Osaki OP-Ai Xrest 4D+ (Free 2Yrs Ext. Warranty 🎁)

The Osaki OP-AI XRest 4D is a game changer! The 4D massage feels tailored and smooth, and it really helps ease tension after long work days. Comfortable and well built

For the price, it is a great chair. Other chairs for double the price feel the same to me. I have had it for 6 months now, without issues. Probably use it twice a week.

I purchased the Osaki OS-Pro 4D Encore about 6 months ago, and honestly, I’m still impressed every time I sit in it. I work long hours at a desk and often deal with upper back and neck stiffness—this chair has been a game changer.

What stood out most to me was the 4D massage mechanism. It doesn't just move up and down like most chairs—it actually adjusts the depth and pressure based on your body. The rollers get into the knots in my shoulders and lower back better than some professional massages I’ve had.

The foot rollers are another highlight—super firm (in a good way), and the compression airbags around the calves feel incredibly soothing after a long day. I also love the heating function in the lumbar area—it kicks in quickly and helps the muscles relax deeper.

The design is sleek, the touch panel is easy to use, and it even fits into a modern living room without looking bulky or mechanical. My husband and I both use it regularly and have different preferences, but the memory programs make it easy to switch back and forth.

It’s disappointing to hear this model is being discontinued—it truly deserves more attention. If you're considering a chair that offers real relief, thoughtful design, and quality craftsmanship, this one was it.

I love this chair! From day one it has delivered so much to my quality of life. I'm on my feet all day. I come home and get in. OMG! You can't go wrong.

I work long hours at a desk, and my back and shoulders are constantly tense. After a few weeks with the OP-AI Xrest 4D, I can say this chair actually makes a difference. The AI body scan adjusts the rollers to fit my back perfectly, and the deep 4D massage really gets into those tight muscles. It’s like having a personal massage therapist at home!
