The dual backrests on the Alpha cradle your entire back – giving you full lower-to-upper back support. The two individual backrests wrap around your spinal muscles to work with your back, not against it – keeping your back straight and supported. Unlike single-backrest chairs, dual backrests are proven to alleviate back pain and provide more comfort.

- 【Breathable Mesh】: Highly breathable mesh seatpan supports the user’s weight with enhanced air circulation and flexibility.
- 【Customizeable to your needs】: You can personalize the Duorest Alpha model to fit your body shape and size. It's designed and built for your individual comfort and support. And covers more area of your back than most office chairs on the market. Plus, you can lean back up to 135 degrees, adjust tilt tension, and lock the chair at your desired recline angle.
- 【Max comfort, in the office or at home】: It’s time you experienced a chair that relieves back pain and offers all-day comfort. The Duorest system reduces spinal pressure by more than 44 lbs compared to single-backrest office chairs and supports the natural curve of your spine to keep your posture straight. You can finally stop fidgeting in your seat to find the right spot or getting up every hour to take a break from sitting uncomfortably.

Its comfortable when it stays in place. No matter how many times I adjust or tighten the back it ends up falling and not being in an ideal spot. I spent a ton of money on this chair just to have it constantly need to be lifted and adjusted throughout the day. Pretty frustrated.

Edit: Duorest reached out to me to cover the issues I've been having, and offered me a free replacement. They said it seems like the chair I got was damaged/defective, so I took the offer and gave them the benefit of the doubt. This time around, the seat pan locks firmly in place, it no longer slides back when I adjust myself in the seat. The back adjustment also locks firmly in place, and I've had no slipping. The original chair didn't seem to have any grooves in the back to help lock in the height. This time around, when adjusting the height, it feels like there's some grooves or something at each level to help the chair lock into position. So it seems that it was in fact just a chair that was damaged in transit, or otherwise had a bad QC. But I'm very impressed with Duorest for reaching out to me about the issues from my review, having actually read my review to address my specific problems, and having such a quick and easy solution. Now that the chair functions correctly, I would highly recommend this chair and brand.Original Review: I've been using the Duorest Alpha (all black) for several months now. I got it to replace another ergo chair who's back adjustment broke, based off of the stellar reviews and unique design. I can say, the back rest is amazing. It cradles well, and while it can be a bit warm since it's not mesh, it's one of the few chairs that hasn't left my back hurting after a long session at my desk. But beyond this, the chair has been pretty disappointing.The main issues are the headrest, the seatpan adjustment, and the back adjustment. I'm not really a fan of the loosen to adjust, then tighten the wheel to lock it in place style of back adjustment on chairs, but if it's good quality, I don't really mind. I don't adjust my back height unless it slips out of place. Well, pretty much since I got this, it hasn't done great at holding it's place, but it's gotten significantly worse over time. No matter how tight I turn the knob, it still slips pretty much any time I leave the seat, all the way to it's original position. I'm a rather tall person, so this doesn't work for me, as I find myself hunching over to meet the back, which doesn't help me at all. Incredibly disappointing for the price, and the reviews.Other than this, the seatpan, while it adjust forwards to where I need/like it, it doesn't lock in place. So any time I readjust myself and slide back in the chair, the seatpan slides with it. And it can often be a pain to get it to extend all the way forward again. Upon inspection, the mechanism for it just doesn't have any lock points other than for it being all the way back. And the head rest is kind of flimsy, which I expected, but the real issue with it is the bar it's on extends between the shoulders of the backrest. This means that reclining in this chair is incredibly uncomfortable, as, at least for me, the bar ends up between my should blades.While I love the design, for the original price of $600, let alone the now $650 price, this chair isn't worth it. It's displayed as a more premium version of the chair (as well as the only one you can get a mesh seatpan with, which is a must for me), but it is far from anything premium. I haven't tried their other, cheaper chairs, but I'd recommend looking at those if you're sold on the backrest design, as maybe you'll have better luck, or at least be out less money if you experience similar issues.
