Osaki 4000 Massage Chair vs. Inada Sogno Dreamwave (Part 2)

Comparing the Osaki OS-4000 to the Inada Sogno (Part 2)

This is Part 2 of a 2 part comparative review of the Osaki OS-4000 and the Inada Sogno Dreamwave. In Part 1, I discussed 5 general differences between these two very popular massage chairs, but today I will go into specific chair features and functions to help you in your due diligence.

Osaki 4000 Massage Chair

6. Zero-Gravity – The Osaki 4000 has a zero gravity feature which, by definition, is a 30 degree tilt of the seat in the zero gravity position. The Inada Sogno’s seat stays horizontal during all programs. Zero gravity is a great feature for decompressing the low back.

7. Airbags – The Inada Sogno Dreamwave massage chair is an airbag monster…over 100 airbags. The Osaki 4000 is a little more typical of most massage chairs with 32 airbags. Rollers are typically used for the spine, whereas airbags are used for every other part of the body, i.e. legs, feet, thighs, arms, shoulders, waist, etc.

8. Dreamwave Technology – One of the unique therapeutic features of the Inada Sogno is the use of airbags to move the seat from side to side and up and down in a figure 8 motion. It introduces passive motion to the pelvis and low back in a very gentle swaying motion that is very soothing to the user. The Sogno is the only massage chair that has this feature, as far as I know. The Osaki has airbags in the seat but not at all like the Dreamwave technology of Inada.

9. Thigh Massage– a lot of the newer chairs have airbags that compress the outer aspect of the thighs, where the IlioTibial Bands (ITB) are located. The Osaki 4000 and the Inada Sogno have these airbags, however the airbags on the Sogno actually massage the ITB in a wavelike motion and it feels like a true massage. The Osaki 4000 simply compresses against the thighs without the feeling that much is being done therapeutically. If you’ve ever had low back, knee, or hip problems, the ITBs are probably pretty tight on you and the Inada Sogno will make you realize how sore they truly are!

10. Heat – Both chairs have heat, but the heat of the Osaki 4000 is definitely more noticeable than the subtle sacral heat of the Sogno. If you like feeling the warmth, the Osaki wins that hands-down.

11. Cervical Traction Device – Inada innovated this feature. It is a headpiece that has airbags to massage the neck and the trapezia muscles (you know…the muscles at the top of your shoulders that get tight when you sit at a computer all day). It is a phenomenal feature in the Sogno. The Osaki 4000 has a headpiece that mimics Inada’s Cervical Traction Device, but doesn’t have the airbag massage that the Sogno does.

12. Arm Airbags – Both chairs have arm airbags, but the Osaki 4000 airbags basically just cover the forearm and wrists, whereas the Inada Sogno has extensive airbags that compress the fingers, wrist, forearm, and upper arm.

13. Roller Track Length – The vertical roller track length of the Inada Sogno is 28.5″; the roller track length of the Osaki 4000 is 30″. It feels like the Inada massages lower down into the buttocks, so I would say that the Osaki goes higher up the neck with the extra 1.5″.

14. Height and Weight Recommendations – Inada has always had the motto “If you can fit, you can sit.” So, regardless of your weight, if you can fit in the chair, it will function just fine. Osaki, on the other hand and like most massage chairs, express a weight limit for the chair’s optimum function, and that is 265 lbs. As for height, the Inada can cater anyone comfortably from 4’11” to 6’4″; Osaki best fits someone from 5’4″ to 6’4″.

15. # of Motors – Inada has 13, Osaki has 7.

16.  Remote Control – The Osaki 4000 has a pedestal remote, the Inada has a free remote that tucks into a small side pocket.

Those are the major differences between the chairs. Some features that they both have include body scan technology, ottoman length adjustment, calf and foot massager, quad-style rollers that knead, tap, and compress, vibration, auto and manual settings, and a stretch program.

I hope this assists you in your massage chair buying research. After reading through the comparisons, you will have to decide if the price of both chairs is justified.
