DXRacer King Series (OH/KX28/NB) PC Gaming Chair Review

Thoughts about the DXR

With my seating and use of the chair, I immediately noticed a difference with the DXRacer and the Aeron. The high density foam used in the seat bucket caused discomfort in my legs. Due to the length of my legs and the position that I kept them during my sitting, the KX naturally let my thighs “splay” outward a few degrees. Due to this, the foam used in the seat bucket was leaving indentations in the bottom middle/side of my thigh… and pushing into nerve bundles, which led to my discomfort. Looking at the design of the seat bucket, I see now why this issue happened.

Legs in full splay:

Legs forward:

My legs naturally landed between these two positions, so the foam corner and the edge of the raised seat foam both combined to make for a perfectly placed “wad” of foam that my legs would mold around. This is what led to my discomfort. I had to “retrain” my legs. What would have likely been better, in my case, was if this foam was lower and the side bolsters of the seat bucket were able to keep my legs properly aimed forward.

As a comparison among DXRacer models, here are two units that make it easy to see the seat buckets with the design difference. First is the King Size. See how the height of the seat cushion fills the seat bucket (foam is flush with the tops of the side bolsters), and make it so that the legs cam move over the side bolsters?

Now, this is one of their “Formula” chair models. See how much lower the seat foam is in the bucket? and how the side bolsters are exposed, adding a funnel effect to your legs to keep them from splaying outward?

This is what I am used to on the Aeron chair. It has a natural “side bolstering” affect that orients my legs forward. Now, this is not to say it is a design flaw. It is to say, that if you have longer legs and are taller than 6ft 5in, there is a chance that this seating design may also affect you. For you bigger people with thinner thighs, this may also affect you. If you are used to your legs funneled forward, and not splayed outward, this design may cause you issue. Since the whole reason to spend premium money on a premium seating solution is to have long term comfort, I would feel disingenuous by not bring this up. My body type is on the top end of a body size matrix. And due to past injuries and my need for comfortable seating, I’ve done a bit more research than most. So I am sensitive to less than optimal seating.

When I initially started using this chair, the position of my legs, combined with the foam pushing into the backs of my thighs, made for a less than ideal sitting arrangement. Long term comfort was not in the cards. Doing a bit more research, I noticed many others complaining about comfort. Which is what made me want test this chair longer. What I have done now is to train my legs to be more forward oriented. What I *think* would make this seat cushion ideal is if there were 2 weights/types of cushion foam on the seat, and make the majority of the seat base the current foam while making the leading edge and top corners a memory foam with more give. So that you don’t end up with those dense foam edges potentially pushing into the backs of peoples legs. Also, this may not be the proper term, but it will get the point across… you also need a little time to “break in” the chair. The more you use the chair, the more you get used to the chair. And the more the chair gets used to you! As of now, at this time of writing in mid/late April, I find the chair much more comfortable than my initial impressions when I first swapped in the October/November time frame. This, I think is very important. In this “microwave” age of instant gratification, people *expect* this chair to be comfortable, right out of the box. This is not the case, but it is attainable. I remember having to adjust my Aeron for many days before I had the lumbar support just right, the seat orientation just right…. the arm height, etc…. you get my drift, right? This chair is no different. It had one main problem that I had to overcome, and after that, it has been very comfortable. The seat still feels a bit on the “too firm” side, but it is supportive and comfortable. I have to think that the foam selection was potentially due to persons that were on the heavier side of body weight than I, and the need to find a cushion that could take that. Just a theory on my side.
