Massage Chair Comparison: Osaki OS Pro Admiral vs Osaki OS 4000T

Osaki massage chairs are among the most popular brands we offer. Today, we'll be discussing 2 of our most popular models, the OS 4000T and OS Pro Admiral. Both of these chairs are very popular with consumers and we'll take a deeper look at why in this comparison.

A Brief Introduction: Osaki 4000T vs. Pro Admiral

Each of these Osaki chairs offers an impressive range of features. The best-selling S-track Osaki OS 4000T massage chair bases each massage on a computerized body scan, ensuring that your massage is tailored to your body.

With the 4000T you can choose from two pressure-relieving zero-gravity positions. 2D massage rollers and 46 airbags help deliver shiatsu, swedish, tapping, rolling, clapping, kneading, or combo massages, while a heated lumbar region helps you fully relax.

If you're looking for a premium experience, the Osaki OS Pro Admiral massage chair might be more of what you're looking for. This L-track chair features 3D rollers which allows for intensity adjustments. It has 24 airbags and also offers a zero-gravity position.

The Admiral also offers extras like a USB charging port, Bluetooth speakers, multi-language support, and an LCD remote. It's a more expensive chair than the 4000T but if these features are important to you it can be worth it.

Features: A Head-to-Head Comparison

Both the Pro Admiral and the 4000T start your massage with a computerized body scan. The scan helps to better target key muscle groups while avoiding uncomfortable mistakes. But from there, the massage experience is very different.

Now let's take a look at each chair individually and discuss some of their best features.

What are some Top Features of the Osaki OS-Pro Admiral?

Track Type

The Pro Admiral is an L-track massage chair. This type functions similarly, but the L-shaped track extends down to your glutes and hamstrings.

3D Rollers

Both chairs incorporate airbags for a full-body massage. The Osaki Pro Admiral offers 24 airbags. The airbags massage your calves, feet, and arms, and both chairs allow you to adjust airbag intensity.

What are some Top Features of the Osaki OS 4000T?


One of the first things to consider before purchasing a massage chair is the track type you prefer. The 4000T is an S-track chair, which means that the rollers are arranged in a sinusoidal (wave-like) formation.

The S-track formation follows your natural spinal curve and massages from your neck down to your lower back. While the rollers do not extend to hamstrings and glutes, the 4000T uses seat vibration to help relax these areas.

Choose Massage Technique

The ability to choose your massage technique is one of the most exciting things about using a massage chair. The 4000T lets you choose between the following types of massage techniques:

  • Swedish
  • Shiatsu
  • Rolling
  • Kneading
  • Tapping
  • Clapping
  • Combination


The 4000T is a 2D massage chair which is the most common type of massage chair on the market. With a 2D chair, rollers move up, down, left, or right. Though it doesn't feel as close to a massage from a person, the 4000T still delivers a quality massage.

The 4000T also uses two rows of reflexology foot rollers. When used in combination with each chair's foot-level airbags, these rollers help deliver a deep and relaxing foot massage.

46 Airbags

Both chairs incorporate airbags for a full-body massage. The 4000T incorporates 46 airbags. The airbags massage your calves, feet, and arms, and allows you to adjust airbag intensity.

Lumbar Heat

Both massage chairs incorporate heat into your massage for full-body relaxation in the lumbar region.

Additional Features

The Osaki OS 4000T also includes a full-size controller mounted on the chair in addition to a remote.

Both the Pro Admiral and the 4000T are capable of delivering effective and invigorating massages. If you're looking for specialized massage options, the Pro Admiral might be a better fit. Similarly, if you want a chair that can also massage glutes and hamstrings, the Pro Admiral is probably the one for you.

On the other hand, if you don't want to spend the extra money and like what is offered with the 4000T (a lot of people do) then this may be the chair for you.

The choice is ultimately up to you, but it's always best to physically sit in each massage chair and try before buying, if at all possible. We're happy to make recommendations but nothing takes the place of you actually trying out a chair to make sure you like it before purchasing.
