Zero Gravity

Auto Body Scan

True Ergonomic S-Track

Full Body Air Massages

Zero Gravity

Inspired by NASA technology, the Zero gravity position is the perfect position to enjoy a massage, aligning your back relative to your thigh at an optimal level of comfort. When reclined into the zero gravity position, the complete weight of your back is virtually supported by the backrest which maximizes the intensity of the massage. This also reduces the vertical stress on the spine. There are 2 stages of zero gravity, the 2nd being more reclined. Study show that when the legs are at or above heart level, it promotes better circulation.

Auto Body Scan

Equipped with the latest technology, It allows for the rollers to map the back curvature with even more accuracy, which translates into a more precise massage hitting all the key areas.

True Ergonomic S-Track

The OS-4000 Zero Gravity massage chair is ergonomically designed to contour a variety of spine shapes. The Spine curvature is unique from one individual to the next. The S-track system allows the roller heads to massage along the back from the neck down to the lower spine with a consistent pressure in the massage, along with a comfortable support. The typical massage tracks, being linear, create an inconsistency in pressure applying weak massages in the neck and lower back.

Full Body Air Massages

Through innovative engineering, we have reduced the total number of air bags but have increased the volume and surface area of massage. By doing so the total number of working valves has drastically reduced from prior model. Which ultimately puts less stress on the chair, making it one of the most mechanically sound massage chairs in the market.

Placed in the lower back region of the chair are 2 heating pads that enhance the massage experience.

Wireless Controller

Located on the top right of the main remote you will find a compact wireless remote allowing you to control the main features of the chair without having to struggle to reach the main remote in the reclined position.

Extendable Footrest

At the start of the massage, the chair will fully extend out and then retract.

Once the foot massager has reached the desired length, firmly press your totes down to indicate the chair to stop.

Excellent massage chair at a great price

Excellent massage chair at a great price
Finding the right chair was a difficult process, but after reading many reviews and looking at different product videos we selected the Osaki 4000. Right from the moment we ordered we got good tracking from the link provided and the chair arrived on the scheduled date. Getting the base of the chair in the house was a bit of a challenge, but it has wheels which made it easy to get to the room where we wanted it. Assembly was easy except for getting the arm panels installed. The holes don’t line up evenly, so the trick to assemble without cross-threading the bolt is to push the bolt all the way through the support bracket and then locate the threaded hole on the panel. This is challenging as you can’t see the hole, but will allow you the right angle to align properly. Once the panels were on then all that was left was the control module. You will need to remove the mounting bolt and after fitting the module on the support post reverse the bolt to come in the other way. This will allow you to tighten it, otherwise it won’t tighten. At this point it was ready for the first massage. It honestly surpassed my expectations and I was very pleasantly surprised. There are so many options with the available programs and then the manual selection of features. It would be nice if all the controls were back lit as it is difficult to read the features in low lighting. We have had it now for 5 days and we have done about 20 massages in my family. It is relatively quiet and very comfortable as you can adjust the settings. The airbags apply a lot of pressure but you can adjust them to a lower setting. Personally I look a firm had massage and need to max the strength of the rollers where my daughter prefers it at a low setting. I’m 6’ tall and probably at the upper height limit for the chair. The leg massagers automatically adjust to the length of your legs which is excellent. The only disappointing thing is the arm panel air bags. The shoulder supports prevent you from getting your forearm completely in the space for the arm massage airbags. Perhaps if you are shorter this might work better. Also, the operators manual needs to be rewritten as the English isn’t the best. I would recommend the company do this as it would be much better for the consumer. I have to say I may be in the honeymoon phase right now, but I really like the chair and hope it keeps working as well as it is now.
