't reach.

Other unique features include the leg scanner, two zero gravity modes, seat vibration, and heated lumbar function. You'll even get five different automatic programs. If you're in the market for a new massage chair, this Osaki OS 4000T review offers a closer look at what this chair has to offer.

Top Features of the Osaki OS 4000T Massage Chair

The Osaki OS 4000T is packed with features that make it worth your time and money. Here are some of the top features of the Osaki OS 4000T massage chair.

Two Zero Gravity Modes

Zero gravity mode is one of the most popular features in the massage chair industry. Unfortunately, it usually only has one option, and if you don't like that position, there's not much you can do about it.

Osaki OS 4000T Two Zero Gravity Modes

The OS 4000T from Osaki comes with two zero gravity modes that offer different levels of recline so you can enjoy your massage the way you want to.

Seat Vibration

The Osaki OS 4000T comes with a seat vibration function that makes your massage even more relaxing. You can turn this function on or off depending on how you're feeling at the time.

Leg Scanners

When you sit down in this chair, you'll place your feet in the footrests so you can enjoy a calf and foot massage. Of course, not everyone's legs are the same length.

The Osaki OS 4000T extends the footrest before your session, then slowly retracts until you tell the chair to stop.

Multiple Control Options

One of the most striking features of the Osaki OS 4000T is the full-size control panel attached directly to the chair. You can press the buttons to adjust the settings and choose your massage program.

If you don't like using the control panel, the Osaki OS 4000T also comes with a wireless remote that's easy to use.

Four Color Options

The Osaki OS 4000T has four different color options ranging from taupe to charcoal. This is ideal when you're trying to find the best color to go along with your existing decor.

Airbag Massage Functions

With forty-six strategically placed airbags, the Osaki OS 4000T can massage your calves, feet, arms, shoulders, hips, and lower back. This allows the chair to massage parts of your body that the rollers might not be able to reach.

The Osaki OS 4000T is a nice chair for the money. It does lack in certain areas like space-saving technology and Bluetooth speakers, which might be a dealbreaker for some customers.

However, you won't find many chairs that come with a full control panel and a whopping forty-six airbags. This chair also has a unique design and multiple color options with coordinated color palettes.

The 2D rollers are a little low-tech, but you can still enjoy a compression massage and a heated lumbar area. Plus, you can choose from two zero gravity modes—one has a near flat recline while the other is a little more upright.

The Osaki 4000T massage chair isn't a new chair and has been around for awhile. With that being said, this has been one of our best-selling massage chairs, it's priced right and packed full of useful features.
