ThunderX Core Loft

ThunderX Core Loft stol
Translate from : ThunderX3 Core Loft
If, like myself, you spend a lot of time in a chair, both in connection with work and as a gamer or hobby geek, then it is nice to have a proper chair to sit in. For a long time, there has been a very one-sided style of gaming chairs , but in today's test of the ThunderX Core Loft chair, we fortunately move away from that formula.

There are a few interesting things to look at here, which maybe on the list here don't exactly scream innovation, but which I will get into more in the test. This is, among other things, what ThunderX calls their CORE.RDY 360 TECH in the back support.

A tour around the ThunderX Core Loft

Seen on the surface, the Core Loft chair is just as good as many other gaming chairs on the market. However, the design is made in a way that leans more towards a "normal" office chair, and not quite so much the racing seat style, which has been the most used.


The chair comes separately and must be assembled before you can sit down in the seat. However, it is a fairly quick process that I managed in approx. 20 minutes. The Core Loft is, however, a heavy and impractical size, so it is a good idea to get help to haul the box in.

The materials on Core loft are a combination of steel and aluminum on the frame itself. It is rated for a maximum weight of 150 kg. The surface materials are fabric, which I personally think is nice to see, compared to the artificial leather that is often used on these kinds of chairs.

ThunderX Core Loft 4D Armrest

Core Loft comes with "4D" armrests, which can be adjusted in four directions such as height, width, forward/backward and angle.

ThunderX Core Loft backrest

One of the more special things is the backrest, which is made with what ThunderX calls CORE.RDY 360 TECH. Unlike normal back supports, which are stationary, the Core Loft is flexible and made to follow the user, even when moving around in the seat.

You also have the option of adjusting the seat cushion itself forwards and backwards. In addition to that, you can also adjust the angle of the seat cushion by 5 degrees. Finally, it is of course also possible to adjust the height of the chair with a gas cartridge.

The backrest can also be tilted back if you want a more reclined sitting position while playing games or watching YouTube. It is made with what ThunderX calls Synchronous Tilt, which means that the seat and backrest are not locked at a fixed angle, but tilt independently for a more comfortable result.

It is possible to set how light or heavy the rocking effect should be, or you can choose to lock the backrest completely.

ThunderX Core Loft wheels

The wheels on the Core Loft are made of PU plastic and provide a really nice glide over an ordinary floor, without skating around too much. I don't have any carpets in the house, so I haven't been able to test that part.

The Core Loft also comes with a neck pillow that can be fastened to the chair. It is supplemented by another pillow, which can either be used as a footrest, extra support for the back or to wear the arms on, for example when playing with a controller.

On the back of the back, ThunderX has made a small pocket if you need a place to store small things.


I've had the ThunderX Core Loft visiting for a few weeks now. I've used it as my primary chair during that time at my desk for work and gaming along with time at the hobby table.

I have, after a long time previously in chairs made of leather or synthetic leather, become very tired of the materials in office/gaming chairs. I definitely prefer mesh and fabric, as materials in a chair in that regard, the Core Loft fits really well.

The disadvantage of fabric, and especially lighter fabric, such as the gray we have for testing, is that they can be more difficult to keep clean over time. The cover on the Core Loft is not designed to be removed and washed. I have already discovered a small stain on one armrest. It's 100% my own fault, as it stems from some stray paint from the hobby table.

If I had to choose, I would choose the dark version of the chair for the same reason, as it will probably look nicer for longer. However, it will probably vary quite a bit depending on how unlucky you are with your coffee cup, for example.

Core RDY 360 TECH

Another part of the chair that sets it apart from all other chairs I've tried is the dynamic CORE.RDY 360 TECH back support. In short, it is made so that the back support is not fixed, but instead is mounted on a flexible mount that feels a bit like a spring. This means that it follows you and adapts to your sitting position in the chair. I was a bit wary to start with as the mounting felt a bit loose.

After a bit of getting used to, it was a super good experience. I often change position in the chair during the day, or a longer gaming session, and it is super nice that the back support comes with it. Despite the fact that it followed my movements and shifts in the chair, it still feels firm enough to provide good support.

If you combine that with the many options for other customization, such as the one seen with the backrest and seat cushion, the sitting experience with the ThunderX Core Loft has been a super good one.

I never really found a good position with the neck pillow. I simply felt my head was pushed a little too far forward. Fortunately, it is ready to take off.

Footrest Core Loft

However, I have used the other pillow quite a bit as a footrest. It has been a nice addition to the more laid back gaming sessions.

It is one of the best chairs of its type I have tested. Build quality, seating comfort and the possibility of lots of customization mean that I am super happy with my time with the Core Loft.


The only thing I think stands out a little in relation to the build quality is the armrests. They are a little too similar to all the other armrests that we see on virtually all gaming chairs. They rattle quite a lot and don't quite match the good build quality of the rest of the chair.

However, the cushions on the armrests and the fabric surface are super comfortable.


The new functions and the high build quality mean that the Core Loft chair is not exactly cheap. I can currently find it with an online price of just over 500$. It is on the upper end, but certainly not the most expensive gaming chairs on the market.


My experience with the ThunderX Core Loft has been super good. Although I try to supplement my working day with standing work, during the course of a week I end up sitting a lot in connection with work and hobby geekery.

This means that a good chair means a lot to me and it is also a product that I would recommend to others who sit a lot and take it seriously in relation to general well-being.

As I touched on earlier, the ThunderX Core Loft is one of the best office/gaming chairs I have tried outside of the very expensive Herman Miller type chairs.

Controller cushion Core Loft

The Core Loft doesn't scream gaming chair, and I'm personally really happy with the subdued design. The build quality is super good all around, perhaps with the exception of the armrest, which is a little too reminiscent of someone taken from any other standard gaming chair.

The price is on the high end, but compared to what you get in terms of quality and innovation, I don't think it's unreasonable.

We land with a final score of 9 and a Great Product Award for a high quality chair that stands out from the crowd and tries new things.


  • Good build quality
  • Good materials
  • Lots of customization
  • Flexible back support is good


  • The armrests are a little disappointing
