Osaki OS-4000 and OS-4000T Comparison

We get a lot of calls asking about the differences between the Osaki OS-4000 and OS-4000T, and for good reason. They are very similar. That is why we created this comparison. After reading this, you will have a clearer understanding of the differences between these two models.

What are the Differences between the Osaki OS-4000T and OS-4000?

The Osaki OS-4000 was released over five years ago and has been one of our bestselling massage chairs. Last year, Osaki released the OS-4000T model, which is the upgraded version of the OS-4000. It has all the same great features plus a few upgrades. These include deep kneading foot rollers, better quality synthetic leather, and better quality air compression.

Kneading Foot Rollers

Osaki 4000T Updated Foot Rollers

The biggest upgrade to the Osaki OS-4000T is the Deep Kneading Foot Rollers. These rotate providing a kneading massage to the bottoms of the feet. The Osaki OS-4000 on the other hand, uses acupressure nodes that push up on the bottoms of your feet that squeeze then release. The foot rollers are definitely a big plus and feel great on sore and tired feet.

Upgraded Synthetic Leather

Osaki 4000T Updated Synthetic Leather

The Osaki OS-4000T has upgraded synthetic leather. It’s thicker and more durable then the material used on the OS-4000. The updated material on the OS-4000T definitely looks better when the chairs are side by side.

Updated Air Compression

Osaki 4000T Updated Air Compression

The OS-4000T has an updated air compression system. This is one of the biggest issues with the Osaki OS-4000 model. A lot of users complained about the air compression being too strong and this you may have read in reviews. It’s not an issue with the OS-4000T. They adjusted the PSI, so it doesn’t squeeze too tight on the calves.

Do you have Broad Shoulders?

If you’re thinking about purchasing the Osaki OS-4000T, please keep in mind that the shoulder airbags may be tight on some users. If you are taller than 6’3” or have broad shoulders (wider then a men’s 46 jacket size) you may want to consider a massage chair with more shoulder room.

We would recommend looking at the Osaki OS-4000LS, Osaki OS-7200H, OsakiOS-3D Pro Dreamer, or Ogawa Active SuperTrac. These all have more shoulder room and would be a much better fit.

      Between the Osaki OS-4000 or Osaki OS-4000T, both would probably be too small for you. The massage roller would not be able to reach high enough and you may have issues in with the calf massager for fit. We would recommend the Luraco Massage Chairs. They are the only massage chair designed, engineered, and built in the USA, so they are made for the American market. Most of the massage chairs on the market have been designed for the Asian markets.

    Would either the Osaki OS04000 or the Osaki OS-4000T be acceptable for a 6’3 235# man? I see conflicting comments about this.

      Hi Richard
      Great question. Here is our recommendation. “If you’re thinking about purchasing the Osaki OS-4000T, please keep in mind that the shoulder airbags may be tight on some users. If you are taller than 6’3” or have broader shoulders (a jacket size bigger than 46″-48″) you may want to consider one of Osaki’s other models that have more shoulder room.”

      The OS-4000 has about 20 inches from shoulder to shoulder, so it most likely would be a tight fit for you – especially when the shoulder airbags inflate.

      We would recommend looking at the Osaki OS-7200H and the Osaki OS-3D Pro Dreamer. These have about 3″ total more shoulder room, which would be a more comfortable fit.

      If you would like to stay around the $2000 price point, the Ogawa Refresh is a great choice and has flared out shoulder airbags. These would be a better fit since they don’t wrap around the shoulders. It also has a deeper neck massage then the Osaki OS-4000T.

      We have some great New Year Specials that are better than the discounts on the website. Just contact us at 888.360.0006, or Ask an Expert, or just Live chat us and let us know the model your looking at, and we will let you know if we have any additional specials. Please let us know if you have any additional questions.

      Yes, both the Osaki OS-4000 and the OS-4000T have lumbar heat. The OS-4000T is the newer model and comes equipped with foot rollers.
