For it's compact size and height it is quite stable and durable (fine for those weighting 110+ kg).

Chair arrived today --- a long wait but worth it -- the chair is wonderfully made and looks great (get the blue one).
Just a comment from a NOOB -- follow the instructions when you first open it -- the YouTube video is easier than the printed instructions. It is a little fussy at first, but once you have open and closed it a couple of times, it really works well. Don't forget, start by hanging it up from the carabiner...

It was a long two years ago that I saw an intriguing camp chair idea and decided to back it. Then: Covid, supply-chain issues, etc. Finally, the chairs (one for me, one for my wife) arrived today. I think they'll be great for their intended purpose.
We had returned from a missions trip to a country where people often sit customarily on the floor -- but back troubles made it very difficult for me to sit that way. So the appeal of a light-weight, compact, yet sturdy and comfortable chair that I could carry in a day-pack was irresistable. I look forward to using it for its intended purpose, when these covid travel restrictions finally lift!

Just got my backer reward today. First of all, looks beautiful. The blue finish looks great. I carefully unpacked and set up my chair for the first time as the directions indicate, and although one lock setting was a little tight and took some convincing for the first time, it worked as advertised! I’m also 6’1” and 315 lbs so the sturdiness and size was put to the test and turned out really pretty comfortable and stable! It’s not gonna replace one of the big 4-legged camp chairs that weighs 20 pounds as a regular daily campground chair, but it will absolutely live in my vehicle and go with me everywhere because of how light and portable it is. Overall I’m very happy and look forward to putting this to field use.

So pleased with these chairs. Very light weight but surprisingly sturdy.

Unlike many people who only wanted it for one of those summer camping trips. I wanted it as an EDC (everyday carry) for work! I drive a subway for a living and there are some downtime when the line is a little messed up or with closures. There isn't a lot of places to sit in a station platform, and with covid it's not very possible to social distance at one bench.

I'm very happy I got this amazing feat of engineering in my hands now and I'm buying a Molly attachment for a large water bottle to place it on my bag.

One thing I do recommend is to deploy and retract it multiple times to soften it up and also pull as hard as you can before twisting

Thank you guys I can't wait for the next iteration keep doing amazing work!

I also wanted to use it while training other operators however a little bit of movement and there is some instability and you have to use your own body to compensate however like many others have said this is not a lounge chair this is a portable beast and should be not compared any other way

Super lightweight, really comfy. No better chair that is this small, light, and comfortable exists. Awesome product.

Recently, I spent over (2.5) hours at the World of Wine’s immersive ‘History of Wine Museum’ in Porto (Great Museum, BTW!). There is no way I could have taken that much time to thoroughly absorb its rich offerings, if I had to stand the entire time. Thankfully I had the Zen X-II. It will always be an essential part of my travel kit. A true game changer in this world of endless lines. I purchased the original siTpack and was impressed enough by it to then support the development of the Zen X-II through Kickstarter. The original version worked great, but the Zen X-II improved on it by being more comfortable, more compact, and lighter. Besides obviously having a great design team, they have a great customer support team as well.

Kickstarter backer here. I have used it a handful of times and I love it so far. Pretty quick to deploy (and pack) and comfortable when you're sitting on it. There are a couple of things I've noticed, though. When it's cold, getting a grip on the metal legs to set up the chair can be tough. I'd love it to be a bit more grippy, but then how would it slide back in smoothly and also maintain it's strength? The base is pretty reasonably spread out, but if you're on pretty uneven ground, you may have to take some time to find the best footing for it, so you don't tip over when you sit in it (it's just physics!)

Also, you'll definitely want to lean back into it, that's what it's designed for and how it works best. leaning forward and rest on your knees is fine but doesn't work quite as well. Leaning back creates the correct tension on the seat for more stability.

Overall it's great so far, good quality and super light! I'm glad I have one!

The Sitpack Zen is light and doesn't take up much space in a pack. It's also quick to set up. I hike and hunt for long distances through the mountains. I like to use it to give my legs a break when I find a spot I wish to spend some time. It's not as comfortable as a chair but way lighter and more convenient to carry.

First things first, this is not an arm chair. Instead it is a serious piece of technical outdoor gear. Now, if you are strong enough, and crazy enough, by all means carry an arm chair with you on a hike, but unless you are willing to do that, then it is only rational to expect, and accept, the design compromises made which keep the chair as light as a litre of water, and tall enough to sit on, and get up from, as easily as most dining chairs while almost certainly still being the most comfortable seat you will find in the wilds..

The main compromise is on stability. In order to achieve the height, while minimising weight, when extended, the feet are relatively close together. Because of this it is necessary to sit 'neatly' in the chair, and not slouch or lean. However, this is not hard to achieve and still better than most stools, thanks to the back. Despite the apparent inconvenience, it still gives greater comfort and ability to rest and recover than anything else I have found 'in the field'. Like all hammock style chairs, it can be a little uncomfortable to initially get used to if sitting for longer periods but it is easy to pad with some clothing or a sit mat. Plus, remember, it is not an armchair.

One advantage to the narrow design, however, is that I can sit in it with my cape style poncho covering myself and the chair with my rucksack between my knees. This does a very good job of creating a rapid, yet effective and comfortable shelter, against rain and wind and I look forward to trying that out in the deeper Winter weather. I have already managed to sleep in the chair, under the poncho, and didn't find the experience any worse (but sadly no better :) ) than trying to sleep in a coach or aircraft seat. While not something I'd like to do often, this does make the seat and poncho combination a potentially valuable part of my survival/emergency plans, so becomes multiple use equipment.

In summary, I am very pleased and feel the wait cause by Covid, was well worth it. I, and other family members, will be buying more.

I backed this via kickstarter and have been very happy with my carbon fibre model. It is small enough to fit in a waterbottle pocket, and light enough to take most places, even when you don't know if you will need it. While not as comfy as a chair, it is still much better than standing, sitting on the floor, or a rock etc, and far lighter than any chair.

I have had my Sitpack for some time now so feel qualified to write a review about it.
I originally bought my Sitpack as we were going to a concert and I was bothered about standing up for a long time - I'm disabled and can't stand for a great length of time. I thought that it would help me, which it did.
Firstly, I was surprised at how small it was - about the size of a can of Coke. (I soon realised that I should have ordered the neoprene case with it so that arrived shortly afterwards). It is made of plastic which, I felt, probably wouldn't withstand my weight. After having a good few practice sits on it (making sure that each joint was locked by turning there stem tightly) I used it at the concert - Ed Sheeran in Galway, Ireland, just in case you were interested - and it worked a treat. I used it to sit on for about 25-30 minutes whenever I felt the need, putting it away in-between, which really isn't a problem and takes seconds.
I've been using my Sitpack regularly ever since. It's certainly a step up from a shooting stick which I used before as it is much more convenient and sits nicely under my jacket using the neoprene seat cover and strap.
Overall verdict - it's brilliant! I would never have thought that such a small piece of plastic could turn out to be such a clever piece of engineering. It goes everywhere with me in the back of my car, carried on my shoulder, and is then used when there are no seats available when I'm on my travels.
I'm quite tempted by the new seat - if it's better than my trusty Sitpack then it'll be outstanding - but I can't recommend my Sitpack enough!

Pros: Lighter than any other chair I’ve found. Useful if you find sitting on the ground painful.
Cons: Takes some practice to assemble quickly and correctly. If you don’t lock the legs properly then the chair will collapse!
Hint: simply add some lubrication (WD40 or equivalent) into the telescopic legs, which makes it much easier to set up and pack up. When locking the legs, twist firmly then apply compression to check they’re locked. With these tweaks, the sitpack is much more useable.

I've only used it on the beach so far, takes a bit of getting used to but overall I'm happy with it
