SafcoSafco Zenergy Ball Chair, Active Seating, Anti-Burst, Inflatable Chair for Home Office and Classroom, Black Vinyl

I've had the swivel ball chair for over 3 years and it finally needed to be pumped up a little. It was very difficult to remove the base and I contacted Safco customer service by email. They responded immediately, connected with me on FaceTime and walked me through the process. That's amazing customer service for a product so far out of warranty. Thank you! The product is great and has stood up to vigorous use use by many people (including a college linebacker who's demolished other chairs in my house just by throwing himself into them too energetically!). Personally I find that if I sit on it too long it does create some numbness around the sit bones. On the other hand it passively encourages movement and an upright posture. I much prefer this to a chair for sitting at a desk for under an hour.

I've had it a couple weeks now. Getting the ball inflated just right was a bit of an experiment. The ball is bigger than you'd think it would be and my initial instinct had been to force as much of the ball above the base as possible, but then the ball would sort of shift from use and become a bit topsy turvey. If you push just enough of the ball above the base to firmly fill the mesh and leave the remainder to bulge into the base and inflate until quite firm (they really need better instructions), the ball will not shift. It takes some getting used to as you are using muscles you are likely not used to (I was definitely sore for a couple days). Now; after getting it inflated just right I have to say I love it. It wont roll around the office; is small enough to tuck under my desk if my back gets tired and I want to use a regular desk chair. The swivel makes it a breeze to sit on/get up which can be ridiculous with a yoga ball or with those ball chairs on casters and this is less bulky by far. This thing is great, and it looks nice enough to not be silly in the office.

I purchased this ball stool for my home office as an alternative to a traditional office chair, and it's a big improvement over my regular chair, if only because the bounciness of it reminds me to move more often. I do think it may engage core muscles more than a typical chair does, since the ball's shape and give does force you to stabilize yourself a little, but I wouldn't expect any miracles from sitting on it. I'm relatively athletic, though, and it may do more for someone with weaker core muscles to start with. I find myself getting uncomfortable less often using this chair compared to a typical chair, but I still have to stand up throughout the day to relieve the discomfort of sitting for long periods. It's one of the more comfortable chairs I've used, though, and I'm not sure it's possible to be fully comfortable sitting all day, even if you have a good chair.The chair's very easy to assemble, and the hand pump that comes with the chair isn't all that bad to use - it took me only a few minutes to inflate the ball fully. I didn't have problems with small surface area/sweet spot like some others had, though I'm admittedly on the small side (5' 3"), and it may be different for larger people. The chair seems to be a good height for a standard computer desk with a keyboard tray and allows your arms to be in an ergonomic position while typing and mousing. The lack of wheels seems like a smart choice, in case you lose your balance while sitting. The gliders on the feet move well over hardwood without being too slippery and haven't scratched my floor. It's true the mesh cover isn't as taut and seamless on my chair as it is in the product photo, but it still looks sleek and modern.

Everything I was looking for! I considered the Swopper ($700ish) and another double-sided mushroom looking chair for $300 (I forget name). I also considered the more common ball on a stand chair.This chair looks great. I often work in the dining room off the kitchen. The chair is very discrete (I chose black). Fabric if perfect for my needs...simple and modern and appears well stitched.I like that you have more room for your legs than the very large round ball that would be required to achieve the same height. I easily have this at 23"...can deflate if I want a bit lower but height is perfect for me (I am 5'4" sitting at a standard height table). I thought the pump would be tedious to use and I would be pumping all night...but it took less than 10 minutes. Chair was easy to assemble - less than 30 minutes including brief family interruptions.I also love multipurpose furniture...this can go in my living room or children's play area or bedrooms. Very versatile!!!

I'm getting on in years, and when I play the cello or piano for more than an hour or so, my back starts to bother me. I did not think that an inflated balloon chair could possibly be suitable for me, as my only previous experience with something similar involved those exercise balls that tend to roll everywhere. However, the lack of wheels makes this chair completely different. I was able to use this for performing 6+ hours per day, and it certainly helped reduce fatigue. I imagine that it might help people at desk work also. It seems to encourage a straighter posture, and unexpectedly, I don't end up bouncing very much (probably depends on the level of inflation; you'd need to experiment). Should it be necessary, the vinyl cover would be easily cleaned with a damp sponge, and it's not bad in appearance, being a pretty good imitation of black leather. The sturdy aluminum legs attach easily with 3 screws. The base is black painted particle board (not visible), with what seem to be well-made sleeves for the screws, so that I don't see problems developing there. Took me about 15 minutes to assemble and inflate with the included hand pump.

I really want this ball chair to work. It's just the right size and looks nice at my desk. But the ball is stiff, tight, and uncomfortable. After sitting on it 4-5 hours a day for just one week, all I can say is: "This Hurts!" Hopefully, the surface will soften over time.

Great chair to sit in and doesn’t take up much room around the house. I have two of these and are great for adults and kids love them too. It is alittle bit of a pain to put together but other than that it’s great.

I came across this product all the way back in 2016 when working for a major retailer. My new job has me sitting at my desk for majority of the day and since I work from home, being active while sitting at a desk becomes a challenge.I decided to purchase one for my home office and it has helped so much with my back. Some may say you can buy an ordinary exercise ball and achieve the same results. However you must keep in mind exercise balls tend to roll. With the Zenergy chair it stays stationary due to its 4 feet.For those looking to stay healthy with a work from home job, take a look into this!

My back has never felt better

Very cool looking. This seats keeps you doing a little bit of exercise for your midsection, which is great for long hours seating. I wish it was a little bit taller, or had the option to increase the height. Overall I like it.

If you want a chair that's cute but also a ball, this is the chair for you. I like that I can tuck it under my desk when I'm not using it. I got the red one and it's adorable. I use it for a few hours in the middle of my work day alternating with my old office chair and it helped my lower back a lot.

J'utilisais un ballon d'exercices comme chaise de bureau, mais je l'ai remplacé avec ceci. C'est un peu dur pour les fesses, dû au matériel qui recouvre le ballon qui est assez rigide (le ballon est aussi plus rigide que ce que j'avais). Ça m'a pris du temps avant d'être capable de faire une journée complète, et je dois encore me lever une fois de temps en temps parce que ça fait mal trop longtemps assis. Donc il ne faut pas s'attendre à un confort douillet, et surtout pas au début. J'ai conservé ma vieille chaise de bureau car parfois je dois parfois alterner dû à l'inconfort... Ceci dit, j'avais des douleurs à une hanche, ça m'a beaucoup aidé. C'est un bon achat, très belle qualité, ça vaut le prix. Je mets 4 étoiles parce que ça prend du temps à s'y habituer.
