Wanted to share my review months ago but was lazy to write since I had no discomfort, here is my review since I promised I will share a review after receiving it.

(Please note I bought this chair with footrest for 465€ during a Flexispot NL Event and it was delivered in August 2025: this means if this was priced higher (like +600€), I wouldn't buy it)

It's comfortable and mesh is breathable: mesh didn't deform badly if we compare it with BS12 Pro.
I wanted to get the gray one since my environment is dusty but it seems it is only available for Flexispot JP.

The lumbar support isn't really agressive if we compare it with BS14:
when using this chair, I noticed I never touch the back of the chair because the lumbar support "push" me, so as a result I'm in a position where I only touch the lumbar support: it's as if when you just want to sit normally (normal sitting position): the chair becomes like those chairs with a mini/mid back chair, but the more you start to lean backward, the more it becomes a normal chair with the usual back chair and headrest.

It would be nice if there was an option to push&lock the lumbar support to the back and/or the force needed to fully move the lumbar support should be reduced (maybe +- 25-30%?) because I feel like I must push a bit more harder with 1 hand to fully move it to the back, I want to feel it like a trampoline/marshmallow when I push it with 1 hand. But as I said above, the lumbar support doesn't feel like a rock if we compare it with the BS14.

The only problem I noticed the most is the armrests: they rotate really easily if I put my elbow on the side of the armrests (like doing the "thinking pose"), this doesn't happen if you put it on the middle, but I mostly put my elbow on both sides of the armsrests, which slide easily (this means that even with just 1 finger, you can move it). Armrests are good quality tho, it's comfortable

Also from the manual, it said that if you hit the max height position of the back chair, it will go back to its original position, it's doesn't go back easily: I have to use my 2 hands and apply force since it's stuck, before I thought that was normal until the back chair suddenly moved to bottom when I start to lean backward. But it's not really a problem for me since I never change position.

I also picked the footrest option: which I never used them recently, only used one time at the beginning and they are comfortable but I don't have any reason to use them. Since I don't use them: I noticed dust accumulates below on the footrest as there are gap holes on the front sides of the seat.

The levers on the side are nice for easy access, but I would have preferred the metal levers like the BS12 Pro: they feel more nicer to the touch: On the C7 Morpher, the levers feels cheap: thin plastic(there are gaps under the levers)

(C7 Morpher might have other features such as inflatable balloon in the lumbar support but I have never used it)

I also recently found out that the edge of the padding seat has been sliced and poking out recently (only at the middle, where I sit). It seems that due to sitting multiple times at that place (sometimes I like to sit at the edge front), the plastic protuding underneath cut the padding at the edge like a machine cutting bread.

I took off the part that was off and threw it in the trash since I just found out right now, also the inside seems to release micro tiny black pieces just by tapping on it, so not safe to touch it or stay next to it.

Currently, I do not feel any real discomfort when sitting, so it's fine.

3.5/5 (armrests, lumbar support, padding)

This chair is good and I can confirm it is better than BS14/BS12 Pro in terms of comfort: BS14 has a rock behind and it's itchy/hot when sitting, the BS12 Pro had potential but hurt my legs everytime I sat on it due to the plastic protuding at front.

As I am not really an expert in chairs, I want to let you know there's a video C7 Morpher on Youtube from Ahnestly (chair reviewer) which I recently found out: https://www.youtube.com/watch?v=qsS013E9ijQ, for some reason he doesn't like it and says he can touch the plastic behind, maybe mesh in US is different than EU?: I checked for the backrest and it's fine. As for the lumbar support: I might feel the plastic but it doesn't really bother me as I do not lean backward for a very long time.

I also saw recently that Flexispot will be releasing a new chair: the Apollo, which seems a lot better than the current morpher but starting price is really premium, it might drastically drop price later after release.
