L-Track Technology
The biggest upgrade is the roller technology. These new models feature L-Track roller technology. This technology allows the rollers to extend from the neck all the way into the seat to massage the glute muscles as well. This is a great features for anyone looking for a full body massage experience.

Some other upgrades include:

Deeper Massage Programs
The OS-4000LS & OS-4000CS have deeper massage programming. This is noticeably in the neck area where previous models have lacked. There is also additional padding in the back that can be removed if needed.

Adjustable Shoulder Airbags
These are a great addition. One of the biggest issues with the OS-4000 are that the shoulder airbags are too narrow for some users. Not on these models. The OS-4000LS/CS fixed this by adding adjustable shoulder airbags. The shoulder airbags can adjust up to 3 different widths to fit multiple body types.

Space Saving Technology
The OS-4000LS/CS have space saving technology and only need about 4” to go into a full recline; the Osaki OS-4000& OS-4000T needs 18”. This is a great feature to have if you are trying to fit the chair in a tight space.

  1. Trying to decide between the 4000CS and 4000LS. It looks like the CS allows roller intensity adjustment and the LS does not. Is that correct?

    Trying to decide on the differences between the two and which would be more important to me. I would choose intensity adjustment over foot rollers if the LS does not offer intensity adjustment
