Osaki OS-4000 Review
- Zero-gravity recliner and auto massage modes for maximum massage experience
- Comprehensive human-like massage that simulates hand massage to a large extent
- Takes a lot of space especially when the zero gravity recliner is used in massage
- The massage pressure in the calf region is at times intense for some users
Osaki OS-4000 – Functionality : 4.5/5
The specialty of OSAKI OS4000 is its zero gravity massage. When I heard of this model, I was quite apprehensive about the feature. But the science behind the technique and the relief from the massage impressed me. The inclined position removes stress from the back and makes back massage more effective.
I had to clear out a lot of space to use the recliner. And when my feet went up, I was not comfortable for the first time. Eventually, I understood that the ZG position is perfect for spinal alignment and provides greater relief.
Also, high pillow design that comes with this chair helped me stay comfortably at ZG position throughout the massage
Osaki OS-4000T – Style: 4.5/5
The exterior option of this chair is best suited to most decors. Charcoal, burgundy and black, cream and beige & black and beige are the four different color variations available.
The exterior is made with resin leather, meant to give the soft and comforting experience of sinking into the chair and inner body is built with steel, and so far I have cleaned the chair with damp sponges only. I chose the cream and beige as it went well with my flooring. So I have to clean it often.
No complaints though. Cleaning and maintenance of the chair are quite easy. It’s clearly stated in the manual that water or any cleaning agents shouldn’t be used on the massage chair. But using a dampened sponge or cloth would cause no harm.
The LCD and the wireless remote lives up to the executive look it promises. Display glows in the dark as well and is meant for user-friendly operations. The microprocessor is intelligent and delivers the performance that matches the look. I would be happy to give 4.5/5 for the style quotient of this chair.
Osaki OS-4000CS – Durability: 4/5
With the inner body built with heavy duty steel, this chair is highly durable and with my usage frequency (Almost thrice a day as I have a big family of 8), I can vouch for this!
The best part about this chair is that every part of the body is taken care of. Shoulders, neck, upper back, hips are all given air massage using the air bags positioned in the chair.
Arms can get both vibrations as well as air massage. Vibrational massage for the buttocks and airbag massage for the calf rest are unique features of the OSAKI chairs.
I needed a white glove service for the chair. It was delivered in a dismantled position and given the sophistication in assembling this chair; I decided that I might need expert hands and OSAKI team were ready to do it, and I was happy that they did it without any extra installation cost.
Any returns can be done within 30 days. But before returning, it’s necessary to get the Return Merchandise Authorisation from the company. This requires a registration stating the invoice number. For further details, you can check their website. I haven’t had any issues with the chair so far. So I have not gone through the process.
Also, OSAKI chairs have a three-year warranty and guarantee for all parts, labor, and framework of the chair. This guarantee is for any faulty parts, poor artistry or any possible defects in the structure of the chair.
Our Overall Rating: 4.5/5
On the whole, am happy with OSAKI OS 4000 and the massaging experience is hugely comforting. I would give a 4.5/5 for my massage chair.
