Unique Features Of The Osaki OS 4000 CS

Features Of The Osaki OS 4000 CS

At first glance, it appears that it appears that the Osaki OS 4000 CS Massage Chair seems to be similar to the model OS 4000LS almost. What is the difference between these two models? Find out in the following Osaki OS 4000 CS review.

It’s as simple as that: the OS 4000LS has dual-action foot rollers, whereas the OS 4000CS does not. That’s it.

Other features that are available within OS 4000LS, as well as the other features found on OS 4000LS, besides the foot rollers, can be found within the Osaki OS 4000 CS massage chair.

It includes massage rollers from L-Track with adjustable shoulder massagers spring loaded adjustable ottomans and a recliner that is space-saving, a handheld remote, and a charger for USB.

No Reflexology Foot Massagers

Contrary to those of the OS 4000T and OS 4000LS, the Osaki OS 4000CS does not have massagers that spin in the foot part on the back of the chair. While all the other features of OS 4000CS are similar to those found on OS 4000CS are the same as the features with Osaki 4000LS Osaki 4000LS, users who want to have more support for their feet may be disappointed by the absence of foot massagers that use reflexology on the OS 4000CS a major deal in deciding one of the options.

What The Osaki OS 4000 Massage Chair Is Missing

It’s the Osaki OS 4000 is a top-quality chair packed with options, however, it’s lacking certain features that the more expensive models in the 4000 series have.

Programs And Styles
  • Foot rollers. Although it’s true that the OS 4000 does have a massager for the feet and calf, which includes pressure point nodes it does not have the extra foot rollers some of the other models do.
  • L-Track massage chair rollers. L-track rollers expand the range of massage from the neck up to the buttocks. This model OS 4000 has S-Track massage rollers, but it does not come with massage rollers with L-Track.
  • Space-saving recline technology. The top models of the OS 4000 series utilize a recline track that is space-saving and lets the chair fully recline, with just four inches of room behind the chair. It is the OS 4000, however, requires more space behind the chair in order to recline completely. If you’re limited in space, think about the option of a recliner with space-saving technology.
  • Innovative adjustable shoulder massage. The shoulder massagers on the OS 4000 are set at an unadjustable width, and cannot be adjusted. The shoulder massagers in the OS 4000 should be suitable for the majority of average-sized people however, people with large shoulders might be a bit uncomfortable. If you have large shoulders or prefer more room look into some of the models with adjustable size shoulder massagers.
  • Adjustable spring loaded ottoman. The spring loaded adjustable ottoman – OS 4000 does have an auto leg scan that is customized to fit the foot massager and calf on your leg. It’s not offering the wide length adjustment options that are available by spring-loaded adjustable ottomans that are found on other models of the OS 4000 series.
  • USB charger – In contrast to other Osaki chairs that are available, OS 4000 does not have an inbuilt USB charger. Most people would consider this just a minor drawback and it’s not necessarily a problem.

Is A Preset Deep Tissue Massage Available?

No, Osaki os 4000cs comes without this feature. But you can look for Osaki OS 4000 LS.

It is different from other models such as the OS 4000 and OS 4000T which require users to remain in the manual position as well as in the zero gravity recline position for the benefits of a deep massage, the Osaki OS 4000 LS massage chair includes preset deep tissue massage programs, with no recline required. Let’s talk more about some differences.

Osaki OS 4000CS Vs 4000LS: What’s The Difference?

Osaki OS 4000CS is pretty similar to the exact seat as that of the 4000LS but with one significant distinction:

4000LS Comes With Feet Rollers That Can Be Kneaded, Whereas The 4000CS Don’t

It is the Osaki OS 4000CS massage chair is a different model that uses compressed air to massage your feet. Are foot rollers making all the difference? I’m sure they do!

Air compression massage by itself is not efficient. It’s important to have the right combination of rolling, kneading, and compression massage to maximize the benefits of the massage. Don’t forget the amazing way that the sensation of rolling your feet can be!

If you’re to either purchase the OS 4000CS from Osaki or the 4000LS, I suggest the 4000LS. If you were me I would not even consider the 4000LS, I’d opt for Pro Maxim! Pro Maxim!
