Deep Tissue Massage Comparison
Massage has been proven to bring great benefits both for pain management, tension release and relaxation. According to an article published by the National Center for Biotechnology Information, NCBI, massage is touted to provide more help in pain management when compared to no pain treatment option.
Deep tissue massage involves the application of sustained pressure using deep slow strokes to target inner layer of muscles and connective tissues. Osaki-OS 4000 and 4000T models do not provide deep tissue massage, a very important feature for anyone who suffers from deep muscular injury that requires treatment.
This feature is only provided by the 4000CS and LS models. The Osaki 4000CS and LS models offers this function through the use of its Deep Tissue Massage auto program.
With that preset auto program you are availed of a hard massage that targets troubled spots to relieve chronic pain.
Roller Track Type Comparison
There are two basic roller track types that are deployed by the Osaki-OS 4000 models, the S-track and the L-track. The S-track type while ergonomically designed to mimic the sinusoidal curve of the spine, is limited in its use.
It massages from the neck down to the lower back but excludes the buttocks and thighs. A needed feature if you suffer from muscular pain in your thighs.
The L-track roller type however extends beyond the back to buttocks and thighs hence providing you with a more encompassing massage.
Osaki 4000 and 4000T features S-track rollers while the Osaki 4000CS and LS features the L-track rollers. The roller track guides the quad rollers which mimic human thumb along the track to carry out the massage function.
The longer the roller length the more areas it can cover per use and run. The Osaki-OS 4000 and 4000T features a roller length of 30’’ while the 4000 LS and CS features 42”; this of course is because the former have an S-Track while the latter have the L-track.
Glute massage occurs when the rollers extend beyond the back down to the buttocks and thighs as explained above. Because the Osaki 4000 and 4000T models do not have the L-track roller tack it cannot perform this function.
Osaki 4000 and 4000T models using its manual programs can deploy massage techniques such as Rolling , Kneading, Swedish, Clapping, Shiatsu and a Combo any of these techniques. While the remaining models 4000CS and 4000LS deploy the following massage styles Tapping, Kneading, Shiatsu and Combo.
It’s very important to note that the Osaki-OS 4000 CS and LS do not offer Swedish style of massage a direct opposite of the deep tissue massage that it offers.
The intensity of the rollers that provide all these massage styles can be adjusted for each model except for Model 4000LS. A key function that differentiates it from the rest.
I find that I often suffer from tired feet whenever I am so busy that I hardly have the time to sit and relax. Reflexology alleviates this pain.
Osaki-OS 4000, 4000T, 4000LS all come equipped with rollers that combine with the airbags attached to provide a pin point acupressure that helps to relieve tired feet.
Unfortunately, the Osaki-OS 4000 CS does not offer this feature. If reflexology is an important feature for you, cross that one off the list.
Adjustable Shoulder Length
The Osaki 4000 and 4000T models had an issue for people with narrow shoulders. With the Osaki-OS 4000CS and LS models, a 3 phase adjustability option was provided.
Space Saving Technology
When you recline on the 4000CS and LS models, there is a double adjustability with the recline backwards and the elongation of the seat, hence saving you space.
This model requires about 4 inches backwards to be fully extendable. Osaki 4000 and 4000Tdo not have the space saving technology. Like most massage chairs, it requires about 2 feet of space.
Recommended Height And Weight
The added advantage 4000CS and LS models the fact that weight range reaches up to 285 Lbs, a 20 pounds increase from the Osaki 4000 and 4000T models. Both chair work well for taller people up to 6’4”.
Control functions are usually an issue with massage chairs, I would want a remote that is easy to use and can be easily decipherable. No one wants to read a manual so as to be able to operate a remote.
Osaki 4000 massage chairs come with easy to use remote controls, however there are specific difference between the models Osaki-OS 4000 and 4000T and 4000CS and LS.
The 4000 and 4000T comes equipped with an LCD panel and a small remote, while the CS and LS features a completely wireless remote that you can easily use while reclining.
Of the two remotes, models CS and LS offers more ease of accessibility and comfort while in use.
Roller Intensity Adjustments
The roller intensity can be adjusted for the Osaki-OS models 4000,4000T and 4000CS. Roller intensity controls how hard the rollers can push against your body as it performs the massage.
The models have remote settings that enables you to set it from medium to high.
Osaki-OS 4000LS however offers no roller intensity adjustment. However, the detachable back pad can be used to control its intensity if you do not like the preset one.
When it comes to massage chairs, being comfortable is a key function, no one wants to sit in a massage in chair that feels uncomfortable. Durability and cleanability is also a consideration.
Osaki-OS 4000T offers an upgraded soft synthetic PU leather covering from the Osaki-OS 4000 model. The CS and LS do not offer the upgraded soft synthetic leather either.

The Osaki-OS 4000CS features a 2D roller type which moves along the track either up or down and left and right. With an extended length of 42″ the Osaki-OS 4000CS can provide a wider reach.
The rollers run along an L-track extensions that provides Glute massage beyond the spine. If you suffer from muscular pains that are below the spine, it’s likely that this is the model for you. When highly stressed, I feel pain in my lower left leg that extends up to my arms.

Want to know the best of the Osaki 4000 models that combines all the missing features in the previous models plus more? Welcome to Osaki-OS 4000LS model
Osaki-OS 4000LS Massage Chair Review
Osaki-OS 4000LS zero gravity massage chair is the best fit if you value a foot massage over adjustable roller intensity.
The 4000LS features all the functionalities of the 4000CS version except for the adjustment of the roller intensity which is not available on this version.
Another notable difference is that it offers a reflexology foot massage which the 4000CS version does not offer.
Osaki-OS 4000LS Pros & Cons
- It has all the Pros of the Osaki-OS 4000CS Model.
- Has removable back pad which can be used to tamper roller intensity when needed.
- Has rollers for feet massage.
- Solid 3 year warranty.
- Non-adjustable roller intensity.
We do not recommend getting the Osaki-OS 4000CS. It has virtually the same features as the Osaki-OS 4000LS at a very similar price, except it has no foot massagers.
Best On A Budget
The Osaki-OS 4000T is the best deal. While it is a little bit more expensive than the 4000 model, it comes with updated foot rollers, air compression, and soft synthetic leather. This chair will be much more durable than the 4000 and is worth the small increase in price. The downside to this chair is that it does not offer a glute massage and does not have the space saving option.
The Osaki-OS 4000LS is the only chair that offers foot massage, deep tissue massage, and glute massage. It’s a great option that also saves space in your home. It’s slightly more expensive than the 4000CS and doesn’t offer the difference in roller intensity, but in my opinion, it’s a much better value for your money.
