ThatSit Balans Adjustable Ergonomic Kneeling Chair with Backrest, 10-Year Limited Warranty, Designed by Peter Opsvik, Natur/Black

This should’ve been easy to build, but it was extremely difficult. Pieces didn’t fit quite right. It was a real struggle. For this price point, it should go together much easier.

I have been using this chair for three weeks. I bought it because of back pain I was experiencing in my typical desk chair. (I have no back medical issues). I assembled the chair by myself although a second person would be very helpful. Construction diagrams are horrible, but using common sense you can put it together. When adjusting this chair for you, be sure to study videos of people sitting in this chair online to observe the proper body alignment you are striving for. I have to admit I’m hefty lady so I chose this chair for it’s sturdy construction and numerous adjustments. It was an extravagant purchase for me but worth it! Immediate relief of back pain for me. I use it eight hours a day at my desk. It sounds funny, but this morning I put a piece of nonslip rug padding on the seat so I couldn’t slip forward when both shins were on the shin rests. I know I will like this addition :-). Very happy with seller communication.

Hard to put together. Broke after 4 months. Difficult/impossible to repair.This is one of the better-looking kneeling chairs options out there but it is fragile and overpriced.Do not buy this chair – choose a cheaper alternative!!I regret not following other reviews that warned of the same issues.

Edit: The below review is still accurate, however after using the chair more extensively I must say the design is fantastic. There are a few other chairs on the market - more expensive - with longer delivery wait times that are more adjustable/flexible - but that being said this chair allows for a much wider range of natural movement. It’s easy to shift positions and the chair itself is also light and quite easy to maneuver. Still very expensive and many will not take the risk - but if you are suffering - give it a try. I’ll add that weighing 190lbs at the time of writing - I feel as though I’m almost at the limit of what the chair will handle - doesn’t feel as though it’s about to collapse or anything - but it also doesn’t feel incredibly sturdy either. It’s not a chair you can lounge or relax in - IMO - don’t fall asleep in it LOL. The fabric covering on pads/seat also seems quite sturdy - but not exactly soft - so if you have delicate skin - you might need to wear long pants or cover with something softer etc.While there's no question this chair is far superior to the many $150-250 competing products on the market, it's absolutely NOT worth $800+ in my opinion. The instructions were a joke, screws and other parts were rolling around the box - torn bags gave me the impression this item was purchased/returned... Everything except one of the wooden dowels was there. Ultimately, the chair is functional and works as advertised. I will say, however, it's not quite as adjustable as I had hoped. By this I mean the ways in which the chair is adjustable do not actually provide the level of movement, or movement in the right direction to facilitate a more custom fit. As a reference I'm around 5'9" and swing between 185-195lbs. The seat padding is NOT sufficient in my opinion and here's one area where some of the lesser priced chairs, of which I have purchased several, actually win out. At the end of the day, I think this company, and so many others are to a degree exploiting our pain/desperation. I'm just not sure how this price tag is justified.

Boy, I'm pretty handy with a wrench and stuff, but this was by far the worst assembly I've ever been thru! Every step was a MF, there's 100 little things they could do to make the consumer experience much much better. Cool chair and all, but honestly if you don't want to wrestle the chair for 2 hours then just pick something else.

This chair is rather incredible. Pricey indeed for those that are not aware of the endless benefits to sitting in the correct posture, however priceless for those who do understand. This chair appears to be designed to support the perfect posture both in and active and inactive position. I use the chair daily for about 9-10 hours and and I am able to sit comfortably in the perfect posture the entire time. The adjustability of the knee rest really change the game comparatively speaking to the variable balans which I also owned before this purchase. I find my self utilizing the various positions available in this chair without even thinking about it. At the end of the day I realize I feel great. I have no aches and pains and feel much more alert. The body is designed to allow the energy to flow without resistance and many of the ailments and illnesses that people have are deeply rooted in simply sitting in the incorrect posture. This puts pressure on nerves which cause pain. Pain causes stress which increases the cortisol levels in the body. When one gets in the habit of sitting in the wrong position they are also teaching the body the habit of producing the stress hormone. When this hormone is released it puts the body and mind in flight or fight which takes the energy away from the body and mind that it needs to not only focus and think clearly, but it also takes the energy that is required to generate more t-cells and embryonic cells. This means the body learns to redirect the energy it needs to develop, grow, and prosper to simply surviving. This like buying a care and never keeping up on the maintenance and eventually has quite a noticeable affect on the body. What affects the body also affects the mind and emotions. If the body is being affective negatively then so is the mental and emotional reality of the individual. Simply sitting in the correct posture there for can have profound benefits on the wellbeing of individuals, especially those of us who have developed that habit of sitting in the incorrect posture. I would not recommend worrying too much about the color and material that this chair is made from. I chose this color because it was half the price and many of the other options with different fabric. Although expensive than most, this chair is well worth the purchase and should be the standard that every furniture company works towards and upholds. This chair is well made, comfortable and stylish. I would recommend this chair over getting treatments for your back that are not fixing the problem at its source. This chair gets a 10 stars out of five for me and my friends would tell you I'm the most particular individual they know. I am not easily awe'd.
