The primary differences between the Osaki 70000 Massage Chair and the Osaki 4000 Massage Chair are as follows:
1. # of Airbags
The Osaki 7000 massage chair has 46, whereas the Osaki 4000 massage chair has only 32 airbags. The extra airbags in the Osaki 7000 are found in the head, hips and thighs, waist area, and seat. These extra airbags contribute to what Osaki calls the “swaying massage” in the 7000. The airbags move the pelvis, seat, and low back in such a way that the low back feels to be gently stretched in a rotation motion. Very soothing feature of the Osaki 7000.
2. Length of Vertical Roller Track
The length of the roller track on the Osaki 4000 is 30″, which is already a good length. The Osaki 7000 goes a bit further down the low back into the buttocks with a 31″ roller track. I believe this is the longest vertical track of any massage chair with which we are familiar.
3. # of Motors
The Osaki 4000 massage chair has 7 motors and the Osaki 7000 has 13 motors. More motors mean less wear and tear on one particular motor. The workload of the chair is distributed throughout more motors for less breakdowns.
The Osaki 4000 has low back heat, but the Osaki 7000 has a more full body heat, including heat in the head, neck, shoulders, back, arms, hips, calves, and feet. More comprehensive heat than in any other chair model that we carry.
5. Stretch Program
Osaki introduces a new Thai style stretching program with the Osaki 7000 massage chair. Stretching on a massage chair is more like a milking motion of the soft tissue. The chair back and ottoman raise up and down to induce a passive motion to the joints and soft tissues of the spine. The Osaki 4000 does not have this stretch function. The stretch function on most massage chairs is almost always a favorite for the user. You will enjoy the stretch function.
6. Zero Gravity
Both chairs boast a zero gravity feature, which is a great feature for low back pain sufferers. It allows for the weight of the body to be more evenly distributed in the reclined position so that less stress is placed on the low back.
The price of the Osaki 4000 is $2895. The price of the Osaki 7000 is $3790. We always have a low price match on any of the models we carry. You just need to decide if the differences in the features is worth the difference in price.
Well, that should just about do it for a comparison between the Osaki 7000 and the Osaki 4000 massage chairs. I hope this helps you make your decision. Remember that the warranty on all Osaki massage chairs is 1 year comprehensive in-home. We offer a 90-day money back guarantee and our best price promise.
